Possible Causes
Stuck drain pump relay on control board, Faulty water level sensor, Control board software glitch, Shorted wiring to pump
How to Fix / Troubleshooting
Safety: Unplug the unit before inspection.
Basic checks:
- Inspect the wiring harness to the drain pump for signs of rubbing or shorting to the cabinet.
- Disconnect the pump connector and check if the pump stops running (if it was stuck on). If it continues, the issue is on the board.
- Power-cycle the unit for 5–10 minutes to reset the control.
- If the pump only runs when commanded but the code persists, test the water level sensor or float switch and replace if faulty.
- If the pump runs continuously whenever power is applied, the control board drain relay is likely stuck and the board must be replaced.
