Whirlpool Dishwasher Pump and Motor Assembly W11025157

Genuine Whirlpool OEM dishwasher pump and motor assembly that circulates water from the sump through the spray arms during the wash cycle.

Is This the Right Part?

Common Symptoms

• Dishes remain dirty after a completed cycle.
• Spray arms do not spin or have weak water pressure.
• Dishwasher makes unusual pump or motor noise during washing.
• Dishwasher fills but does not properly circulate wash water.
• Leakage may occur from the pump or motor area if its seal or housing is damaged.

Check Before Replacing

• After the dishwasher fills, briefly pause or open the door and verify that water is actively spraying from the arms; use caution because internal water may be hot.
• Check that the filters and spray-arm openings are free of food debris or mineral buildup before attributing weak circulation to the pump assembly.
• With power disconnected, inspect the pump-area wiring and connectors for looseness, visible damage, or corrosion.
• With power disconnected, check for accessible foreign objects around the pump or sump area without forcing or disassembling the motor.
• If the dishwasher has a model-specific service diagnostic cycle, use it to check for a wash-motor or circulation fault; do not treat a fault code alone as proof that the assembly has failed.
