Possible Causes
Shorted drain pump, Water in base tray activating float switch, Damaged wiring to pump or float switch, Faulty leak sensor
How to Fix / Troubleshooting
Safety first: Unplug the washer and close water taps. Expect water in the base tray.
Steps to check and address E23:
- Check base tray: Tilt the machine slightly to see if water drains from the bottom. If so, dry the base tray thoroughly and locate the leak source (hoses, pump, tub).
- Inspect drain pump: Access the pump from the front or bottom. Check for signs of burning or water ingress into the motor. Test pump resistance with a multimeter; replace if shorted or open.
- Check float switch and wiring: Ensure the float switch in the base tray moves freely and its wiring is intact.
When to call a technician: If you cannot identify the leak or if the tub is cracked, professional repair or replacement of the appliance is advised.
