HELP please! Thank you in advance for your answers.
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-
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
