Difficulty

Most people can clear this one at home with simple checks.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG PF

  1. Clear the code

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

  2. Check the circuit

    LG calls for a dedicated, grounded 120 V, 60 Hz circuit rated for at least 15 A. Do not run the dishwasher from an extension cord or power strip; if you are not sure how the circuit is set up, ask an electrician.

When to call a technician

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