I put the washer back together and it worked perfectly. It filled and drained like a champ. I next tried the full diagnostic and this time the drain pump did not work - every other diagnostic test is fine. repeated many times - no joy on the drain pump. I suspect that there may be water leaking past the impeller shaft and shorting the motor out. I definitely don't want to clean and dry out the drain pump every time I need to wash a load! Does anyone know if there is a history of these front-loader pumps leaking internally? In any case, I will check the circuit before disassembly this time.
