ND code was flashing. Replaced pump. Did not fix. How can I check mother board or is it something else?
Answer Hello Andy. You can test for power from the control board to the pump. If it is not there in a drain cycle, then the pump is bad on the unit. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
How can I operate the drain pump manually. I replaced it and the washer will get to rinse cycle and stop working, everything is on, just no movement
You will want to test the drain pump to make sure that you have 120 vac coming to it. If there is not 120 vac then you will need to check the wiring between the pump and control board. Make any repairs to wires necessary if there is damage. If no damage to the wires then the issue would be the main control board.
I have removed the pump, and opened it. Where the propeller fits it had water. Is that suppose to have water in it?
Answer Vince, Yes there will be some water left in the drain pump DC31-00054A, also in the recirculation pump if you have that option on your washer. The drain pump is the lowest portion of the drain system and there is water left in the drain to form an air tight "sanitary" trap, to reduce the possible "stack gas" and odors from forming and back flowing into the tub.
