KRUPS EA8010 - Calibration when replacing the complete heating unit

Hello.
Coffee maker Krups MODEL EA8010PE / 70E-1213R
I replaced the complete brewing unit with the boiler with piston cylinders ....
(MS5A21198 Complete heater GROUPE SEB) NEW
Do I need to calibrate the first time I use the 1cm thick tablet that is inserted between the sieve and the piston?
If so, how exactly to do it, do you need to enter any special service mode?
Thank you in advance for your help.

Calibration was done in EA90xx, because there the grinder has electronic regulation.

I received a message about the need to calibrate this model EA8010 (EA80XX) from the owner of the express, who was told about this by a Belarussian from the service where six months ago there was an express.

When the coffee got to me liquid coffee from above and below, no ejection of the coffee tablet, the sieve hanging over the edge of the boiler, broken cam that controls the ejector arm, jagged edges of the sieve ...
I decided to replace the whole

Earlier I had already replaced the seals and the complete piston on the EA8000 model, I did not do any calibration and everything was ok, because the customer did not complain.
But since there was information about the need for calibration, I preferred to ask KRUPS service technicians
I have repaired many different machines many times, mainly saeco, bosch, and deLonghi.
I have not met the need to calibrate the brewer before, although here is another solution, a water-driven cylinder, not an engine, so I preferred to ask

EA90xx has a grinder:
, where the thickness and quantity is electrically controlled by electronics. There, after replacing the electronics, grinder, band. boiler, perform initial calibration.
In EA8xxx we have a grinder with manual adjustment and we do not calibrate there (I have never heard). There is nothing about calibration in the official service documentation for this model (EA8010).

Oh buddy Marcin, I can't quite agree.
In EA8010 from some year, I don't remember exactly the calibration was introduced, admittedly quite "archaic" on the microswitch but such a function occurs and to be honest it can also be tuned well.

Can the author of the subject post me a picture of the side electronic board with all the connection cubes plugged in? Then I will be able to promptly.

What is the purpose of calibration in this model? For this model without display.

Regulates the working time of the grinder. I must admit that this extra bajer is very problematic both in use and calibration.
Lack of coffee in the container and starting the grinder automatically calibrates the machine.
Why KRUPS decided to do this, I have no idea and I sincerely hope that they will retire from it anyway.

For calibration, the below module with microswitch is located at the bottom of the boiler unit

Exactly. It rarely happens that we make a few coffees (e.g. friends came) and bad luck. The coffee has run out and the machine needs repair (i.e. calibration). These and similar models are probably from 2005 (formerly XP72xx) and the lack of calibration was good. The fact that after 6-8k of coffees made, the efficiency of the grinder was decreasing, but before that he went to the service for something else and adjusted the service so that the grinding thickness and disc height was optimal.
I guess what some people can't sleep at night, if they do not come up with an additional sensor that makes life difficult for us.


EDIT.

I have added the calibration process for Krups machines: link

Thanks for showing interest.

Buddy "nioop".
adds some photos from disassembly.
Is this the model?


To a colleague MARCIN.SLASK
I was watching the file to which you provided the link. Unfortunately, I think I prefer the text over the pictures, I can't read comics.
Maybe some translation if you can. I think I'm dark.
Yes, I will try to read it tomorrow, maybe I will succeed, today I am very tired

Yes, this is a calibration model.
Colleague Marcin posted the correct and only calibration instruction, which seems to me to be extremely transparent, as long as it can be called when pushing this calibration ..

But I noticed a serious mounting error in the pictures:



This clamp cannot point up, down or any side, but it cannot point up.

During operation, it blocks the ejector of coffee discs and the ironing piston usually breaks it irretrievably.

Holy right. The ejector works flat there. Just gently rotate the hose collar and it will be OK.

Nap and I can read now. I see!
Thank you very much for the link and information.

Still a question because the instructions show that you should use a pill while at the same time pouring coffee beans, I understood correctly?

As for the error of mounting on the photo, it was informative, the caliper was when the machine came to me, it was possible that it was the reason for the guide's rupture, (the photos do not show the crack).
Attention very right! Thank you.

By the way. Would it be a mistake to wear a twisted band here?
Of course properly arranged.
Is it safer to use the crimped one as in the original? What are your experiences?

And one more question about the calibration plate, can some colleagues share information about its dimensions?
KO-CY1014 what is its height and diameter?

Hello. I have a coffee machine as in the subject and I have a problem, i.e. water comes out from underneath the coffee machine and does not go to the spout. I can ask for advice what could be damaged.

Of course.
The stem seal, one of the cylinder seals, the cylinder itself, the piston seals, the distributor, maybe a tube may have been damaged This is how you can guess without dismantling the equipment. Undress and see where it flows from. Replace damaged item.

After replacing the complete heating block and removing the remaining minor defects, although the machine could not be properly calibrated, the process was always unsuccessful, but the machine flashes, the customer is satisfied.
