La Nuova Era Cuadra HX Espresso Machine

We are sorry that some parts have been discontinued. In addition, we apologize as the research work is beyond the scope of our free service on Q&A. Our recommendation is that a professional is hired to evaluate and determine the best solution. Again, we are sorry that this is not as simple in terms of time that needs to be invested.

Sorry, considering the age of the machine and being out of warranty, there may be multiple issues which is beyond the scope of our free support services in Q&A. There is no way to trick the autofill relay/board. Although we appreciate your efforts, it is best to contact a local service professional who is willing to evaluate the machine.

You can, but it may get damaged.

Sorry, this part is no longer available.

Sorry, this detailed information is beyond the scope of our free service. In addition, we do not want to be responsible for any damages that can occur.

Probably coincidental, but it sounds like a brain unit issue, especially if the machine does not starting heating again after opening the steam and hot water valve.

We strongly suggest the machine is taken to a professional repair company for evalaution, and the espresso machine should not be used until it is evaluated and repaired.

Please look at the Cuadra diagram in the support section of our web site and search for the part number for availability.

Sorry there are no instructions for re-installation by the manufacturer, nor 1st-line.

You will need to check the bleeder and safety valves for leakage. Then check all fittings.

Yes, you can change the OPV at your own risk of damaging it.

If the blind reaches 12 bar, then this is a grinder or preparation issue.

We are very sorry for the delays. These parts are on their way to us. Unfortunately, many people do not realize the difficulty of our suppliers getting parts from their suppliers in Europe. COVID-19 is more of a mess than people think.

Please check the one on your machine as different batches came with different fuses.

Sorry, you may have multiple issues causing multiple issues. Considering this version is over 9 years old, the machine should be evaluated by a professional repair shop as it could be the brain unit, the refill probe, the vacuum breaker valve, the safety valve, and/or the pressurstat.

Please read. Sounds like the pressurstat or relay for pressurestat (check your threading size before order as some may be 1/8) is sticking. There are multiple versions of this part so a reconfiguration may be needed.

Sure, please follow the process in our parts self-help section.

Here is a link to the H1 hose.  Please double-check the size of your hose before ordering.

If the panel plug part was incorrectly rated, we do not believe it would have lasted 7 years. In fact, it would have melted within the first few weeks and hundreds of customers would have been complaining. After 7 years of use, the replacement was needed from wear and tear. In other causes, this receptacle can damage from an electrical surge or water landing inside on the part as it is below the reservoir. Hence, fill the reservoir on the outside of any espresso machine.

Did you see the voltage rating on the panel plug? Did it say either 110, 220, 230, 240, or even 250 volts?

The fuse box and fuse probably need replacement. However, we are uncertain if any other parts are needed that caused this part to get damaged.

Sorry, the manufacturer has not provided wiring diagrams. There have been several different versions of this machine, so the plate maybe present without the safety. It could also be possible someone removed the safety thermostat and bypassed it.

Either the 41 watt or 52 watt ULKA pump on our website will work.

It is the same valve for both. The only thing that changes is the wands.

It usually does not matter when there are only 2 wires to attach to the pump on this machine.

This ULKA pump can be used as a replacement.

It could be a bad pump, a clogged water softener, a clogged grouphead, and/or blocked tubing inside.

Yes, change the portafilter gasket and dispersion screen as noted. The jet breaker or dispersion disk behind the screen should be cleaned with a blacfklush detergent and/or lightly with a wire brush.

The recommended water softener is on the bottom of the page, click on it, then click on the link for the instructions on how to recharge.

Our recommendation is to power down the machine if not being used within 2 hours. You can leave the pressure alone or deplete.

The V725 on our web site is for this machine.

Yes, our Wega bottomless portafilter will fit.

Yes, our Wega bottomless portafilter will fit.

Hi,

We have a universal one that fits E61 groupheads, SKU 50890.

