How to fix LG PF

  1. Clear the code

    Press any key on the panel. The display can take about 10 seconds to clear; then restart your cycle.

  2. Check the circuit

    LG wants a dedicated, grounded 120 V, 60 Hz circuit rated for at least 15 A. Don't run it from an extension cord or power strip. If you're not sure how the circuit is wired, ask an electrician.

When to call a technician

If PF keeps appearing without any power outages, have an electrician check the circuit and outlet.
