PF records a power interruption. Before pressing Start, determine whether the whole home lost power, the plug was disturbed, or the washer alone stopped, because repeated interruptions need a different response than a one-time outage.
LG washer PF message: LG says PF indicates that power was cut during operation. On supported models, the power-failure recovery system can remember the interrupted work and allow the cycle to continue; the message alone is not proof of a washer defect.
What this display is telling you
Understand an LG power-failure message and resume safely after checking the supply.
A safe response, in order
- Confirm that household power is stable and other appliances on the circuit are operating normally.
- Inspect the washer plug and cord from the outside for looseness, damage, heat, or discoloration. Do not use a damaged connection.
- Check the breaker once. If it has tripped, do not repeatedly reset it when it trips again.
- If PF followed a known outage or unplugging and no damage is visible, press Start/Pause as the model manual directs.
- Watch the resumed cycle long enough to confirm that power remains stable.
What can sit behind the code
- A utility outage or brief voltage interruption.
- The washer was unplugged or its breaker was switched off during a cycle.
- A loose receptacle, damaged cord, overloaded circuit, or internal electrical problem when PF repeats without a known outage.
Important distinctions
PF is not a request to perform a factory reset. It identifies interrupted power and recovery behavior.
Do not use an extension cord or power strip to work around a receptacle problem.
A washer that repeatedly loses power, trips a breaker, or produces heat or odor should remain disconnected until inspected.
If the display clears after the external condition is corrected and does not return, monitor the next full cycle. A code that comes back at the same stage is stronger evidence of a recurring fault than a single interrupted cycle. Stop immediately when the observation includes uncontrolled water, abnormal heat, an electrical smell, a breaker trip, or violent movement.
Check the exact model before going further
Recovery behavior and whether a cycle resumes automatically vary by LG model. Use the exact owner’s manual before assuming the previous program will continue.
The point to stop troubleshooting
Service or a qualified electrical check is appropriate when PF recurs without a household outage, the plug or outlet heats, the breaker trips, or the appliance will not stay powered.
Have the appliance model information ready. A short note describing what entered, moved, drained, heated, or locked immediately before the code is more useful than a guessed component name.

Frequently asked questions
Is LG PF always a washer defect?
No. LG says it can simply record a power outage or unplugging during a cycle.
Why does PF keep returning?
Repeated PF without a known outage can indicate an unstable supply or appliance electrical issue that needs inspection.
