Water remains pooled in the bottom of the tub after the wash cycle completes — the most common symptom of a failed drain pump motor.
Loud grinding, squeaking, or humming during the drain phase indicates the impeller or motor bearings have failed inside the pump assembly.
Samsung dishwasher displays a 5C, 5E, or OC error code signaling a drain failure — often caused by a seized or burned-out drain pump motor.
A cracked pump housing or deteriorated rubber gasket seal allows water to leak beneath the appliance during or after the drain cycle.
The dishwasher stalls mid-cycle and does not advance to the dry phase because the drain pump cannot clear the tub water as required by the control board.




💡 Pro Tip: Is Your Drain Pump the Problem?
Your part is likely the culprit if you notice any of the following:
⚠️ Standing water or puddles left in the dishwasher tub after the cycle ends
⚠️ Squeaking, grinding, or loud humming noise during the drain phase
⚠️ Wash cycle fails to complete or dishwasher displays a drain error code
⚠️ Visible water leaking from beneath the dishwasher near the pump area
🔍 Diagnostic tip: Set your multimeter to the continuity setting and probe the pump motor terminals. No continuity = failed motor; replace the pump. Drain pumps are not repairable — replacement is the only fix. Also inspect the drain hose and filter basket for blockages before ordering; a clogged filter can mimic a bad pump.
