Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes are not washing properly.
• Unusual operating noises during the wash portion of a cycle.
• Water leakage associated with the circulation-pump area.

Check Before Replacing

• Confirm the exact dishwasher model uses W10902326 before ordering or servicing; it is listed as the pump-and-motor assembly in the model-specific pump, washarm, and motor diagram.
• During a wash cycle, observe whether the dishwasher fills but dishes remain poorly washed; this can indicate a circulation problem but does not by itself prove the pump-and-motor assembly has failed.
• With electrical power disconnected, inspect the accessible filter/screen and lower spray arm for debris or blockage before attributing poor washing to the pump-and-motor assembly.
• With electrical power disconnected, inspect accessible pump-area wiring and connections for obvious damage or loose connections; do not perform energized electrical testing unless qualified.
