Lelit Bianca V3 Dual Boiler Espresso Machine

Sorry, but we do not sell a stainless steel mushroom. 

Testing with a blind to see if it gets over 9 bar.

Yes.  According to Lelit, this conversion kit may be used for either V1 or V2 Bianca.  

Unless they made a recent change on the valves (inside), these are compatible.

There seems to be an electrical issue caused in one of the following components: heating element, safety thermostats, wiring, brain unit, or relay. These parts will need to be checked with a multimeter. It is probably not the PID sensor since a defect in the PID sensor would trigger an alarm error on the LLC.

The hose should be food grade. Check with local plumber's supply distributors or home improvement retailer. Bring the hose with you. Sorry, we do not know your technical or handyman skills o make a determination on ease of replacement on the machine.

We normally would remove the hose, soak it in bleach overnight. soak it in a tube water overnight, then another night in white vinegar to remove the bleach smell, then another night in a tub of water. Otherwise, a suitable replacement should be purchased.

Sorry, the Lelit Bianca has no 3 way solenoid valves inside the machine. Therefore, we are uncertain which part(s) is/are leaking. We suggest you watch our videos:

Bianca Leaking

Bianca Overpressure

And, please read our article.

Unfortunately, we do not stock the rubber feet for the drip tray grid.  It is possible that Lelit USA could have them in stock.  

New gaskets are always more difficult to install as old ones compress. If you purchased the OEM gaskets from us, these are OEM from Lelit directly.

It can be a design change without notification from the manufacturer.

If you are having difficulty, you want to bring the machine and gaskets to a professional as all our suggestions are in our videos and web pages.

The top should be opened and see which hose is feeding the water to the spout on the lower front wall. If either bleeder or safety valve on steam boiler, it may be a boiler refill valve that is leaking while pulling a shot.

Lelit sells that stainless steel drip tray as part of a drip tray/grate kit, part number 4000052.  You can find it by following this link. 

It probably needs a lubrication with PetrolGel in the housing of the cams which is inside the lever.

We have a link for the kit. For home, the small or medium cartridge will work. Please note these solutions are not 100% effective, but reduce the minerals and elements that can damage an espresso machine like happened in your case.

Although we are not water experts, we help in any way to reduce mineral build up. We appreciate you sending our water test results out of your faucet. We can discuss and set up a system upon your arrival. We do not post answers here about water because everyone has different water.

We understand that you may not have limescale on anything else, but does the anything else have 2 large boilers with water? Hence, no comparison can be made.

With the reservoir, the softeners should be re-charged every week and now we are recommending replacing every 4 months instead of 6 months.

For direct plumbing, the best water treatment solution for espresso machines we have found to date is BWT, but keep in mind, these solutions only reduce limescale.

In either case, for those with issues or extremely hard water, an annual descaling or more frequently may be needed. However, more descaling means more erosion of the internal parts when performed too frequently.

This is very, very difficult question to answer. The reason is that everyone's water is different, and in many cases, the same water source can change over time. In addition, we admit we are not water experts. Otherwise, we would be in the water business. All we can suggest is getting a TDS ppm of 80-100 to minimize, not completely stop, limescale causing minerals. Then, maybe descale once per year.

When the pump goes very quiet, this is usually a blockage in the system. That blockage can be anywhere... from inside the grouphead (Bianca in service right now for a moving blockage in the mushroom), to the piping, to the solenoid valves, to even the pump itself. Unfortunately, this is beyond the scope of our free services.

Either your GFIC (in the outlet) is too sensitive or the circuit breaker (in the circuit panel) is old and cuts too fast.

Otherwise, our guess is there is a short in the steam boiler heating element or wire. This would need to be checked with a multi-meter.

It can be a bad LCC display or a computer ribbon cable. Otherwise, it can lead back to the brain unit as well.Sorry, technical support for this issue using a multi-meter is beyond the scope of our free services. Either,

a) you can change the LCC display again, and/or ribbon cable, and/or brain unit, and/or

b) send the machine in for repair or have it checked by a qualified professional or by Breville, the current owners of Lelit.

Thank you for your inquiry. Answers follow:

I’m planning to purchase a Lelit Bianca V3 and possibly a Eureka Oro XL grinder from you. Before completing my order, could you please confirm:

1. That the Bianca V3 will be shipped factory-sealed, in its original unopened packaging from Lelit Italy.
A. Sorry, we open every box twice. Once upon arrival into our warehouse to make sure we do not received damaged goods from shipping. We open the box a second time to test with water only after an order is placed, but before shipping.

2. That it will be a brand-new, never-owned, never-returned unit (not open-box or demo).
A. All demo and returned machines are calculated out of our inventory as such. We would not ruin our 30 year reputation by switching.

3. Whether you perform any additional bench testing before shipping, and if so, that this testing is only done on new units.
A. We test every espresso machine (water only), every grinder (no coffee only operation), new, used or demo, before a customer takes possession in our showroom or before be ship. This does not apply just to Lelit, but every piece of equipment we sell..

4. I predominantly drink espresso and make lattes and cappuccinos for other family members. If you have a better suggestion for the grinder, I'd appreciate your advice. Since you are Lelit’s authorized U.S. distributor, I’d like to ensure my machine comes directly from your new factory inventory and carries the full Lelit warranty.
A. You can certainly call us or email directly for the best options or alternatives. There are 3 tiers for Breville when it comes to warranty and support at the time of this writing and changes may not be updated on this post:

Tier 1 - Retailers who drop ship and handle nothing after purchase
Tier 2 - Reseller who stocks inventory, bench tests, and handles questions and handles service after warranty expiration
Tier 3 (1st-line) - Distributor who stocks equipment, handles warranty, after sales support, and stocks parts (look for parts on web sites).

For Tier 2 and 3 - these companies usually provide services on the machines sold through them.

This has been addressed in a previous question and answer with a YouTube video to address it. This issue is usually indicative of the presence of limescale from hard water or corrosion from purified water.

Sorry to read this. Please make sure the magnetic float is free to move as well as the cap to hold it is in place. The tab on the bottom of the reservoir should also be intact as well as the micro-switch that it presses when the reservoir is inserted.

