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.

Installation Notes

• Disconnect electrical power and shut off the dishwasher water supply before service.
• Remove the lower rack and lower spray-arm assembly as required for access.
• If the dishwasher must be pulled from the cabinet, disconnect the water, drain, and electrical connections carefully and protect the floor from residual water.
• Remove the drain pump, thermistor, wiring harness, and retaining sump tabs or clips as applicable to the installation.
• Seat the replacement assembly by aligning its locating tab or slot, then reinstall the retaining tabs or clips so the assembly is properly seated and sealed.
• Reconnect the circulation-motor harness, thermistor, drain pump, drain hose, and any applicable sensor connections before reassembly; restore water and power and check operation for leaks.
