Possible Causes
Shorted drain pump, Shorted triac on main PCB, Wiring short between pump and PCB, Moisture on PCB causing tracking
How to Fix / Troubleshooting
Safety first: Unplug the washer. Do not continue to run the machine with this error, as it may damage the PCB further.
Step-by-step checks:
- Test drain pump: Disconnect the pump and measure coil resistance. If it is very low (near short) or shows signs of burning, replace the pump.
- Inspect wiring: Check the harness from the PCB to the pump for insulation damage or shorts to chassis. Repair as needed.
- Inspect PCB triac: Access the main PCB and look for a burnt or cracked triac in the pump control area. If damaged, the PCB must be replaced.
- Replace components: Replace the pump if faulty, and the PCB if the triac or tracks are damaged.