First, has the water softener been re-charged weekly? If not,  please recharge per the instructions on our web site.

Second, if the problem still persists, there may be build up on the inside of the valve. Please remove the water softener and attach the hose in the tank to the particle filter. next, place in a descaling solution into the reservoir of the Lelit Bianca. Initially, run 16 ounces of solution through the grouphead using low flow. Allow to sit for 8 hours. Repeat. Then do a rinse of 32 ounces of water only in the reservoir. Test the machine with coffee.

Lastly, if the issue does not resolve, the machine may have to be brought in for evaluation and/or service. Please use the contact us envelope at the top of our web page to start this process.

Thank you for your inquiry. Please note that this issue has been inquired a few times in our Q&A section. There are three hoses that feed off of three different parts to the front spout on the lower front panel. They are the OPV, the bleeder valve, and the safety valve. The latter two are on top of the steam boiler. The OPV rarely leaks while in stand still mode. The later two leak in stand still mode. We have made a video how to determine which parts are needed, and the links for those parts are listed in the bottom of the video page.

The video spells it out precisely. Either the hose is not being squeezed fully or the boiler is overfilled with water. It can also be the OPV which has its own hose. One, two  or three parts may need to be replaced. These are referenced in previous answers to questions.

Cool down machine, unplug it from the electrical outlet, remove top cover, disconnect brew boiler PID sensor from brain unit (dual red wire), remove PID sensor from boiler, take a photo of inner portion to send to us, clean with a stainless or steel wire brush or wheel the entire inner portion, reassemble and test. If it does not overheat, you need to treat the water better.

Sorry to hear that. We do not currently stock the OEM Diffuser Aerator for the Bianca.  However, we have an aftermarket version which should be compatible with your espresso machine.  You can find it here - https://www.1st-line.com/buy/c-432-difuser/ 

https://www.1st-line.com/buy/lelit-mc930-2/

If the spout on the grouphead is leaking, we suggest back-flushing as coffee particles may be keeping the valve open. Otherwise, the diagram would need to be researched for the correct part replacement.

If the little spout on the lower front wall is leaking, then this question has been answered already in Q&A as well a video on our YouTube channel.

The OEM version is usually needed. The cheaper priced aftermarket portafilter gaskets may be an issue, such as you experiencing. If the grouphead is worn, a thicker 8.5mm portafilter gasket may be needed.

Sorry to read the troubles. Yes, you can drop off the machine for a professional evaluation. Please make an appointment for a drop off.

This issue has been addressed in a previous question. Please always search for an answer prior to asking the same question as this is what Q&A is for. The question was asked on December 12, 2021 3:55 pm under

"My hot water wand has very low pressure - for steam and at portafilter are fine. I use the machine most mornings and it is most often powered on about six hours. Water used is distilled with Third Wave Espresso packets and I use the Lelit filters, changed every 2-3 months. Ideas?"

There are three hoses that need to be tested. One is the OPV when the pump is running, and the other is the safety valve and bleeder valve on the steam boiler when powered on. You will NOT see limescale from the test. You will see either water from the OPV while the pump is running, AND/OR steam build up in the two other hoses fater the steam boiler has fully heated up.There are specific instructions we have for parts via our self-service parts portal. Parts can change, and this is why it is important to go through our portal.

There can be one or more problems with the machine: bad brain unit, bad boiler refill probe or its wiring, water too pure, and/or scale build up, etc. Since we can not find a record of your purchase from 1st-line under your email, therefore, you may need to contact your reseller. If you purchased from us and require support, please use the contact us envelope on our web site with 1st-line Equipment purchase details.

This is either a bad wire for the refill probe, a corroded or damaged refill probe in the steam boiler, a faulty brain unit, a faulty or clogged solenoid valve not opening. With machine cold and unplugged from the electrical outlet

Check the wire attached to the refill probe.

Remove the refill probe and check for the overlay sleeve (if one exists) being damaged and remove the overlay by 1 inch. Use plumbers tape to on threads of refill probe when re-installing to test.

Solenoid valve would need to be replaced as it is difficult to test. Then replace brain unit if all else fails.

Sorry, your assumption is incorrect, as not every first generation Bianca failed on the Y pipe. There have been cases, especially where the steam boiler overheats or the bleeder or safety valve leaks after warm up. Unfortunately, we have discontinued part 4000027. Please contact Lelit USA for any parts we do not stock as they are now the importers under the Breville umbrella. If a machine is in warranty, we will order the parts.

Sorry, we do not have the specifications. It also depends on the inside because 3 different configurations were used over the last 7 years for the Bianca. Hence, you will need to take your machine apart to get the specifications.

The coupling, at that time of the video, was included with the purchase of the Lelit Bianca espresso machine. Sorry, we do not stock the coupling. Since we do not see your Bianca order with 1st-line based on your email, so it may be best to contact your reseller or dealer for the part as they earned your business. If you ordered from 1st-line, please email us your purchase receipt and we will see what we can do to acquire the part.

Please recharge or replace water softener. Otherwise, please remove softener and re-attach hose to particle filter and test. If noise persists, please hold drip tray, top cover, body (one at a time) to see if noise is corrected. Lastly, without water softener, descale the machine through the grouphead using Dezcal or similar (not Cafiza) and then test.

Sorry, there are no adjustments that can be made on the gauge itself. Our guess is they were damaged in freezing weather. It can also be the tubes clogged and a descaling may help. Otherwise a new gauge is needed. Please use our self service parts portal.

Please note the following: we are not water experts,TDS is a summary number which does not giver underlying chemicals and minerals in the water, water composition can change from the same source, and there is no perfect water for espresso machines.

Sorry for the delay in responding as the way the info was typed it was difficult to determine numbers provided. We sorted the information out into different lines.

We would suggest going with Crystal Geyser, but monitor it as we have seen cases of limescale and in your case, it can become more pure (under 70 ppm TDS) and the steam boiler will overfill. The second would be the RO water, but if the membrane is changed, it can be too pure. But not every RO system is the same and hence it may not be an issue. We suggest measuring your water monthly..

