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.

How to Fix Error PF

DIY Fix Basic Reset and Power Check

  1. Turn the washer off and unplug it from the wall outlet.
  2. Wait 1–5 minutes to allow power to reset.
  3. Ensure the washer is plugged directly into a properly grounded outlet.
  4. Check that other appliances work on the same outlet to verify power supply.
