My dishwasher goes through all the cycles. It turns on, fills, but then it's quiet, (no washing sounds). It drains, fills, and it's quiet again. It drains and goes through drying and turns off. The dishwasher is not spraying or washing dishes. Does this mean the washer motor needs to be replaced?
ANSWER Hello Sarah,
You should first remove the screens in the bottom of the unit and check for any debris that can be obstructing the normal operation of the circulation pump. (Be aware that a piece of clear glass is invisible in there and a shop vac works wonders for removing glass chips without having to fish in there with your fingers!). If nothing is found, I would ohm out the motor. If it ohms out properly, you should check for voltage to the pump motor when the unit should be circulating the water. This would point to the control board if the motor is ohmed out good but is not receiving voltage. If it is getting voltage when it should, the pump and motor assembly will probably have to be replaced.