Sorry, the seals are not sold separately by Lelit. The parts that are leaking need to be replaced. Sorry, without evaluating the machine, we can not determine which parts are leaking. The self-service parts portal explains the process to acquire parts.

Lelit previously recommended 80-120 ppm. Please note this is a summary and does not indicate the details which can still lead to issues. Your current TDS is way too low.

It is ideal to check the steam pressure gauge and make sure the pressure gauge for steam moves up and down to show the heating element working. If hot water comes form the same boiler, the hot water valve can be opened to see if there is steam to push out the hot water from the bottom of the boiler.

The next step is to unplug the electrical plug from the electrical outlet and allow the machine to cool down until the steam pressure manometer is zero and no hot water exits the hot water wand.

The process of finding the clog starts with the tip and making sure the hole(s) of the steam tip is (are) not clogged. The second step is to remove the wand from the valve and blow air from either side to the other. The third step is to remove the stem of the valve and check the rings and gaskets. Sometimes the end gasket gets pulled out from the stem and is stuck inside the valve. The final step is to remove the pipe that connects the back of the steam valve to the top of the boiler. Make sure it is clear by blowing air through it.

We are sorry to read this. We will handle this via back and forth email as the solution many be more than one component.

Thank you. Please use the contact form to request a repair authorization to send in for evaluation.

At this point, please run a descaler procedure.

You can if you like, but is usually not necessary unless there is an issue to resolve.

This issue has been addressed already in Q&A. Please search for the question and answer.

The blind filter tests shows the pump working properly.  As long as the pump pressure gauge on the front panel gets to 9-10 bar and the brew pressure gauge on the grouphead moves, this is more pointing to a grinder issue.

Lastly, we suggest operating the machine without the water softener to see if the water softener is the issue.

We suggest testing without the water softener in place.

Depending upon the noise, it can be a bad pump or a bad OPV. We suggest doing a descaling AFTER removing the water softener. We suggest leaving the descaling solution in overnight, and in the morning, with the descaling solution still in the reservoir, do several back flush procedures (without backflush detergent) to get the descaling solution in the OPV valve. Please note Urnex Cafiza is NOT a descaling powder.

The blind test tells us that the pump is working fine, but there are two pressure gauges: pump on front panel and one on grouphead. The front panel should read 10-11 bar. The grouphead pressure gauge is the result of the resistance in your espresso puck

This leads to a grinder issue - grind too fine.

Yes, lubricant and a dispersion screen should be ordered. As for other rings, we usually say to leave good things alone.

If it happens at about 30 minutes, there is a fault somewhere int he steam boiler - maybe a leak hitting wires or the steam boiler heating element has been run dry, which means too much water exited the hot water valve or a boiler refill issue. It is probably best a professional evaluates the unit.

Probably needs a new gasket and/or a descaling. We suggest buying extras as turning the knob too tight can damage these gaskets.

Please review parts diagrams in our self service parts portal. At this time, we do not stock the mushroom. Please contact Breville USA for any parts we do not stock as they are the official distributors for Lelit now.

At this time, we can install the joystick valves free of charge with the purchase of the Bianca and the kit in the same order. Just make a request in the comments section of the order. Please note that the monster wands can not be installed as the machine will not fit in the shipping box and would need to be client-installed upon arrival.

At this time, we are sorry that we do not offer any alternative wood or finishes.In addition, we do not swap any parts as all our parts are managed with inventory levels and the online store can not make those changes.

Whenever there is a machine leaking steam or hot water, use of the machine should immediately cease as the machine becomes an electrical hazard which can result in physical damage or personal injury.

Typically, if the leak is at the top on a fitting, plumber's tape should solve the leak. Please note the machine should be cold and unplugged from the electrical outlet and any plumbed in water line.

As for the leak, we would need pictures and purchase info emailed to us for further assistance. The conversation can be started via our contact us page.

Please check that the tank is inserted correctly with the tab on the bottom of the tank in the correct position.

Second, the float inside the tank to make sure it is not stuck.

Third, disconnect the black audio wire on the bottom from the reservoir assembly and bottom of machine, wait 10 seconds, then reconnect.

If these solutions do not correct the issue, the machine would need to come in for repair as it may be more complex.

The pump probably needs a descaling. Otherwise, the screw and spring may need to be removed for a descaling and cleaning. If this does not correct it, then a new pump may be needed.

We actually advise that any plumbable machine with a water reservoir be used for a minimum of 3 weeks in tank mode. The water can be too pure and the machine can flood your kitchen, office, or business. We do have general guidelines for installation of espresso machines. These apply for all machines that are plumbable.

Sometimes? Unfortunately, we may need to evaluate the machine after it is brought in or sent in for repair. Please note that we only repair Lelit Biancas purchased from 1st-line.

Maybe. Too little minerals can create an overfill of the steam boiler which can flood the area.

This can be a result of a broken stem, a broken c-clip and possibly the brass threading glued to and dislodged from the wood knob. Since part numbers can change and we do not update answers, we suggest using the diagrams on our web site.

The Lelit MC930-2 is the OEM portafilter gasket. We 'believe' Lelit has switch back and forth between a 8.0mm and 8.5mm portafilter gasket based on availability from their supplier. You can try silicone if you like, but we personally seen lower longevity (faster wear and tear).

We pulled out a gasket and measured 8.2mm thickness with a soft squeeze on digital caliper. Very hard squeeze to get to 8.0mm thickness. This is probably why there is no straight answer.

Please watch our video on YouTube. Parts links are on the same YouTube page.

We are sorry to read this. We would suggest you hold or press each body panel or item on the outside of the machine as it could be a rattling body part. Otherwise, the body panels would need to come off and the machine tested to find where the noise is coming from. It may be a bad solenoid valve. Best to email us a link to a video and please include your purchase receipt information from 1st-line.

We are sorry to read this. First, if using the Lelit softener or a direct plumbed water treatment system, the pump may be gasping for water if either is clogged before the pump. Hence the low pressure at the pump gauge. You can also test the machine without the water treatment to confirm.

If not, we suggest running a descaler (Dezcal or Puly, not Cafiza) through the pump and grouphead without opening the hot water or steam valves. Do not allow the descaling solution to go through any water treatment. Le the descaler sit overnight and rinse the next day. See if this improves the noise or rattling or pump pressure.

