LG Dishwasher Error Code PF

PF stands for Power Failure on an LG dishwasher. It means the appliance detected an interruption in its power supply, most commonly from a household outage or a tripped breaker. The code is a protective notification, not a sign of internal damage. It displays for about 10 seconds after power is restored and a button is pressed, then clears automatically.

Yes, the PF code does not indicate any internal fault with the dishwasher, so it is safe to continue using the appliance after the code clears. Before restarting, check that no water is sitting in the tub from the interrupted cycle. If the tub is clear, simply select your cycle and start normally.

Most PF errors require no parts or service call at all since the code typically clears after a normal power disruption. If the issue is traced to a faulty wall outlet, electrical repair costs can range from $75 to $200 depending on your area. In rare cases where the control board is involved, board replacement can range from $150 to $400 including parts and labor.

Yes, the PF code clears on its own after approximately 10 seconds once power is restored and a button is pressed. You do not need to perform a manual reset. After the code clears, you can restart your wash cycle from the beginning since the previous cycle likely did not complete.

In most cases no repair is needed. Confirm that your home's power supply has been restored, check that the circuit breaker for the dishwasher has not tripped, and ensure the power cord is securely plugged into the outlet. If the PF code appears repeatedly without any obvious power event, inspect the outlet and cord for faults or have an electrician verify the circuit.
