Causes of the PF error code:

• Power outage: 
  • An external power outage is the most common reason for the PF error.
• Loose power cord: 
  • If the power cord connecting the machine to the outlet is loose or damaged, it can interrupt the power supply.
• Internal malfunction: 
  • In rare cases, a malfunction within the machine itself can disrupt its power connection, leading to the PF error.

Troubleshooting the PF error code in LG Washing Machine

1. Turn off and unplug the washing machine.
2. Wait for power to be restored: 
   • If the PF error appeared due to a power outage, wait for the power to come back on before proceeding.
3. Reconnect the power cord: 
   • Ensure the cord is securely plugged into both the outlet and the machine.
4. Restart the washing cycle: 
   • Once the power is back on, try restarting the wash cycle from the beginning.
5. Check for additional issues: 
   • If the PF error persists even after restarting, check for any other symptoms like leaks, unusual sounds, or burning smells. These could indicate a more serious issue requiring professional attention.

Prevention tips:

• Use a surge protector: Plugging your washing machine into a surge protector can help protect it from sudden power surges and outages.
• Regularly inspect the power cord: Check the cord for any damage or wear and tear and replace it if necessary.
• Avoid overloading the machine: Overloading can put extra strain on the electrical components and potentially lead to power-related issues.

Keep in mind:

• While the PF error often signifies a simple power interruption, it's important to be mindful of any additional symptoms to rule out other potential issues.
• If the error persists after trying the troubleshooting steps, it's best to contact LG support or a qualified appliance repair technician for further assistance.

I hope this information helps you resolve the PF error on your LG washing machine.
