If your LG Washer is showing error code PF, the machine experienced a power failure or power interruption during a wash cycle. Error PF is a power fault notification, not a mechanical failure — it means the washer lost mains power mid-cycle and is alerting you when power was restored. Here is what to do about LG Washer error PF.

⚡ Quick Fix – Top 3 Steps

1. Press Start/Pause to resume the cycle. After a power interruption, many LG Washer models allow the cycle to resume from where it was interrupted. Press Start or Start/Pause and the washer will attempt to continue the cycle. This is the simplest resolution if the power has now been restored normally.
2. Press Power Off, then restart a new cycle. If the cycle cannot resume or the load has been sitting for a long time, press Power to turn the washer off, then select a fresh cycle and press Start. The PF display is a notification that is cleared when a new cycle begins.
3. Check your home’s electrical supply and outlet. If PF appeared during normal operation without an obvious power cut, check the wall outlet the washer is plugged into. A loose plug, tripped circuit breaker, or faulty outlet can cause intermittent power loss that triggers PF. Ensure the washer is plugged directly into a wall outlet — not an extension cord — and that the outlet is receiving consistent power.

What Does LG Washer Error PF Mean?

Error PF stands for Power Failure. Unlike most LG Washer error codes that indicate a component fault, PF is informational — it tells you that the washer’s cycle was interrupted because mains power was lost. This can happen during a household power outage, if someone unplugged the machine accidentally, or if a circuit breaker tripped. When power returns, the washer displays PF to inform you of what happened rather than continuing the cycle automatically.

PF does not indicate any damage to the washer and does not require a repair. If PF is appearing repeatedly without any obvious power interruption, it may indicate an intermittent electrical supply problem — either at the wall outlet, the power cord, or the washer’s internal power supply board.

Common Causes of LG Washer Error PF

• Household power outage: A brief or extended power cut during a cycle will trigger PF when power is restored.
• Tripped circuit breaker: The washer’s circuit breaker has tripped, cutting power and then restoring it when reset.
• Loose power cord or plug: A loose connection at the wall outlet causes intermittent power loss.
• Faulty wall outlet: The outlet supplying power to the washer has a loose internal connection and drops power intermittently.
• Extension cord use: LG recommends against using extension cords — they can cause voltage drops that trigger PF.
• Damaged power cord: A frayed or damaged power cord can cause intermittent power loss to the washer.

How to Clear LG Washer Error PF

To clear PF, simply press Start/Pause to attempt to resume the interrupted cycle, or press Power to clear the notification and then select a new cycle. No repair is required unless PF is appearing repeatedly without any explanation, in which case check the power supply as described above.

If PF appears repeatedly, plug the washer into a different wall outlet to test whether the original outlet is faulty. If PF stops appearing on a different outlet, have an electrician inspect the original outlet. If PF continues on a different outlet, check the power cord for damage and consider having the washer’s internal power board inspected.
