Thanks. I've got a pressure-fill system. I removed the water inlet system and water level switch housing assembly. Switches seem to be functioning. I did notice that the O rings that go around the level switch assembly and where the water inlet system connects to the water level housing assembly do not make a seal (there are gaps). I reassembled and ran through a regular sysle. It works, but only if I plug the vent hole in the water inlet system whenever the tank is filling to keep water from flowing out of the vent. I noticed a lot of air mixing with the intake water from both the water inlet system-water level housing assembly connection and through the water level switch assembly. Should those be seals or is there something else that might be causing the overflow?

The float switch seems ok, but I've been running the machine with the panel off to watch it and when filling, the water inlet system is overflowing out of the overflow hole (or vent--whatever the hole is designed for) and the heater may not be working. Is there a likely part failure causing the overflow?

Thanks--I may try replacing that too. But more problems--after an apparently successful regular wash cycle, motor will not shut off again and it won't cancel (although display does show "CL"). Test program shows aqua sensor and heating faults, which didn't show up before. Test program will not advance beyond that. Can you suggest a next step?

Replacement of the level switch assembly has fixed the problem--thanks. Now I have to stop water from seeping in I believe through the drain hose even though I restored the loop in the hose higher than the drain.
