I solved the problem.
To be able to remove the main unit from the compressed state I disconnected the cables from the drive unit and connected power from external power supply.
This way I could run it to the state where the main unit could be disconnected.
But the problem wasn't in the main unit, the problem was the drive unit.
I didn't order the Adapterkabel 87790 when I ordered the new drive unit, I just cut off the cable from the old unit and soldered the cables to the new unit.
I soldered the cables red to red and black to green, but what I didn't check was if the polarity was the same, so when I now tested the new unit the polarity was changed, the drive unit was going in the wrong direction compared to the old unit, so that was the reason behind the lockup of the main unit.
After switching place of the cables in the connector and putting all back together again it was working as it should.
Before assembling everything, I took it all apart and cleaned everything, it's a lot of dirt collected during the years, especially the last step where the coffee comes out, that canister is not so easy to clean, and it's not awailable as a spare part here, the part number is MS-0039705.
The coffee tastes great, hopefully it will be running for a couple of years again
