Complete Guide on the PF Error Code on LG Washing Machines

Technically Reviewed by Oleg Chudnovski on Nov 01, 2025 | Written by Spark Service PRO Editorial Contributors

LG washing machines, known for their reliability and advanced features, may also occasionally encounter issues, and the PF error code is one of them. In this comprehensive guide, we'll explain when the PF error code occurs, identify the responsible components, and provide effective solutions to resolve this problem.

When does the PF Error Code Take Place

The PF error code, short for "Power Failure," typically occurs when there is an interruption in the power supply to the washing machine.

This can happen during a power outage or when the machine is unplugged while in operation. The PF error serves as an indicator that the machine has experienced a power disruption.

Parts Responsible for the PF Error Code

Understanding the components associated with the PF error is straightforward, as it primarily relates to the power supply. However, it's essential to note that sudden power fluctuations or interruptions can impact various internal components.

The main component is the power supply module, which is responsible for providing the necessary electricity to the washing machine. It may be affected directly by power surges or disruptions.

How to Solve PF Error

Resolving the PF error code involves a systematic approach. You should follow the next steps:

Verify Power Supply:

• Check the power supply to the washing machine. Ensure that the power cord is securely plugged into a functional power outlet. Confirm that there are no issues with the electrical circuit.

Check for Tripped Circuit Breaker:

• Examine the circuit breaker associated with the washing machine. If it has tripped, reset it to restore power. A tripped breaker is a common cause of power disruptions leading to the PF error.

Inspect the Power Cord:

• Examine the power cord for any visible damage or frayed wires. If the cord is compromised, it may need to be replaced. Ensure that the plug is securely inserted into the outlet.

Avoid Overloading Circuits:

• Overloading the electrical circuit by connecting multiple appliances to the same outlet can lead to power fluctuations. Dedicate a separate outlet for the washing machine to prevent PF errors.

Use a Surge Protector:

• Consider using a surge protector to safeguard the washing machine from power surges. Surge protectors can absorb excess voltage and prevent damage to sensitive electronic components.

Resume Operation:

• Once the power supply is stable, press the power button on the washing machine to resume regular operation. The PF error code should clear, allowing the machine to function without interruptions.

Contact an Electrician:

• If power-related issues persist, it may be necessary to consult with an electrician to inspect the wiring and electrical system in your home. A professional can identify and address potential electrical issues.

Final Conclusion

The PF error on LG washing machines is a straightforward indication of a power failure or disruption. By ensuring a stable power supply, checking the power cord and circuit breaker, and using protective measures such as surge protectors, you can effectively resolve the PF error, thereby maintaining the optimal performance and longevity of your LG appliance. Regular attention to power-related considerations enhances the reliability of washing machines.
