Krups EA 9000 Error code 6 Fill water circuit

Hello,

I have a problem again what I don't really understand why. I've already browsed the forum here, but none of this seems to work. I'm really despairing of what it should still be.

Machines type is a Krups EA9000. Machine worked before and everything was great. Now it will display "Automatic maintenance" directly when switched on and wants to fill the water circuit. At 3/4 of the screen the piston should go down and up again. I'm afraid nothing's moving. And of course the whole thing goes into the 2nd round and then comes error code 6.

- What I've already done:

- Water filter turned out
- Drainage valve cleaned, greased and hose checked for passage
- Inlet hydraulic unit checked for clogging, hose also at the moment off to check if it pumps water from the WV
- Brewing module unit tried to push down the piston goes also
- Water distributor opened for the 100th time. If there is still enough grease inside, the gaskets are not displaced or clogged by grease and the plastic plates are also in their recesses, the gears are assembled in their initial position so that the gears face each other.
- Switching contact unit at WV checked. Switch also both and no cable break present, as well as the engine runs also.
- Flowmeter also turns nicely, but exchanged as a precaution
- Dirt sieve was also not too renewed anyway
- Water inlet to the WV checked also free, otherwise it would not fill.

I have the impression that the WV does not find the correct position or the correct output, so that water arrives at the hydraulic cylinder.

I would be very grateful for possible solutions, or what else I could try out.

Hello! I have recently the same problem with the ea9010. Was there a solution to the said problem? Is there something defective in the electronics?

Hello,
any news for that particular problem?