Lastly, the pump may need to be replaced.

This is only a guess. It sounds like the boiler refill probe is corroded and the steam boiler can not sense the water level. We suggest cleaning it. It could also be a bad bleeder and/or safety valve.

This is only a guess. It sounds like the boiler refill probe is corroded and the steam boiler can not sense the water level. We suggest cleaning it. It could also be a bad bleeder and/or safety valve. Unfortunately, this may need to be evaluated by a professional.

Sorry, we do not know at this time. The only other feed tube is the OPV and this usually does not leak.

Sorry, this one may be complicated. Low grouphead pressure can be a bad pump, a clogged water softener, or MOST LIKELY loss of water in the heat exchange pipes which require filling during the first shot. The loss can come from a leaking OPV, leaking HX pipes, and/or partially opened solenoid valve.

We suggest descaling the grouphead only. Remove water softener before descaling. Otherwise, it may need to be evaluated by a professional as further detailed support is beyond the scope of our free services via Q&A.

Hello.  The recommended grouphead shower/dispersion screen for the Bianca is MC1600069L1 -  https://www.1st-line.com/buy/lelit-1600069l1/.  The portafilter gasket and food safe lubricant are attached to that page as well.  

Sorry, we do not and we do not recommend it because if the external water runs out of water, the machine can have significant damage to the pump and motor as well as the heating elements.

You refer to the hot water spout, but then mention that the steam wand was disassembled. The hot water valve needs to be inspected. Usually, there is debris not allowing the valve to close.

Too much cleaning or overuse of detergent is removing the oils from the lever section of the grouphead.

Always stop using an espresso machine that is leaking until it is resolved. On a cold machine that s unplugged from the electrical outlet, the top cover would need to be removed to see if there are any leaks. If none are found, a professional needs to get involved to assist. If you purchased through 1st-line, please email us your receipt. Otherwise, please contact the dealer that the machine was purchased from.

We suggest testing without the water softener and see if it improves. If it does, it means the water softener needs to be replaced.

If not, then run a descaler through the grouphead and see if it improves.

This problem has been identified and previously answered in Q&A. Please open up Q&A and search with Cntrl +F to find leak. We also have a video on our YouTube channel as well. "Bianca leak" can be searched their to find the culprit.

Since the machine is fairly new, it seems to be a loose connection. Please unplug machine from the electrical outlet and allow to fully cool down. Remove top cover and body panel per one of our videos. Follow the double red wire from the steam boiler (vertical and wider) to the brain unit. Unplug from the brain unit and replug into the brain unit. Try to test the machine before putting body panel and top cover back on. Do not stick fingers inside as to avoid personal injury.

The OPV, steam pressure safety valve and vacuum bleeder valve are three different parts. The OPV is for excessive brew pressure. The Bianca vacuum bleeder valve is for release of vacuum pressure and seals up when there is enough steam built up from the warm up of a cold machine. The Bianca safety valve is for excessive steam pressure when the element, pid sensor, a relay, and/or brain unit allow an overheat scenario.

The vacuum valve and safety valve can leak due to water corrosion. One will either see black, white or green discoloration on the inside portions. They can be descaled after removal from a cold machine and taken apart outside of the machine. However, if the reinstall does not solve the issue, this means water corrosion has usually damaged the inside of these parts beyond a descaling and new ones need to be purchased.

Sorry, the V2 can not be upgraded to V3 at this time as parts are not yet available. This includes a new LCC and internal parts. A white body is also very costly.

We are sorry to hear this. Sorry, it can be the power switch, the LCC, the brain unit or a wire. Too many parts to determine which part is defective.

Sorry to read this. pump noises can be attributable to various external causes. Make sure the reservoir water softener is not clogged by testing with the water softener attached. If plumbed in, reconnect in water tank mode to make sure it is not the plumbing line that does not have the 35psi of water pressure. Too high or too low water pressure can cause a sound.

Next, change the actual pump pressure on the pump. In case and decrease slightly to see if there is an improvement in the sound.

Finally, run a descaler per our instructions on our web site. And, check the inbound side of the pump itself for any debris as we have found one pump with clarified butter on the inbound side of the pump. Please do not ask how it got there as we have no clue.

It can be a broken gicleur or the threads in the holding nut of the flow control is damaged.

Please review our error codes page.

Thank you for your service. Sorry, we would not have any of the parts for a conversion. Just think that we would need the parts for every other country's differences. This is a question that needs to be answered by Lelit, but even more important, the importer in Japan. Again, we are sorry we could not assist.

Sorry to hear this. Here is a list of error codes for the Bianca.

Cause: corrosion from water. This question was asked and answered at least twice below. please search for the question and how to resolve.

Please search for part numbers and/or descriptions on our web site. Sorry, we try our best to refrain from answering here because parts do get discontinued and then the links become invalid and hard to find to correct. As far as we know, the safety valve has not changed.

Grouphead pressure is not really related to boiler pressure. It is related, BUT NOT directly proportionally to the pump pressure.

The pressure gauge on the lower front panel is pump pressure reading.

The pressure gauge on the grouphead is a BREW pressure gauge. This gauge shows the result of the resistance that equates from the fineness of the grind, the amount of coffee in the basket AND the tamping pressure. This pressure will likely read differently than the pump pressure gauge as

a) it is measuring different parameters,

b) it is in a different location,

c) it is known to be different even when using a blind.

We do have clients who have used the Lelit Bianca in a coffee shop, in a mobile coffee truck, and/or mobile catering. In December of 2019, we performed a fund raiser event at a local charity and the Bianca made well over 250 8 ounce cups of cappuccino in a 4 hour period.

Please be aware that some towns, cities, counties, and/or states require NSF approval, and then there are the same that do not require any approvals as it is up to the local health inspectors.

It is best to find out from your local health inspector on the requirements, including the grinder.

Leave stock and raise it when entertaining or using in a commercial environment.

It sounds like the refill probe is scaled up. It needs to be removed and cleaned with a wire brush. The machine can be dropped off for service if you like.

