What Does Error PF Mean?
The LG washing machine PF error code indicates a power failure, typically triggered by a sudden loss of power or unplugging during a cycle. This results in the machine pausing and displaying the PF code, entering a power‑failure recovery mode. To resolve the issue, ensure the washer is properly connected to a grounded outlet and check for any electrical interruptions.
Common Symptoms:
- PF appears on display after a sudden loss of power or plug removal mid‑cycle
- Machine pauses or does not complete the cycle until power is restored
Possible Causes
- Temporary power interruption (outage or plug removal) (high)
How to Fix Error PF
DIY Fix Basic Reset and Power Check
- Turn the washer off and unplug it from the wall outlet.
- Wait 1–5 minutes to allow power to reset.
- Ensure the washer is plugged directly into a properly grounded outlet.
- Check that other appliances work on the same outlet to verify power supply.
DIY Fix Check Household Electrical Supply
- Inspect the circuit breaker panel for a tripped breaker and reset if needed.
- Avoid using extension cords; plug washer directly into a wall socket.
- Use a surge protector or voltage stabilizer to protect against fluctuations.
Technician Only Inspect Internal Power Connections & Control Board
- Disconnect power and remove the back panel.
- Inspect power cord connection and internal wiring for loose or damaged connectors.
- Test control board power circuits if PF persists despite stable external power.
Parts needed: multimeter, screwdrivers, possible replacement control board or wiring harness
- PF persists after stable power and reset attempts
- Signs of electrical damage, burning smell, or frequent tripped breakers
