Samsung Dishwasher sump check valve / vane-check drain DD66-00045A

Genuine Samsung dishwasher sump check valve that helps prevent drain water from flowing back into the pump sump or dishwasher tub.

Is This the Right Part?

Common Symptoms

• Water flowing back into the dishwasher sump or tub after draining
• Water remaining or pooling in the dishwasher after a cycle
• Poor draining when the check valve is damaged or improperly seated

Check Before Replacing

• Inspect the valve for warping, twisting, tearing, or foreign-object blockage.
• Check that the valve is seated correctly and that its beveled side faces inward.
• If water returns after draining, also inspect the drain hose, pump, and sink connection because the valve alone may not be the cause.
