Drum remains full of water after cycle ends; washer stops mid-cycle. The failed pump motor cannot build enough pressure to expel water through the drain hose.
Control board detects drain time has exceeded 8 minutes without reaching the pressure-sensor reset level, shutting off the pump. Replacing the drain pump clears this fault.
Motor windings are energised but the impeller is seized or broken, causing a loud hum with no water movement during the drain phase of the cycle.
Cracked pump housing or deteriorated hose-port seals allow wastewater to escape onto the floor during the drain cycle.
Residual water weight sensed by pressure switch prevents the drum from entering the spin sequence; draining the tub fully by replacing the pump restores normal spin operation.
💡 Pro Tip: How to Confirm Your Drain Pump Has Failed
Your part is likely the culprit if you notice any of the following:
⚠️ Washer stops mid-cycle with standing water in the drum and will not drain
⚠️ Error codes E01 / F09 displayed — indicates drain time exceeded 8 minutes
⚠️ Loud humming or buzzing sound during the drain phase but no water movement
⚠️ Water leaking from underneath the machine near the pump housing
Before replacing the pump, first check the drain hose and coin-trap filter for clogs. If both are clear and the washer still hums without draining, the pump motor is almost certainly seized — replace it with this part.
