Whirlpool Dishwasher Sump Motor Assembly (W11416363)

The Whirlpool Dishwasher Sump Motor Assembly circulates water through the sump and pump housing to the spray arms during wash and rinse cycles. It helps move water at the right pressure so the dishwasher can clean and flush soil from dishes while keeping water flowing through the filter area and drain path as designed. This assembly can fail from normal wear to the motor bearings, damage from debris in the sump, or electrical issues such as a weak winding or a failing connection. Running the dishwasher with a blocked filter, broken glass, or heavy food buildup can strain the motor and reduce water flow. Over time, moisture and heat can also contribute to internal motor failure. If you are troubleshooting cleaning or circulation problems, these symptoms can point to a sump motor assembly issue: Dishes come out dirty or gritty because spray pressure is low Little to no water movement inside the tub during the wash portion of the cycle Unusual humming, grinding, or buzzing noises from the bottom of the dishwasher Cycles seem to run but cleaning performance drops without other changes Intermittent operation where the wash action starts and stops during a cycle Water remains in the tub because circulation and filtration are not working as expected
