Amica ZIM627 - Error E1, the dishwasher is filling all the time

After starting the dishwasher, it takes water, the washing process starts and after a few seconds the E1 error pops up and then the water is pumped out (at the same time it is also drawn in all the time). I cleaned the water supply (basket at the aquastop valve) and the entire water coat. Where to find a solution to the problem - what to check?
Please help
Edit:
Could the problem be that the water filling does not stop when the washing process starts? - damaged solenoid valve? How to check?
Edit:
I connected the meter to the solenoid valve and it looks like this:
No voltage> I run a washing program> the water is pumped out (it's probably standard)> the meter shows 240V and the water starts to fill> the washing process starts - the meter shows 0V and the water continues to run.
Is the solenoid valve to be replaced? If there is no voltage, it should be closed or does it work differently?

Replace valve.

Replacing the valve solved the problem. I close the topic.
