With an error code of nd I found the drain pump was not working, by wiring the motor to a patch cord and making sure it would operate and pump. checked wiring from board to motor and all was good. REALLY HAD A HARD TIME finding the power board assy # . ordered it and installed unit rean but had and nl error. this is because there must be water hooked to both hot & cold inlets even when washing on cold . made that correction and unit worked as should.
