Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Poor washing or dishes left dirty after a cycle.
• Spray arms do not appear to move during the wash portion of the cycle.
• Unusual humming, grinding, or other noise during wash-water circulation.
• Water leaking from the motor/pump area.

Check Before Replacing

• Confirm the dishwasher fills, then listen for wash-water circulation after filling; absence of normal circulation is an observation, not proof that this assembly has failed.
• After safely pausing or canceling a cycle, check whether the spray arms have changed position; failure to move can indicate a circulation issue but may have other causes.
• Check the accessible filter and sump area for debris or obstructions according to the appliance use-and-care instructions.
• Inspect the area beneath the dishwasher for visible water traces or active leakage from the pump/motor area without touching energized components.
• Verify the dishwasher model number against the part-fit lookup before ordering or installing the assembly.
