Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain dirty because wash-water circulation is reduced or absent.
• Unusual noise during the wash portion of a cycle.
• Water leaking from the pump, motor, or diverter area.
• Dishwasher may stop or fail to operate when the circulation motor does not run.

Check Before Replacing

• Confirm the dishwasher fills with water before evaluating wash circulation.
• After the wash motor should be operating, carefully listen for circulation-motor operation and check whether the spray arms have changed position; do not place hands inside a running appliance.
• With power disconnected, inspect the filters, sump opening, and spray-arm passages for food debris or other obstructions.
• Check the pump-and-motor area and surrounding sump for visible leakage, damaged seals, loose wiring, or disconnected connectors.
• Do not assume a failed pump from a no-drain symptom alone, because this assembly does not include the drain-pump motor.
