Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Unusual howling or grinding noise during the wash portion of the cycle
• Little or no water movement from the spray arms after the dishwasher fills
• Dishes remain dirty because the circulation pump is not developing adequate spray pressure
• Water leakage from the pump assembly or its seal area

Check Before Replacing

• Confirm that the dishwasher fills with water and drains normally before evaluating the circulation pump.
• After filling, briefly open the door and check for evidence of active water spraying or spray-arm movement; avoid placing hands inside while operating.
• With electrical power disconnected, inspect the accessible pump wiring and connectors for looseness, burn marks, or visible damage.
• With power disconnected, check the sump, filters, spray arms, and pump inlet area for removable debris or obstructions before condemning the pump assembly.
• Distinguish circulation-pump noise during washing from drain-pump operation during draining; the two pumps perform different functions.
