Gaggia synchrony Compact does not grind

Hello to all technicians among you,

I have a serious problem with my Gaggia synchrony Compact.
Although our machine was getting on in years, it worked perfectly until yesterday.
Since yesterday, after an apparently too intensive cleaning, the coffee grinder no longer grinds the coffee beans.
I have done the following:

The complete brewing group is disassembled into all parts and cleaned.
The coffee bean container is dismantled, the rubber grommet above the grinder is removed and the grinder is vacuumed.
The upper part of the housing is unscrewed, the flat cable to the control buttons is pulled off and the housing is blown out with compressed air.
All screwed together again.

Then coffee beans and water filled in and started. Now it is so that the grinding of the beans is skipped and it starts immediately the coffee output, however without coffee, only with water.
Is now a tea machine

White somebody Advice?

Would be very happy about a positive answer.

>My greetings
Olaf

So, it was the microswitch with jammed mechanics at the dosing tank.
So it's over.
