Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Poor cleaning because wash water is not being circulated effectively.
• Dishwasher fills, but the wash motor does not run or is unusually quiet.
• Weak or absent spray-arm action during the wash portion of the cycle.
• Unusual pump/motor noise or visible water leakage near the pump assembly may occur when the assembly is damaged.

Check Before Replacing

• After the dishwasher fills, pause the cycle and safely check whether the spray arms are wet and have changed position; do not reach into a running dishwasher.
• Listen during the wash portion of the cycle for the circulation motor starting and running.
• Confirm the dishwasher is filling with water before attributing a no-spray condition to the pump and motor assembly.
• Inspect the accessible spray arms and filter area for obvious debris or blockage before replacing the assembly.
• Check for visible leakage beneath the dishwasher or around the pump area, without removing energized components.
• If the model provides a manufacturer diagnostic cycle, use the model-specific instructions to check for a wash-motor or circulation-pump fault.
