Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Dishes remain dirty after a completed cycle
• Little or no water spraying from the spray arms
• Unusual grinding or whining noise during the wash portion of the cycle
• Water circulation stops even though the dishwasher fills and drains

Check Before Replacing

• Confirm that the dishwasher fills with water and completes the drain portion; this helps distinguish circulation problems from fill or drain problems but does not by itself prove the sump/motor assembly is defective.
• After disconnecting power, inspect the accessible sump and spray-arm openings for visible debris or foreign objects; remove only loose, accessible debris.
• Observe or listen during the wash portion for normal spray activity and abnormal pump noise, without placing hands inside the operating dishwasher.
• Check the appliance technical sheet or parts diagram for the exact model before ordering, because the assembly may include multiple components and model-specific parts.
