After checking the power supply ordered a new pump assembly (part no. AP436087). After installation of pump and relay, motor would not run. I called customer service and a new pump assembly was sent. It still would not work. Checked other componets and found a bad door switch. Replaced door switches and, even though it seemed to be OK, I replaced the timer as well. Packaging was suspicious for both pumps (cardboard had gotten wet, parts poorly molded, relay package torn open). Am I missing a protective interlock or something else? What should I do?

You should read 120 volts AC across yellow and white. If there is no power there, you will want to look for a broken or burnt wire going to the motor. If there is power to the motor, you have a bad pump/motor assembly and will need to get another one. Hope this helps.

There was 120 volts between white and blue leads. I tried jumper wire 99001917, still no. motor. Tried another motor with jumper an it worked. Bottom line, I got one "new" motor that was bad, and needed the jumper wire.
