Greetings,
Our GE Monogram ZBD5900 has begun failing to drain and defauting to an error mode. Sometimes pulling the circuit breaker and pushing various control buttons gets the washer to drain and complete the cycle. The error indication is a blinking "rinse and hold" LED. Usually if I bail all the water out of the washer and then cut the power, the washer will then cycle properly for one cycle. What controls the drain cycle? Just the drain pump? Or does the sump float switch affect the drain cycle? I've removed the control board and the components, traces, and connectors all look fine. Any suggestions would be greatly appreciated. Thanks.

I actually had a drain pump fail. It made noise like it was working, I even removed it and ran it in the sink. SOMETIMES it would pump, sometimes not. It even looked like it was spinning, but I think it was actually oscillating back and forth. I replaced the pump and like was good.There is no actually level sensing. There is a pressure switch on the right had side that is pretty accessible. That senses "empty" or "not empty". Contacts 1 and 2 are closed when the sump is empty, open when not empty. Contacts between 1 and 3 are opposite. No wire goes to 3. You can check this with a ohmmeter. The pressure sensor had a small rubber hose connected to it to provide the connection to the sump.
