Caffeo Solo & Milk beans still flashing

Hello everyone, I have the following problem: the bean icon flashes and I'm so slowly with the Latin at the end, because I've already tried everything.
Originally I had the problem that the coffee landed in the water bowl and not in the cup, then I thought I overhaul times the machine.
( brewing unit revised, all seals replaced, drainage valve replaced, down holder including seal replaced ).
After switching on the bean icon flashes and does not go away. Microswitch seems to be fine, when I press it the drive moves. ( here, strangely, it sometimes continues to the right towards the drain valve and breaks its teeth ). Normal should turn the wheel to the left and take the valve ?

Please advice
thank you