Just use backflush detergent to clean. Please do not run the risk of taking apart the grouphead if you are usnure what you are doing.

We suggest not descaling unless there is a problem with the machine.

We strongly suggest diluting the tap water without 50-80% of distilled water and continue to use the Lelit water softener (recharging every week and repalcing every 6 months). The BWT may counteract the Lelit softener. Hence, if using the BWT to a separate dispensing faucet, then use the BWT only.

The ball joint may need some high temp food grade grease, such as Petrol-Gel or equivalent.

Please backflush as particles may be holding the valve open. Otherwise, it can be too fine a grind that is creating too much back pressure.

This means you have a short inside the machine somewhere. The short can be a heating element inside either boiler, the solenoid valve, or wiring that burned up and is touching metal. The machine, unplugged from the wall outlet, would need to be visually inspected inside with both top cover and body panel removed. The wires would need to be removed from each heating element, and the element tested for an ohm reading which can range from 8-20 ohms.

A multi-meter is needed to check the ohms or each heating element. All parts and wires need to be inspected for damage or a short. If all the GFI outlets are older than 3-4 years, it could be bad GFIC outlets.

Sorry for the delay. We have learned a few machines did not have "any or very little glue/sealant" to hold the threaded fitting to the inside of the wood knob. If you have a permanent glue to place on the inside of the wood, this would work. The c-clip does need to be removed from the stem before re-insertion.

Please review our white paper on GFIC.

It needs resistance in the portafilter to show resistance pressure, or the gauge area tube area is corroded with oxidation of limescale.

We recommend the higher price one as it is the more modern design like the Bianca.

Sorry to hear about this. The top cover would need to be removed. Power on the machine and allow to heat up. WARNING! Do not stick your fingers inside as it will get very hot. You will see two hoses exiting the steam boiler - one on the horizontal safety valve and one on the vertical vacuum breaker bleeder valve. Check to see which hose has a steam vapor going through. Be careful as you can squeeze each one for 2 seconds to see if there is a visible or verbal puff. If yes, this is usually corrosion from hard or too pure water. After the machine is completely cooled down and unplugged from the electrical outlet, both hoses can be removed by tugging on them. They may break. The affected part can be removed and soaked in descaler solution overnight. Then rinsed and reinserted using 2-3 rounds plumbers tape on the threads. Test. If problem continues, the part would need to be replaced as well as the water choise needs to be re-evaluated. We are not water treatment experts, so we are unsure about the system you have.

Please check without coffee. Your water softener may also be clogged.

Urnex Cafiza can be used for backflushing, BUT NOT used for descaling as some customers confuse.

Water softening recharge instructions can be reviewed.

We do not suggest descaling unless there is a water issue causing machines issues.

As for the low water notification, please make sure the black audio cable under the machine is taken out on both ends and re-inserted.

Sorry, at this time, we can not confirm a fitment of the "normcore" nor any other suggestions of alternatives.

Wemo.

This seems to be the safety valve.

We have found, in cases of limescale or oxidation, either the bleeder (vacuum breaker) valve or the safety valve or both would not create a good seal. One way to test this is to remove the top cover and pinch one hose at a time (both on steam boiler) to determine which part is leaking. When pinched, the bubbling should stop. WARNING!!! BE VERY CAREFUL as one can get burned and we assume no responsibilities for any injuries or damages from performing this diagnostic task. You may also see the bubbling without pinching.

This is a result of backflushing with too much detergent or purified water - both result in the lubrication being removed. We suggest high temp food grade grease inserted in the cams at the inside end of the stem of the grouphead lever. Otherwise, over time, coffee oils may re-grease this area.

We do not recommend descaling. It is better to be preventative with controlling your water to be soft. Watch our videos on YouTube.

Hi,

Here is a link to the part: 2200102.

Hi,

Sorry, the nut/screw is only available with the Lelit Grouphead Flow Control Assembly.

Empty water reservoir. Open steam and hot water valves to allow evaporation of both boilers. Lift lever on grouphead to allow evaporation of grouphead.

Upon return, recharge the water softener AND fill reservoir and run water through grouphead (24 ounces) and allow steam boiler to refill. After refilling stops, remove 4 cups of water from the hot water wand/valve every 5 minutes until a reservoir full of water is depleted.

We are sorry as these are kitted together.

We are very sorry that we are not water nor water treatment experts to be able to answer your question.

Please spend time to scroll down this Q&A area and find the answer which is already posted.

We strongly suggest recharging the water softener weekly. As for the brand of water, we are unable to comment as we have seen it go both ways - good and bad.

If purchased from us, please use the contact form on our web site to start the support process.

These are usually sold only in our kit. Please use the contact us form on our web site as we barely ever replaced these.

Sorry for the delay as we had to ask Lelit about this as we admit we are not water experts.

First, the softener needs to be rinsed after a recharge in a salt water bath - usually 5 minutes or more for sinsing.

Second, Lelit stated, "yes, it is normal, you have to completely flush the boiler. It is happen because of the concentration of TDS in the boiler due to the steam production: let assume in the boiler you have 1 L of water with 100 ppm. If you consume 0.1 L of steam and you fill the boiler with new freshwater you have in 1 L 110 ppm TDS."

Third, Lelit stated, Following the client’s description we understand that he measured the water coming from the boiler, meaning while the machine is ON. The Conductometer/TDS meter measures the conductivity of water, some models convert the data expressed in μs/cm to ppm by a conversion factor, that generally is between 0.5 and 0.65. For example: 100 μs/cm = 50 ppm CaCO3. The measure displayed by TDS meter is temperature dependent: Water electrical conductivity increases with temperature but with a non-linear behaviour. Consequently, the fractional change per degree Celsius m f is not constant. Generally the TDS meter are accurate at 20-25°C. (image provided by Lelit)

We recommend using it in tank mode for at least 3 weeks.

As for plumbing, it is not easy and everyone has different scenarios. We have a guideline to be used for plumbing in.

Yes, you may need to even leave the steam valve open longer as this will be the only way to get solution into the steam boiler without opening up the machine. Try to funnel the steam to a vessel that can take the heat. The boielr can eventually run out of steam and rebuild. You will hear the pump refill the water that was converted by steam.

