Possible Causes

Blocked drain pump filter, Foreign object in drain pump impeller, Blocked drain hose, Failed drain pump motor

How to Fix / Troubleshooting

Safety: Unplug the washer. Water may spill when opening the filter; keep towels and a shallow tray ready.

  • Access the pump filter: Open the small service flap at the bottom front of the machine. Place a tray under the filter cap.
  • Drain residual water: If fitted, use the emergency drain hose to empty water into the tray. Then slowly unscrew the pump filter cap.
  • Clean the filter: Remove lint, coins, buttons, and other debris from the filter and pump cavity. Check that the impeller turns freely by hand.
  • Check drain hose: Inspect the drain hose at the rear for kinks or blockages. Detach from the standpipe or sink trap and flush through with water.
  • Test the pump: With the machine reassembled and plugged in, run a drain/spin program. If you hear no pump noise or it hums but does not turn, the pump motor is likely defective and should be replaced.
  • Replace pump if required: Access from the front bottom or rear (model dependent). Remove mounting screws, disconnect wiring and hoses, fit the new pump, and ensure all clamps are tight to prevent leaks.
