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.
Pro Tip
Poor cleaning can result from blocked spray arms, a clogged filter, insufficient water, or other faults; verify basic water delivery and blockage conditions before replacing the circulation pump and motor assembly.
