LG Washing Machine Error Code PF

Not a faultReviewed November 2026Checked against manufacturer documentation

What this code means

PF: Power failure notice

PF simply reports that power was interrupted during the cycle. It is information, not a fault: most models let you press Start/Pause to resume where the cycle stopped.

Fix level

Not a fault

This is a status display, not a fault. No repair is needed.

Time to run the checks

About 15–30 minutes

For the 3 checks on this page — not a full repair.

You may need

No special tools

The checks below use basic household items only.

Parts that may be involved

None usually

Parts are model-specific; see the note below before ordering.

Common causes

Power outage or tripped breaker
Plug pulled or loose in the outlet
Voltage dip

What to check, in order

Safety first. Switch the machine off and unplug it before cleaning filters or moving hoses. Expect water to come out when you open a pump filter; keep a tray and towel ready. If you are not comfortable with any step, stop and call a technician.

Press Start/Pause to resume the cycle.
Check the outlet and breaker if PF appears without an outage.
Frequent PF with stable home power can indicate a board problem.

Clear the code and test

Fix what the checks above found first — a filter cleaned, a hose straightened, taps opened. Clearing the code without fixing the cause only brings it back.
Close the door, plug the machine back in and restore the water supply.
Run a short rinse and spin, or the shortest wash programme, and watch the stage where the code appeared before (filling, washing, draining or spinning).
If the cycle finishes with no code, the fault is cleared. If the code returns at the same stage, write down the code and that stage before calling a technician — it speeds up the diagnosis.

When to call a professional

This display is not a fault, so there is normally nothing to book. Call a technician only if the machine also behaves abnormally, or if any of these apply:

The code comes back after you have run the checks and a test cycle.
You smell burning, see sparks or scorch marks, or the breaker trips.
Water is leaking and you cannot stop it at the tap.
The fix needs panels opened beyond what your manual describes, or a part tested with a meter, and you are not set up for that.

When you call, give the brand, the code PF, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.
