Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain poorly cleaned despite the dishwasher filling with water
• Little or no spray-arm movement or wash-water spray during the circulation portion of a cycle
• Unusual humming, grinding, or other abnormal noise during washing
• The dishwasher fills and drains, but provides little effective washing action

Check Before Replacing

• Confirm that the dishwasher fills with water and reaches the wash portion of the cycle before evaluating circulation.
• After safely pausing or opening the dishwasher according to the appliance instructions, check whether the spray arms are wet and have changed position; lack of spray-arm activity can indicate a circulation problem but is not conclusive.
• Listen for the circulation pump and motor during washing and compare its sound with the appliance’s normal operation; abnormal noise alone does not prove this part has failed.
• Inspect the spray arms and visible filter/sump area for obvious food debris or blockage before condemning the pump and motor assembly.
• If electrical testing or component removal is required, disconnect electrical power and follow the model-specific service documentation.
