Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain poorly cleaned because wash water is not circulated effectively.
• Little or no water is heard striking the dishwasher tub or spray arms during washing.
• Unusual noise from the circulation motor or pump area.
• The dishwasher may fill but fail to wash properly.
• Water leakage may occur near the pump/motor assembly if its seal or housing is compromised.

Check Before Replacing

• Disconnect electrical power before inspecting or accessing the pump/motor assembly.
• Confirm that the dishwasher fills with water and that the filters and spray arms are not blocked by food debris.
• After power is disconnected and the assembly is safely accessible, check whether the pump impeller or chopper area rotates with moderate resistance; do not force it.
• Inspect the pump/motor electrical connector and visible wiring for looseness, damage, or corrosion.
• If the dishwasher fills but produces no spray, distinguish the circulation pump from the separate drain pump before replacing parts.
• After installation or service, restore power and check the assembly area for leaks during a short test cycle.
