The circulation pump motor forces water through the spray arms. When it fails, water fills the tub but is never sprayed — leaving dishes dirty. Replacing the pump restores full water pressure and spray coverage.
A seized or burned-out pump motor will cause the unit to fill normally and then drain without any wash action. This part directly addresses the root cause of that fill-drain loop with no cleaning.
Worn motor bearings or a damaged impeller create a grinding or loud humming during the wash cycle. Replacing the pump & motor assembly eliminates the noise and restores quiet, efficient operation.
A partially failing pump motor may still circulate water but with insufficient pressure, resulting in poor cleaning results. A new pump delivers consistent flow rate and full spray arm rotation.
💡 Pro Tip: How to Confirm Your Circulation Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Dishwasher fills with water, then drains without any spray — dishes come out dry and dirty
⚠️ Loud grinding, humming, or buzzing noise during the wash cycle instead of normal water spray sounds
⚠️ Dishes are not cleaned or rinsed properly despite a full wash cycle completing normally
⚠️ Water circulates weakly or intermittently — spray arms spin slowly or not at all
🔍 Technician Tip: Run the dishwasher's built-in diagnostic cycle (press any 3 buttons in a 1-2-3, 1-2-3, 1-2-3 sequence on most models) to confirm a pump fault code before ordering. You can also access the motor behind the lower kick plate — remove 2–4 screws, locate the pump harness, and check for continuity. A failed winding will read open circuit (OL).
