Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain poorly cleaned
• Spray arms do not spin or have weak spray
• Unusual noise during the wash portion of the cycle
• Water leaking from the motor or diverter area
• Dishwasher fills but does not begin effective washing

Check Before Replacing

• Confirm that the dishwasher fills with water and that the problem occurs during the wash phase rather than drain or fill.
• After safely stopping the cycle, check whether the spray arms are obstructed and whether the filters or sump area contain debris before condemning the pump assembly.
• Listen during the wash phase for circulation-motor operation, abnormal grinding, or no circulation sound; these observations are not conclusive by themselves.
• Inspect the accessible underside of the dishwasher for evidence of leakage around the circulation-pump, sump, or diverter area.
• If the appliance provides a manufacturer service-diagnostic cycle, use the model-specific tech sheet to test circulation and distinguish circulation-pump symptoms from fill, drain, or control problems.
• Disconnect electrical power before removing panels or handling wiring, and avoid applying external power directly to the assembly.
