Try to stay away from pricy Bosh washers, and dishwashers.
I can offer this with a Bosh. If you get a E13 error it's the pump.
It's a pretty easy fix. You can get a generic pump for $50.
Most disguarded Bosh washers are due to a pump. The computer is second on the list. It's not worth fixing if it's the board.
I've been meaning to put a fan on my washer's computer board. There us definitely room in there for a computer fan.
