Bosch dishwasher issue

The tub on this washer fills up after the wash cycle is done. What could cause this? I had the same issue six months ago and swapped the intake valve for another used one that I had held up till now. Should I try a new valve this time?

Looks like no answers here, any way I scrapped it and bought a Miele with a 5 year warrantee.
I’m done with Bosch!:smiley:

You’re right.

It’s a faulty fill valve .

It’s really easy to install a new one.
