How to Fix PF (LG/GE Appliance)
Quick Answer
The 'PF' error code on an LG or GE appliance indicates a Power Failure. This typically means the appliance experienced a temporary interruption in its electrical supply. The fastest fix is often to reset the appliance by unplugging it for a short period.
What Causes This Error
- Temporary power outage or brownout in the home or area.
- Loose or faulty electrical outlet or power cord connection.
- Tripped circuit breaker or blown fuse supplying power to the appliance.
- Internal power supply issue within the appliance (less common).
- Fluctuations in household voltage.
- Appliance was unplugged and then re-plugged, triggering the code.
Step-by-Step Fixes
1Reset the Appliance to Clear the PF Error
- Locate the appliance's power cord and unplug it from the electrical outlet.
- Wait for a minimum of 5 minutes to allow any residual electrical charge to dissipate and the internal system to fully reset.
- Plug the power cord firmly back into the electrical outlet.
- Turn on the appliance and observe if the 'PF' error code has cleared. If the error persists, proceed to the next fix.
2Check the Circuit Breaker and Electrical Outlet
- Go to your home's main electrical service panel (breaker box).
- Locate the circuit breaker labeled for the appliance or the kitchen/laundry area. It may be in the 'OFF' or middle position.
- If the breaker is tripped (in the middle position), firmly push it to the 'OFF' position, then immediately push it to the 'ON' position.
- If the breaker was already in the 'ON' position, cycle it 'OFF' then 'ON' to perform a hard reset.
- Return to the appliance and verify that it has power and the 'PF' error is no longer displayed. Ensure the appliance's power cord is securely plugged into a functioning outlet.
3Inspect the Power Cord and Wall Outlet
- Carefully unplug the appliance from the wall outlet.
- Examine the appliance's power cord for any visible damage, such as cuts, frayed wires, or bent prongs.
- Inspect the wall outlet for any signs of damage, burn marks, or loose components. If the outlet appears damaged, do not use it.
- If possible, plug a different small appliance (e.g., a lamp or phone charger) into the same outlet to confirm it is supplying power.
- If the power cord or outlet is damaged, arrange for a qualified electrician or appliance technician to inspect and repair or replace the faulty component. Do not attempt to use a damaged cord or outlet.

Test for Voltage Fluctuations
- Acquire a multimeter capable of measuring AC voltage.
- With the appliance unplugged, carefully insert the multimeter probes into the slots of the electrical outlet that powers the appliance.
- Read the voltage displayed on the multimeter. The reading should be approximately 120V for standard outlets or 240V for larger appliances requiring a dedicated circuit.
- Observe the voltage reading over a short period (e.g., 30 seconds) to detect any significant fluctuations. Readings consistently outside of a 10% tolerance (e.g., below 108V or above 132V for a 120V outlet) may indicate a household wiring issue or external power supply problem.
- If unstable or incorrect voltage is detected, contact a licensed electrician to diagnose and resolve the electrical supply issue in your home.
Frequently Asked Questions
What does 'PF' mean on my LG or GE appliance?
The 'PF' error code stands for Power Failure. It indicates that the appliance experienced an interruption in its electrical power supply, which could be due to a brief power outage, a tripped circuit breaker, or the appliance being unplugged and re-plugged.
Why does my appliance show 'PF' even after a brief power flicker?
Modern appliances often have sensitive electronic controls. Even a very brief power flicker, brownout, or voltage dip can be interpreted as a power failure by the appliance's system, triggering the 'PF' code. The appliance logs this event to inform the user.
Is the 'PF' error code dangerous?
The 'PF' error code itself is not inherently dangerous; it's an informational code. However, if the underlying cause is a faulty electrical outlet, damaged power cord, or persistent electrical issues in your home, those conditions could pose a safety risk. Address the cause of the power failure promptly.
Will the 'PF' error clear itself?
In most cases, the 'PF' error will not clear itself automatically. It typically requires a manual reset of the appliance, such as unplugging it for a few minutes or cycling the circuit breaker, to clear the code and restore normal operation.
When should I call for professional service for a 'PF' error?
If you have tried resetting the appliance, checking the circuit breaker, and inspecting the power cord and outlet, but the 'PF' error persists or reappears frequently, it is advisable to contact a qualified appliance technician or a licensed electrician. This could indicate an internal component failure within the appliance or a more complex electrical issue in your home's wiring.
