Bosch Verobar 100

Hello, coffee rarely comes out of the nozzles of my Bosch Verobar 100. Hot water works.
The
ceramic valve was changed about 3 years ago. When you

request a coffee, you hear how the beans are ground, the

brewing unit is controlled and water is pumped.

Either coffee comes out very slowly, or the machine breaks down again immediately, discharges the coffee into the container, there is a

loud hiss and water vapour comes out of the door. So pressure seems to be building up. So far I have tried the following
:1. outlet removed, it is a bit clogged, but even if the coffee
could come
directly from the
hose, nothing happens.
2. ceramic valve
removed and cleaned.
3.
tried
another brew group
...
Now the question is, can it be the ceramic valve again, even if pressure
is built up?

Can something clog between brewing unit and outlet, how

do you get there? Thank you René

I'd try cleaning the microswitches on the ceramic valve... with contact spray or something.
You may have to open the microswitches with a suitable object.

Okay, thanks.
Since pressure is built up that only escapes from the brewing unit when the coffee powder is emptied, I thought it would be clogged afterwards
.

I'll disassemble the microswitches
