This is the circulation pump motor that drives water through the spray arms during the wash and rinse cycles in a dishwasher. It pressurizes water so it can reach and clean dishes effectively. Replace this motor if the dishwasher fills with water but doesn't spray, makes a humming noise without circulating water, or if dishes are coming out dirty despite proper detergent use.

Dishwasher would start begin to fill with water then there would be 4 5 short "hums" or "buzzes" it would then shut off and drain what water had filled John S. • Granite Falls , MN • September 19, 2017
Figured it was either the capacitor and/or motor. Ordered both parts to be sure. tried changing the capacitor first; same problem. Replaced the motor (leaving the new capacitor in place). Unit now works fine. Overall an easy fix once you get the washer out and tip it on its side or top to get access to the motor area.