As for #12, please skip.

We have seen this on a few Bianca espresso machines. It is limescale that clogs the pipe from the water valve to the bottom of the boiler. Please run a descaler through the steam boiler by opening the steam valve (since the water valve is not working) for at least one hour so the solution can reach the boiler. Check back in 24 hours and see if the hot water valve works. If not, then more solution is needed. Remember to remove the water softener beofre inserting the solution. Here is a guide.

Brita is ok, but after the 1st week of usage, their softening mechanism does not work as well. By the 3rd week, it is shot. It is good for filtering other contaminants. At the end of the day, do NOT use any formulated waters.

Sorry, these will not be available until next year.

Sorry, we are unable to break up kits.

We understand and appreciate your feedback. Please understand our reasoning and we work is based on cause and effect. We are only guessing the water. It may be your cloth or the pressure applied.

However, this is the first report of the logo being washed or taken off. Not one other customer in 3 years has reported this.  As with any painted item, it is subject to wear and scratches. In fact, the very first prototype still has its logo intact.

Other machines have painted steel frames and scratches tend to rust. Many espresso machine manufacturers usually do not cover cosmetics.

Please email us a picture with a serial number of the machine and a picture. We will see what Lelit decides.

Also, to have this repaired means the entire machine needs to be disassembled to remove the entire front panel which is on the front frame. This means both valves on front come out, the grouphead, LCC, and power button and gauge have to be removed. Please search for the panel on our site MC1400159 and you will see the panel. We also have a sticker that is slightly larger than the painted logos MX129.

We are very sorry to hear about this as this is the first we heard or seen of this issue. Lelit replied, "...the LELIT logo on Bianca is not a sticker, it’s applied as paint." Your water may be corrosive to the point that it removed the paint.

Best to use the original packaging. Make sure both boilers are drained. Leave the steam and hot water valves open as well as the grouphead lever in the up position. This will allow any water that may freeze to push out and not damage the pipes.

The pump pressure has no relationship to the steam boiler.

When you hear the pump, make a note of the steam pressure gauge reading. Test while sitting still powered on for a few hours.

Please read the entire Q&A. Portafilter gaskets and screens should be replaced every 6-12 months. The filter should be recharged every week and replaced every 6 months. Descaling should only occur if there is an issue.

There is a possibility that your steam boiler is overfilling on your new machine as the water refill probe has changed on the newer machines. On both machines, fully warm up and then open the hot water valve and measure how much water comes out when the pump kicks on. Shut valve immediately. And count the seconds on each machine it takes for the pump to stop and then for the temp to get back up by pressing the right button on the LCC to see actual steam temp.

The bleeder valve may be leaking, and you will see steam continuously come out of the front lower spout. Plug the unit into a GFI outlet, and check if it trips the outlet as this would indicate a heating element not submerged in water.

Lastly, the steam boiler may be overfilled with water. The Bianca espresso machine would need to be cooled down and unplugged from the electrical outlet. The top cover would need to be removed. The wire on the refill probe needs to be disconnected. The refill probe needs to be removed by the outer nut. Do not pull on the probe nor loosen the smaller nut. Wire brush the bottom tip of the probe. There is most likely build up there.

If you are using formulated water, please stop as this water causes issues with the probes and PID sensors.

Sorry, we do not provide measurements.

Thanks for the email. The Bianca espresso machines arrive and we sell out of every batch very quickly. We do not even have any used machines to replace it, and we would never ruin our reputation. The grill on top is not perfect as one may think as these are all hand made in Italy - they actually come with a little bend of the one rail. Yes, please email us a picture.

Sorry, you have NOT provided enough information.  There are 2 gauges!

If the brew pressure gauge on the grouphead, then this is a grind fineness problem.

If it is the pump pressure gauge, the pump may need to be adjusted, descaled, OR the water softener is clogged.

MC931 only includes the valve. We are unsure why you think this part is defective as we have never replaced one on a Bianca. These valves last a LONG TIME UNLESS there is limescale.

Lelit just confirmed with us 2 hours ago that there is no Version 3 of the Bianca at this time. We are unsure where you are getting this misinformation. If they are selling something as a Version 3, then it is best you contact them.

On the last batch of May 2020, the tamper was 58.55mm. The baskets are fits for this tamper. This is subject to change in the future.

Sorry, we do not know of any.

We are very sorry that we do not know of any.

Please review what Lelit has emailed:

In case of Error 3 on Lelit Bianca, we usually recommend this procedure:

1. RESET the machine (press in + button and power on, wait 20 seconds and power off)
2. Remove the eventual resin filter and fill the water tank with plain, bottle water
3. Insert the water wand into a tank containing at least 1 liter of water
4. Open the water tap on the machine
5. Turn ON the machine and follow the “first start” procedure
6. After having refilled the coffee side, the machine will fill the water tank
7. Wait until there is at least ½ l water in the water tank
8. Turn OFF and afterwards turn ON the machine
9. Close the water tap

If not solved, there is a possibility that the refill solenoid valve wire or refill probe wire were disconnected in shipping at the top of the boiler or at the brain unit. On older machines, the solenoid valve may be blocked or the refill probe needs to be cleaned.

First, NYC water is most likely good drinking water, but from our experiences, not the best water for espresso machines. Most formulated waters, in our experience, have been worse in terms of creating over heat situations. We suggest using water without magnesium and/or calcium. Please read: https://www.1st-line.com/customer-education/water-choice/ and watch our video: https://www.youtube.com/watch?v=peX93sksu6k

First, the grouphead gasket should be changed every 6-12 months. More use or more time powered on, then more often.

Second, the brew pressure gauge in the grouphead shows the resistance created by your grind, the amount of coffee in the basket, and your tamping pressure.  As long as water stops or slightly dribbles when the paddle is in the left position, this means the flow control is working. If the blind is put in the portafilter and the paddle is all the way to the right, the brew pressure gauge should reach 10 or more bar and shows the gauge is working properly.

Thanks for the email. Since you know if it is not the water, we would be interested in your findings on the cause of overheating as every single case of an overheat has been attributable to the water. In fact, you can watch our video on this.

