Samsung Dishwasher Circulation Pump Motor DD31-00004A

Is This the Right Part?

Common Symptoms

• Poor cleaning caused by reduced spray-arm water flow
• Continuous humming or droning during the wash cycle
• Grinding noise during washing if the pump impeller is damaged
• Spray arms not receiving adequate wash water

Check Before Replacing

• With power disconnected, verify that the dishwasher filter and sump area are free of visible debris that could restrict circulation.
• During a wash cycle, observe whether the spray arms receive water movement; do not place hands inside a running dishwasher.
• Listen specifically during the wash portion of the cycle for continuous droning or grinding rather than assuming the pump is defective.
• Confirm that the dishwasher fills with water before evaluating circulation-pump operation.
• Before removing or testing the pump, verify the dishwasher model and compare the installed part markings with DD31-00004A.
