LG Washer PF Error Code

PF identifies an interruption of power during a cycle. LG explains that the message can be part of the washer power-failure recovery system and is not necessarily a product defect.

Applies to LG front-load washers

What the washer detected

Detected condition

Power to the washer was interrupted during a cycle.

What may contribute

Possible causes

  • A power outage while a cycle was running.
  • The washer power plug being removed while a cycle was running.

Start conservatively

Safe preliminary checks

Work in order and stop whenever a step is not supported by the documentation for your model.

  1. Record the code, model, and circumstances

    • Photograph or write down PF and note whether a known outage or loss of power occurred during the cycle.
    • Confirm the full model number because recovery behavior and controls can differ.

  2. Understand the recovery message

    • LG says the power-failure recovery system remembers and resumes the work the machine was doing before power was lost.
    • A PF message following an interrupted cycle is not necessarily a product defect.

  3. Perform the documented recovery reset

    • Unplug the washer or switch off the circuit breaker that supplies power to it.
    • While the washer is without power, press and hold Start/Pause for five seconds.
    • Restore power and try to run a cycle once.

Actions not recommended

  • Do not open an electrical panel, outlet, washer panel, or other electrical enclosure to investigate PF.
  • Do not diagnose household wiring, voltage, the outlet, or utility power quality from PF alone.
  • Do not treat PF as proof that the washer or a specific component is defective.

When to stop and request service

  • PF persists after the documented power-recovery reset.
  • PF recurs without a known interruption and needs assessment by an appropriate qualified professional.
  • Any appliance or electrical-system inspection beyond the documented controls would be required.
