JURA ENA Micro 9 " Close lid" error

Hello everyone

I am in despair...a Jura Ena Micro 9 does the following. Switch on and it shows close lid.
I have now checked the microswitch of the bean lid and also the reed contact of the powder chute and found them to be
good or OK.
Powder supply works. This means that the magnetic switch is recognized by the chute.

I have already looked here in the forum, but haven't actually found anything except the switches. Could this be due to the circuit board, and if so, which one?
Does anyone else have any ideas?

take a look here

i have replaced the magnet with a stronger one

I have now tried a few things and realized that it was the rotary circuit board.
