I recently changed the pump motor as the dishwasher wasn’t draining all of the way. It works great now but it is now making a buzzing sound during the wash cycle. I took the main motor off and cleaned out the impeller and other area’s that had build up. The dishes are getting cleaned but the noise is annoying and I don’t want to drop a couple hundred bucks for a new motor if it is working and if there is something else I should check.
Any advise is helpful.
Sometimes it is just the wire that holds up the back end of the motor.
Hold the motor and move it slightly when it is running to see if this is the cause.
If it is loosening the wire and moving it slightly may solve thaproblem.
Or perhaps itis too loose.
