Brewing unit moves up, brewing operation does not start

Hello,

HELP please! Thank you in advance for your answers.

Problem:
After the brewing unit has been started up, the brewing process unfortunately does not start. This causes the brewing unit to shut down again immediately. Then follows the error message: "Clean the brewing unit".
Previously
you could
hear
the ceramic valve motor as soon as the brewing unit was started up.

The ceramic valve /

engine works fine per SDS menu (CV1, CV2, CV3 etc).
Grinder works
fine, but dry coffee powder disappears in the collecting tray.

Warm tea water

works great, milk frother function works also. Already done:
- ceramic valve removed and completely
cleaned (as described here in the forum)- brewing unit completely cleaned-
hoses
removed
from ceramic valve
and openings cleaned- decalcified, cleaned
SDS / Service Menu:

- up/down brewing unit works without
problems-

CV1 t/m CV8 via 'start' button seems to work without problems

If the BE drive motor turns too hard, this message appears. You would have to remove the drive, open the motor, re-grease the two bearings of the motor shaft, or the two balls. It's a lot of work.

Hello, C-spine,

I'm glad you answered, thanks for the tip, even
if it's a lot of work, I'll try it anyway. Hopefully the device will then work again. I'll let you
know.
Many greetings,
