Is This the Right Part?

Common Symptoms

• Poor cleaning performance
• Spray arms not spinning or weak spray
• Water remains cold during the cycle
• Unusual pump noise or continuous droning
• Dishwasher stops during the cycle
• Leakage near the circulation-pump area

Check Before Replacing

• Disconnect electrical power before inspection.
• Confirm the dishwasher fills with water and that the filters and sump area are free of food debris or other obstructions.
• With power disconnected, inspect the accessible pump/impeller area for foreign objects that could restrict circulation; do not force the impeller.
• Visually inspect the pump area, hose connection, sump seal area, and electrical connector for evidence of leakage, damage, or looseness.
• Use the appliance’s model-specific service documentation for any electrical resistance or error-code checks; do not assume a pump fault from a symptom alone.
