Caffeum Perfectus Minima Dual Boiler Espresso Machine

The two hole may work when regulating the steam thorough-put with the steam valve knob. We are inquiring ACS about the 1 hole tip as we could not find any compatible ones within our inventory of steam steams

This E61 flow control as worked for other customers.

Sorry, we have decided to delay the colored versions as demand was very low and there is a minimum order quantity with the manufacturer as we can not just order 1 unit. We do have the stainless steel in stock.

Sorry to hear this. We suggest cleaning the PID sensor of the steam boiler. We have seen this issue occur when the PID sensor is partially corroded from the water. If it continues after cleaning, please use the contact us form on our web site with your serial number, purchase date, full name and problem described along with this solution.

Remove the lower nut and inspect. Lubricate with high temp food grade grease, such as PetrolGel or similar. It may also need tightening of the nut when re-installed.

Most E61 type bottomless filter holders are compatible as long as the portafilter does not state lips larger than ~6.5mm thickness.

The PID sensor on the steam boiler can be corroded with limescale or oxidation - especially so if the temperature bounces on the screen . It can be cleaned. With machine cold, the double red wire on top of the large steam boiler needs to have its two pin black connector disconnected.

Then without twisting or bending the double red wire, the nut where the double red wire goes into, needs to be removed with a crescent wrench. The internal potion needs to be wire brushed. Reverse he process to install and test.

Otherwise, replace the PID sensor. In a worst case scenario, the brain unit needs to be replaced or the hating element is damaged.

Sorry to read this. Please send us photos.

This problem is usually from water that is too pure, re-mineralized water, or water that is too hard with calcium or magnesium.

However, there was one batch of machines that had this issue (video) and need a wire to be moved.

Sorry, 2022 2nd quarter.

Sorry, this machine is tank only.

Sorry, but probably not until the Fall.

Sorry, times lines are all in disarray. However, we did get some in.

The knob covers need to be pushed out. Then there is most likely a nut inside that needs to be removed.

As for the portafilter, manufacturers will not always tell us when they change the bolt size. Is the one we provided too small or too large on our bolt?

Yes. Unfortunately, there are many delays in Europe. However, the machines have left Italy. We just do not have an ETA because the ports in Italy are backed up.

Yes.

Sorry, these engraved drip trays are currently not available. The pricing will increase on the new batch coming in as this is part of the cost increase.

Pretty much all of them, except maybe the screws, are needed.

Sorry, they must have changed this without notification. This is why we put this statement on our web site. In addition, they do not sell their steam tip separate from the wand.

If you want, we can take one off of our demo, but you would need to send the 2 hole to us so we can put it on our demo machine. One of our complaints was that the steam tip could never be fully placed over the drip tray when bleeding. So, if you decide to switch, you will have this issue.

There is a probability there may be an offset in the inner programming, which is off.

Thanks. There are so many videos to make, so some day, one will be done.

At this time, both boilers are stainless. From what we see, there is no pre-heat of the water for the coffee boiler from the steam boiler.

Timing of extraction is of an opinion, as it depends upon your taste and the beans used.

V725 is the best option.

This happens when the water is too pure. We have more information on this topic.

Sorry to hear about this.  Please note that these wands are a little heavier than the standard wands, so it may move by itself a little. We also add a little food grade grease to the ball joint when we test to make the gasket last longer.

You can try about 1/8th of a turn on the nut.

We will test our flow control device kit i the near future. Sorry, we can not confirm if kits by others will fit.

This would be difficult to determine since the pre-production model may have a different boiler or a different sized connection than the ones we sell. Your purchase of the Ascaso one just proves our point that this inquiry is not as easy as one thinks to answer.

Unfortunately, we are unsure at this time. We did forward your inquiry to ACS. However, since Italy is closed due to the Coronavirus, you may want to contact the person or company you purchased the pre-production machine from as they ultimately should support your inquiry and know the specifications. Once we hear from ACS, we will update our answer here.

This bottomless/naked portafilter fits best on the Minima!

From our experience, it heats up the coffee boiler first with priority, then the steam boiler. This is the only way to make it work at 15 amps at 110-120 volts.

At 110-124 volts, it takes the coffee boiler about 20-25 minutes under room temperature of 60-70 degrees F, and the steam boiler an additional 25-30 minutes.

The steam boiler needs steam pressure to push the water on the bottom of the steam boiler through the hot water valve and wand. Hence, the steam boiler needs to be set at 212 degrees F or higher.

In Italy, the hot water valve was created to rinse the portafilter, and not for Americano beverages as North Amercian customers have adapted. Although it can be done on the minima espresso machine, we suggest only remove 4 ounces of water from the hot water valve, then allow the steam boiler to refill before removing another 4 ounces of hot water. This is because if the water level drops too fast on the steam boiler, the steam boiler heating element can get damaged from lack of water. This applies to all HX and double boiler espresso machines with boilers smaller than 4 liters.

Sorry, on new machines, the programmers sometimes forget to ask the technicians about the electrical.

The coffee boiler is 1000 watts. The steam boiler is 1200 watts. The 110 volt current alternates between the two boilers, but not to both at the same time. This allows 15 amp service with minimum 110 volts up to 124 volts out of the outlet with a 15 amp circuit breaker.

We usually say 'should work" because we are not at every remote location to check the amperage rating of the circuit breaker, the age and type of wiring behind the wall, nor the actually voltage coming through the circuit. For examples, some very old homes have may have a 15 amp circuit breaker, but less than 110 volts at the outlet. If the volts are too low for any particular reasons, no 15 amp espresso machine will work correctly and/or potentially cut the circuit breaker. In other words, we have to try to think of every scenario, because there is always that one machine in one customer's home where it will not work... So, we say 'should work"....

We asked the programmer to correct the web site with greater detail.

15 amps should be sufficient if a dedicated outlet. 20 amps will work better if a grinder is on the same outlet.

Sorry for the delay as we had to confirm with the manufacturer. They responded,

"This machine is equipped with a vibration pump that is more gentle compared with a rotary pump. Basically, the E61 not have a real preinfusion chamber, but have like an expansion valve that operates at around 5 bars to avoid the shock of the 9 bars that the rotary pump push from the beginning.

The vibration pump have a short ramp up of pressure and also the volume of water in the same time is lower so the puck not suffer."

Not really. There is a three stage switch - off, coffee boiler power on only, and coffee and steam boiler both power on.

Hence, the steam boiler can not be powered on by itself.

There are two switches on the front panel on the Minima espresso machine. The top switch is to start and stop the espresso extraction. The lower switch for power has three positions:

Top - Power on coffee boiler only
Center - Power completely off
Bottom - Power to BOTH boilers.

Unless we are missing something here, the steam boiler can NOT be turned on INDEPENDENTLY of the coffee boiler. Please review picture below.
