Brew group is not detected

Hi all,

after the revision of my Barista F73 1-101 the brew group is not recognized. I had also disassembled the brew group.
Disassembled the drive again, replaced the top microswitch, checked all cable connections, but still the brew group is not recognized.
When I operate the microswitch at the top by hand nothing happens.

What did I do wrong?
What should I check?

Did you have the cables off at the switches? Think there is a problem with the wiring.

Good morning Schlawi,

that would be great if you could compare the wiring!

If you could post another picture?

This is the drive

I can't photograph the switch on the top right.
The blue cable is on the left side of the long side of the switch, like the other switches on the drive. The yellow cable is right next to it. Hope I have described this understandably

Hello Schlawi,

I have found the error, the switch at the top left was connected incorrectly.

Thank you for your effort.

Unfortunately, still no coffee comes out of the machine. Have already replaced the drain valve including spring. Everything made nice and clean.
