Dishwasher completes full cycle but dishes remain dirty or gritty due to insufficient water circulation through the spray arms.
Water stops circulating completely — pump motor has seized or impeller has failed, leaving dishes completely unwashed.
Water drips or puddles under the dishwasher caused by a failed motor shaft seal on the circulation pump assembly.
Circulation pump emits abnormal grinding, humming, or rattling sounds during wash cycle indicating bearing or impeller failure.
Pump runs but circulates water with reduced power, resulting in poor cleaning performance especially on heavily soiled loads.




💡 Pro Tip: Is Your Circulation Pump the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes come out dirty or gritty — water is not reaching the spray arms with enough pressure
⚠️ Dishwasher runs through a full cycle but dishes remain visibly unwashed
⚠️ Loud grinding, humming, or rattling noise during the wash cycle
⚠️ Water visible leaking from beneath the dishwasher — caused by a worn motor shaft seal on the pump
🔍 Diagnostic Tip: Pull the dishwasher out and look under the unit for water staining or active dripping from the pump area. A leaking motor shaft seal is the most common failure on Samsung DW80 series pumps and requires full pump assembly replacement — the impeller and shaft are not serviceable separately.
