LG Washer Error Code PF — Power Failure
What this means
The PF error code means the LG washer lost electrical power during an active cycle. This can be caused by a momentary power outage, a tripped circuit breaker, a loose power cord connection, or an unstable electrical outlet. After a PF error, the washer pauses the cycle so you can choose to restart.
Step-by-step fix
3 stepsRestart the interrupted cycle
Press the Start/Pause button to resume the cycle from where it was interrupted. The washer will attempt to continue from the point of the power loss.
If you prefer to start fresh, press Power to cancel, then select a new cycle and press Start.
Check the electrical connections
Ensure the power cord is firmly plugged into the wall outlet. Check that the outlet is not controlled by a switch that may have been accidentally turned off. Try plugging another device into the outlet to verify it's working.
LG washers should be plugged directly into a dedicated wall outlet — never use an extension cord.
Check the circuit breaker
Go to your electrical panel and check if the breaker for the laundry room has tripped. Reset it by flipping it fully to OFF and then back to ON. If it trips again immediately, there may be an electrical issue requiring an electrician.
Washers typically require a dedicated 20-amp circuit. Sharing with other high-draw appliances can cause trips.
When to call a professional
If the PF error recurs frequently without a known power outage, call an electrician to check the circuit and outlet. If the washer itself is causing breaker trips, a service technician should inspect it for internal shorts.
