Dishwasher completes full cycle but dishes still have food residue — pump has lost pressure and spray arms are not receiving adequate water flow.
Dishwasher fills with water but nothing sprays — the circulation pump motor has failed and is no longer pushing water to the upper or lower spray arms.
Unusual humming, grinding, or rattling noise during the wash cycle, indicating a seized impeller, worn motor bearings, or debris lodged in the pump housing.
Standing water remains at the bottom of the tub throughout the wash cycle because the pump cannot circulate water up through the spray arm circuit.
Water leaks from the pump housing area beneath the dishwasher due to cracked housing, failed shaft seal, or deteriorated hose connections on the circulation pump.
💡 Pro Tip: How to Diagnose a Failing Circulation Pump
Your part is likely the culprit if you notice any of the following:
⚠️ Dishes come out dirty or with food residue after a full wash cycle
⚠️ Dishwasher runs but you can't hear water spraying inside the tub
⚠️ Loud humming, grinding, or rattling noise during the wash cycle
⚠️ Water sits still in the bottom of the tub — not being sprayed up to the arms
🔍 Tech Note: Before replacing the pump, check the filter and sump for debris blockage. If the motor hums but doesn't spin, the impeller may be jammed — clear any obstruction first. If the motor is silent or trips the breaker, the pump winding has likely failed and replacement is required.
