LG Dishwasher Error Code PF — Power Failure
What this means
The PF error code means the LG dishwasher experienced a power interruption during an active cycle. This is usually caused by a power outage, a tripped breaker, or a loose electrical connection. After power is restored, the dishwasher displays PF and waits for you to restart.
Step-by-step fix
3 stepsRestart the cycle
Press the Power button, select your desired cycle, and press Start. Some LG dishwashers will allow you to resume the interrupted cycle by simply pressing Start.
Check the circuit breaker
Go to the electrical panel and verify the dishwasher's circuit breaker is ON. If it tripped, flip it fully OFF and then back ON.
If the breaker trips when the dishwasher runs, there may be an electrical issue with the appliance or circuit.
Verify the electrical connection
If the dishwasher is plug-connected (rather than hardwired), ensure the plug is fully inserted in the outlet under the sink. Check that the outlet is functioning by testing with another device.
When to call a professional
If PF errors occur frequently without a known power outage, call an electrician to inspect the circuit. If the dishwasher itself is tripping the breaker, a technician should inspect for internal electrical faults.