Unfortunately, the PID sensor on the steam boiler will need to be removed and wire brushed. There is most likely a slight film from the water that is not allowing the sensor to read the proper temperature and thus causing the overheat, which is the higher pressure as indicated here. So far, the several customers who had this issue resolved it by cleaning the sensor, changing their water, or becoming more frequent in their water softener recharging (once per week) as well as replacing their water softener every 6 months.

It is similar to our VBM video.

Right now, we are expecting May 15 or shortly after.

Our recommendation is power down an espresso machine if not being used for more than 2 hours.

Usually, if there is a problem within the grouphead, the pressure usually will not reach 4 bar. Please put in the blind filter and test with paddle in full open position (right side). If it reaches within 1 bar of the pump pressure gauge on the front panel, then this is pointing to the grinder.

We emailed you directly as this will be covered under warranty.

Thanks for the inquiry. Our first recommendation is to use the machine in tank mode for a minimum of 3 weeks to make sure your water is ok with the machine - meaning not too pure which would cause an overfill issue.

Second reason is that you can check the position of the machine before plumbing in. Then we can assist with the BWT as this system works quite well with the Bianca.

Please review our video about overheating. The PID sensor on the steam boiler probably needs to be wire brushed.

This can happen from backflushing with too much detergent or water that is so pure that it removes the gel inside the lever arm on the grouphead. Coffee oils can sometimes revolve this. However, we do sell PetrolGel to insert  into the chamber when the lever arm is removed.

Sorry to hear about this. Please try to insert/remove the drip tray on an angle. These will sometimes come off, but we have not seen much on our prototype machine in our showroom. These can be purchased on our web site. Please use the diagrams to search for part numbers. Sorry, sometimes part numbers change and we do not post part numbers.

The water you are using is known to cause issues. Please use softened water. We would need a video emailed to us to determine the noise you are experiencing.

We sell a bunch of different backflush detergents on our web site. All of them work well. Sorry, we will have the water cartridges in the next month or so. Sorry, demand has been very high.

In many cases, manufacturers will not share their specifications so as to prevent manufacturers from easily copying. Their response to the size is M8,50x0.75-6g. Please note that every manufacturer reserves the right to change specifications without notice to us or to customers. Therefore, we are not responsible for any future changes based on this information.

2200100 - REV00

The brew pressure gauge should go up to 9-11 bar with the blind filter basket inserted into the portafilter inserted into the grouphead. AND the paddle turned all the way to the right. It can take up to 10 seconds to reach this bar pressure on the grouphead gauge. If it does not, please contact us.

If you do get this pressure with the blind but NOT with your coffee, then the grind is NOT fine enough or you have too little coffee in the basket or both.

Too much backflushing with too much detergent. Should resolve itself with coffee oils. Otherwise, use PetrolGel to re-grease.

Drain the pump, boilers as best as possible, leave the grouphead lever up as well as both valves open. Try not to store in freezing weather.

We suggest recharging the Lelit water softener minimum once per week. Replace it every 6 months. In addition, look at the Oscar90 on our web site as an additional layer of water treatment to help prevent limescale build up - limescale build up causes the PID thermo-couples to not accurately asses the programmed temperature and cause an overheat situation.

It really depends. If the coffee boiler is warmed up and the steam boiler is still heating, there is an overshoot programmed on the coffee boiler to reach "about" 217 d F which would put the water at over boiling. You may also have the coffee boiler temperature too high, or your elevation is coming into play.

If this happens after the steam boiler completely heated to programmed temperature, then you may have a small leak in the manual grouphead valve (spout on bottom of grouphead, not the front panel) or the OPV (overpressure valve which drains into the front panel along with the vacuum breaker valve on the ). This is something that will need to be watched - the top cover needs to be removed to watch the OPV.

Sorry, we do not see any from Lelit. The only thing we can suggest is buying the dual spout version and purchasing a generic single spout.

Outlet, then WEMO, then surge suppressor, the machine plug.

Sorry, we are currently out of stock. These are on order and will be available in about 2 weeks or more.

We just received our parts shipment.  Here is a link to the part: 2200108

Remove and reset the parts inside the reservoir. There could also be a crack in the water softener or a pinhole in the hose.

There is an algorithm to overheat the coffee boiler so the steam boiler can get full power to heat up faster. Otherwise, like other dual boiler espresso machines, the power alternates between both boilers and the stability decreases.

We have seen overheat situations attributable to limescale build up on the PID sensors in both boilers. It is imperative to properly treat the water as preventative maintenance.

Remove the water softener and water from the reservoir. Fill the reservoir with 32 ounces of white vinegar.  Run the white vinegar through the grouphead and let sit for 2 hours and then rinse the reservoir, fill with water, and flush out the white vinegar. test th emachine to see if the issue improves. If it does, then the steam boiler sensor will need to be manually cleaned with a wire brush. Contact us.

Sorry, we can not recommend this water source. First, there is usually not enough water pressure in most cases. Second, you are making the Bianca pump do double duty of pulling and pushing while the Bianca tank is designed with a gravity feed. Third, if you run out of water while the steam boiler is trying to refill, there is a possibility that the heating element will go through a meltdown without water and the safety thermostat. Lastly, a water treatment system needs to be in place. Again, we strongly advise against this water source.

Unfortunately, we cannot say YAY nor NAY as we do not know what are the short or long term effects are.

One of our reps will contact you for further assistance.

Sorry, we do not have references from Lelit on the 4 home steam tip. Please provide a Lelit part number. We believe your references were for an aftermarket part.

Thanks for the emails. We had one previous case where the threading on the top nut because worn. We send out a replacement nut which should resolve. If not, please email us directly.

Turn paddle to full open. You will need to remove the paddle and needle valve nut (not bottom larger nut). Then check the gigluer inside. Email us pictures.

There should be zero flow when the paddle is to the left. Issues can arise if limescale builds up. We have seen cases of limescale that have stopped a good seal from occurring with the paddle all the way to the left.

In addition, we are starting to realize that limescale may be a culprit in the gigleur from breaking off because customers may be tightening the paddle with more force to create a zero flow, and then the needle gets stuck in the gicleur, which then breaks off.

