How to Fix / Troubleshooting
Safety first: Unplug the machine and prepare for possible water spillage when accessing the pump.
- Inspect pump and wiring: Access the drain pump from the front lower panel or rear. Check for burnt connectors or damaged insulation.
- Test pump motor (qualified persons): Measure resistance across the pump terminals. Replace the pump if the coil is shorted or open.
- Check for leaks: Ensure no hoses are dripping onto the control board or pump area.
- Control board evaluation: If the pump is good and wiring intact, the pump triac on the main PCB may be faulty. Board replacement is typically required and should be done by a technician.
