Dishwasher displays E24 (drainage problem) or E25 (drain pump blocked) error and stops mid-cycle or fails to complete the drain phase.
Water remains pooled at the bottom of the dishwasher tub after the cycle ends, indicating the drain pump motor is not running or the impeller has failed.
A loud grinding, humming, or bearing noise is heard during the drain phase, caused by worn bearings or a failing pump motor that can no longer spin quietly.
The dishwasher completes the wash cycle but water does not drain out. The drain pump motor receives power but fails to rotate or move water through the drain hose.
The dishwasher takes much longer than normal to drain, or leaves a small puddle beyond the sump area, indicating a weak or partially failing drain pump impeller.
💡 Pro Tip: How to Confirm Your Drain Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ E24 or E25 error code displayed on the control panel
⚠️ Standing water left in the tub after a completed cycle
⚠️ Drain pump hums but does not move water out
⚠️ Loud grinding or bearing noise during the drain phase
🔍 Diagnostic tip: Set your multimeter to continuity mode and probe the drain pump motor terminals. No continuity = confirmed motor failure. Also check that the impeller spins freely — a seized or separated impeller from the driveshaft requires full pump replacement. Drain pumps are not repairable; replace the full assembly when defective.
