Jura Impressa E25, water runs into collection container

Hello
, at my law school, the water runs clear into the bowl. I suspect that the solenoid valve switches incorrectly if this is possible. When brewing, the tappet is not switched, the water then goes into one through the drainage valve and comes out at the outlet. The coffee powder remains completely dry. Then the solenoid valve switches briefly and jumps
back again. On

the photos you can see the condition during brewing, on the left the water runs

out.
Greeting Dirk

See if the white cap is still firmly attached to the plunger. It can't be taken off.

Thanks for the tip, I have now mounted an aluminium cap, water still runs through the outlet only and does not go into the riser pipe.
Seals are all new, but were all still intact
.

Did you get the aluminum cap right? If this is not up to the stop on the push rod then the water also runs out there. Pushrod with cap should be about 53mm. Rather even 1 or 2/10 mm less.

Thank you, the cap wasn't completely on it. I had already hewn right up with a hammer, but was obviously not strong enough.
Now the machine works again.
