Whirlpool dishwasher wash pump not engaging
I have a Whirlpool ADP4601 dishwasher that, when you start a cycle, momentarily operates the drain pump, fills up with water and then after a few minutes, drains all of the water back out regardless of wash cycle. I have ran the Whirlpool diagnostics test. The test runs fine other than the wash motor does not engage.
The obvious suspect is the wash motor but is there anything else I should check before the headache of removing the wash motor? My next step was to hook a multimeter up to the wash motor to check coil resistance and monitor for voltage when starting a cycle.
