The door on this thing will be the death of me. I had a problem with water not heating last year. The thermostat wire had snapped in the door. Took the machine mostly apart this time to try and understand the continuous pump problem. Rejoined two more snapped wires – one orange one going to the float switch and another white one, which might have gone to the pump. I think that with the orange wire severed it failed safe, thought it was flooding and this is why the pump was just running and running.
Anyway, I strongly recommend replacing all the thin sensor wires if you're already there replacing one. As the previous poster says, it's just a matter of time before they break. Awful design. How many of these ended up junked because of this?
