Customer Question

I found your post on with a similar problem reported and yet my results to resolve the lack of spraying inside my dishwasher are similar. All other operations of the dishwasher are working fine (dispense, fill, drain, heat, etc). My pump motor works when I apply 110V power directly to it at the unplugged connector and does successfully spray water if I leaveit filled. If the motor is properly connected and I do the dishwasher's self test there is no error reported yet step 4 (power is at the motor connector for wash cycle) the motor does not activate so the spray does not perfrom. It coninues succesfully through the rerst of the test. Isolating power and a successful pump does not dictate which part is not working...motor or control board or otherwise. I researched further and found this post elsewhere: but have found no isolated issue as I have 120-130V of power on the violet/purple of the pump motor connector when it should be running and at all times the white wire traces out as continuous back up to the door latch switch. Thoughts?

  1. Does the motor make any humming or buzzing noises when it should be running?
  2. Do you have a meter to perform any electrical testing with to see if power is getting sent to the motor?
