Whirlpool Dishwasher Sump Motor (W11416362)

The Whirlpool Dishwasher Sump Motor circulates wash water through the sump and pushes it through the spray arms during the wash cycle. It helps maintain water movement needed for cleaning by driving flow from the bottom of the tub to the spray system. When this motor is not working as designed, water circulation drops and wash performance can change.

Common causes of failure include normal wear of the motor bearings, damage to the impeller, debris that jams the pump area, or electrical issues such as an open winding or a failing start component. Seals can also wear, which may let water into the motor area and lead to noise, binding, or a motor that will not run.

These symptoms can help you decide if this sump motor matches the problem you are seeing:

Spray arms do not spin or have weak water pressure during the wash

Dishes come out with food soil because water is not circulating well

Humming or buzzing from the sump area with little or no water movement

Grinding, rattling, or loud droning noises during wash circulation

Intermittent washing where circulation starts and stops during the cycle

Cycle runs but cleaning is poor, especially on the upper rack