It is best to put the machine in tank mode, remove the water softener, and run 16 ounces of vinegar ONLY through the grouphead full open on the paddle. Sit for 2 hours. Rinse with 32 ounces of water. Test.

The boiler could be too full. Or, there is limescale in the valve. With the machine cold, the safety valve should be removed and inspected on the inside. However, it should not be taken apart.

Yes, this happens when the in tank water softener is not charged minimum every 2 weeks or when the in tank water softener is not replaced every 6 months.

If plumbed in, it can be too much or too little water pressure, and the same as tank mode when a water softener or filter is inline.

So far, we have not replaced any pumps since September, 2018 when we started selling the Lelit Bianca.

You can test without the softener to see if the problem goes away. If it does not, a quick descaler (without softener in place) can be run through the grouphead.

More than likely,  the internals, of where the lever inserts, needs lubrication. We do sell Petrolgel for this.

This is caused by build up of excessive oils from the espresso extraction, too much detergent used in backflushing, too many backflushing sessions with detergent, and in some cases we have see, water that is too pure in that it strips away the oils.

Sorry to hear this. An adjustable can be used as well as a 22mm crescent wrench can be used to tighten the holding nut.

Recharge water softener minimum every 2 weeks with a salt cold water bath for 20 minutes, then cold water rinse with faucet running for 5 minutes. Hard water more often on recharge.

Please note you are not using distilled water. If you did, the steam boiler would be overfilling and water would constantly push through the front spout on the front panel. We can only suggest using soft water, and not purified, distilled, nor reverse osmosis water.

As for Third Wave water tablets, we have customers in the past 3 months with overfilling issues on their heat exchanger and double boiler machines as well as 2 Bianca owners experiencing issues. Hence, we can not recommend it unless other owners have used it successfully.

Also, back flush with detergent once every 50 extractions using our procedures with the paddle in the full open position.

From a liability perspective, 1st-line has to recommend using the water softener. Without it, we would get blamed for limescale. Unfortunately, we have not tested this scenario. The other issue is different RO systems produce different results in the water. In other words, we have seen some RO systems create too pure water where the steam boiler is overfilling and leaking, and we have seen other systems where limescale builds up inside the machine.

In your case, we suggest using the softener. If the boiler overfills and the front spout is continuously releasing water from an overflowing steam boiler, then you can choose to remove it. If the steam boiler still overfills, then the water may still be too pure.

This will become a trial by error scenario as there are so many different scenarios for water.

We have seen this issue last week with a different Bianca customer. It is imperative to use SOFT water, and not hard, purified, distilled nor reverse osmosis water.

With hard water, limescale will typically slide down the boiler wall and accumulate at the bottom of the boiler. The accumulation will clog the brass output coupling that connects to the pipe that leads to the back of the hot water valve. This coupling on the bottom of the boiler will also build up oxidation from purified waters that can also block this coupling.

There are 3 ways to correct this. Machine should be in tank mode and not connected to any plumbing. Unplug electrical cord from electrical outlet in 1st and 3rd cases where machine is taken apart.

The preferred but more difficult way that our technicians will do is

a) Remove the water tank assembly, top cover and body from the machine. Remove drip tray and and any other loose items.
b) Disconnect the pipe from the back of the hot water valve
c)  Turn machine upside down so the bottom of the steam boiler faces up
d) Disconnect the pipe from the hot water valve from the coupling on the bottom of the steam boiler
e) Remove the coupling for manual descaling and cleaning.
f) Reassemble with plumbers tape only on the coupling going into the steam boiler. The other 2 connections are compression.
g) Test the hot water valve before placing the back cover back on. Check for any leaks.

The easier way, but longer way, without disassembly is...

a) Put the Bianca in tank mode, remove the water softener, and reconnect the hose to the adapter inside the reservoir. Power on to full heat.
b) Fill the reservoir half way with descaling solution or white vinegar
c) Place the steam wand tip into a large cup, cover the cup with a towel, and let the steam continually run
d) It will take hours for the descaling solution to get in to the steam boiler.
e) When the reservoir runs out of solution or vinegar, refill with water.
f) Let the machine stay heated, please another large cup under the water wand tip and open the water valve. If solution/vinegar exist the wand, the problem is solved. If not, repeat the process with the reservoir filled with a half tank of solution or white vinegar.
g) If successful, fill reservoir with cold water, and drain a tankful of water through the hot water valve. The process to avoid damage is remove 4 ounces, let machine refill from reservoir, remove another 4 ounces, let machine refill from reservoir, and repeat until steam depletes. Steam pushes the water out of the hot water valve. Let machine make more steam so more water can be pushed through.

The third way is...

a) Allow machine to be fully cold. Remove tank assembly and top cover.
b) Disconnect the wire to the probe nearest to the outside side wall. Do not touch nor remove the other wire as it will damage the PID sensor.
c) Remove the probe. There are two nuts, and removal is with the larger nut. Do not pull on the probe nor loosen the smaller nut as this will damage the boiler refill probe.
d) Get a funnel and pour about 8-16 ounces of strong descaling solution or white vinegar into steam boiler.
e) Reassemble probe into boiler and re-attach wire.
f) Let sit for 8 hours.
g) Warm up machine and test the hot water valve.
h) If successful, fill reservoir with cold water, and drain a tankful of water through the hot water valve. The process to avoid damage is remove 4 ounces, let machine refill from reservoir, remove another 4 ounces, let machine refill from reservoir, and repeat until steam depletes. Steam pushes the water out of the hot water valve. Let machine make more steam so more water can be pushed through.

Everyone has different opinions based on backflushing.

Excessive backflushing can cause excess stress on any espresso machine pump. Hence, we always recommend short backflushing. In addition, too much detergent can create clogs in the grouphead.

Any quality backflushing detergent is acceptable.

Sorry, we do not sell the Quickmill Flow Control Device. Hence, we are unable to answer this question.

Hi,

The MC747PLUS is more suited for the Bianca. The MC747 is for the smaller Lelit models like the PL41 Anna or Glenda.

Sorry for the severe delays as we had a massive power outage last week from the tropical storm that hit New Jersey and wiped out electrical power for almost 70% of the state.