Please check the steam hole tip. It is probably clogged. If the boiler pressure gauge reads zero, then it may be the vacuum breaker valve on top of the boiler is sticking from limescale.

Yes, there are high temperature PTFE tubes that feed cold water to the boiler. The insides of espresso machines do get hot, so all tubes can get warm to hot. Most water tank espresso machines do have silicone hoses that allow water to travel from the reservoir to the internal pump.

Unfortunately, an electrical issue of this nature is beyond the scope of our free services via Q&A. In addition, considering the age of the machine and the electrical issue, it is best to have a professional evaluate it. On the top menu on our web site, please click on the support link, then repairs either searching our database for a close by repair center or sending it in to 1st-line.

Yes, but since it will only be one unit in red, we would not have the multi-unit discount which would increase the selling price by $250.00 This would be a special order requiring prepayment by wire transfer or certified bank check.

Pre-infusion is the pre-soaking of the ground coffee with hot water under low pressure. The low pressure is from the direct water line or the steam pressure built in the heat exchanger, or the pump pressure by the vibration pump that takes up to 8 seconds to get up to full pressure, or the grouphead chamber.

Hi,

This model is only usable with a water tank / reservoir.

Sorry, you will need to ask an additional question as we go by part numbers and not by descriptions. Please note that the manufacturer, at this time, has made things more difficult with parts as they made ALL NEW part numbers and they have not provided any relational table showing the old part number to the new part number.

We do say 'may' work because La Nuova Era machines had 2 different valves over the years. There was also previous importer who brought them in who may have sold to other customers. If we say 'will' work, then customers will assume we are responsible for machines purchased elsewhere or have a variation of the valve. In essence, we need to be careful as we do not have the machine in front of us, and this is why many companies will not sell parts due to variations by espresso machine manuacturers. Thank you in advance for understanding.

Correct. The insulated wand has a smaller diameter and less power. Sorry, we do not have the original wands any more. We do have an alternative that MAY work.

Please note our free support is for simple issues.

We are sorry many manufacturers, including dealers, do not offer repair instructions for every type of issue - especially issues that become very detailed or complex.

This is why service companies exist, and their technicians are trained through apprenticeships (hands on learning of usually 2 or more years).

Based on the age of your machine and uneasiness of taking the machine further apart, a professional should be hired or the machine should be shipped in for evaluation and service.

The hoses would need to be removed, then soaked in bleach overnight, then rinsed for 10 minutes. The boses can be removed after the 2 side panels are removed.

Only descale if a pump is failing or there is a clog on a non-new machine. Do this after removing the water softener.

Otherwise, recharge the water softener 1-4x per month.

Please short backflush once every 50 extractions with detergent

and one every 10extractions without detergent. Any of the bacflush detergents on our web site will work as most have been carefully selected by our staff.

Sorry, prices are based on euro exchange rates, themanufacturer's cost, shipping and duties. All these costs have been increasing over the past year.

Sorry, we are unsure where there is 15-19 bars of pressure. The gauge needle usually does not exceed 2 bar.

This could be a shorted heating element, or a bad relay, or a bad brain unit.

The grouphead dispersion screen and portafilter gasket should be replaced every 6-12 months.

Please search for and purchase the following part numbers:

F15 - 8mm Grouphead gasket

F277 - Dispersion screen

The water softener is held on to the intake hose by friction. Holding the hose, the softener can be pulled off.

The instructions require a salt water bath and water rinse.

We prefer prevention with a water softener as descaling should only be performed when an issue arises. The reason is that descaling starts premature wear and tear on the metal components as well as any gasket/o-ring seals inside the machine.

Please look inside behind the switch. You should see holding tabs (usually 2 on two sides) that need to be depressed while trying to pry out the panel plug with a flat-head screwdriver.

The losing pressure issue is related to a failing brain unit (there are three versions now on Cuadra as of this writing), a bad heating element, or a bad relay. Lastly, it could be faulty wiring or a switch. For the future, please ask additional questions as a new question to keep the threads related to each other.
