PF
LG Washing Machine
Severity: MinorWhat it means
LG washer PF error means a power failure interrupted the cycle mid-wash — LG's 'Power failure occurred' code.
The mains power went out (or had a brief brownout) during the cycle.
Press Start to resume the cycle from where it stopped — most LG washers remember the program.
Affected Models
- LG Front Load Washer
- LG Top Load Washer
- LG WashTower (combined washer + dryer)
- LG TurboWash Washer
- LG TwinWash Washer
Common Causes
- Mains power genuinely failed during the cycle
- Brief brownout dipped voltage below the washer's threshold
- Plug pulled or knocked out of the socket
- Circuit breaker tripped (overload or fault elsewhere)
- Loose mains cable to the washer
How to Fix It
-
Press Start to resume.
On most LG washers, pressing Start after PF resumes the interrupted cycle from where it stopped.
The washer remembers the program and finishes the wash. -
Check the mains plug.
Confirm the plug is firmly in the wall socket.
A loose plug rattled by spin vibration can disconnect briefly and trigger PF.
Push it home firmly. -
Check the breaker.
Look at the consumer unit / circuit breaker.
If a breaker has tripped, reset it and try the washer again.
If the breaker trips again immediately, there's a fault on the circuit and you need an electrician — don't keep resetting it. -
Move to a different outlet.
If PF appears regularly even without power outages, try the washer on a different mains outlet — ideally on a different circuit.
If it stops, the original outlet or circuit has a fault.
When to Call a Professional
PF rarely needs professional help — it's usually a one-off power blip.
Call an electrician only if PF appears repeatedly without obvious power outages, since that points at intermittent supply problems in the household wiring.
Frequently Asked Questions
Why does my LG washer show PF every time it spins?
Spin draws the highest current of the wash cycle, and that's when a marginal mains supply finally dips below the washer's voltage threshold.
If the washer runs through wash and rinse fine but PF appears at spin every time, the household wiring or breaker can't sustain the current draw.
An electrician can check the circuit; in the meantime, run the washer at off-peak times when other high-load appliances (kettle, electric heater, dishwasher) aren't running.
