FF is a cold-weather protection condition. The safe remedy is gradual warming and leak inspection, not forcing a cycle or applying concentrated heat to plastic parts.
LG washer FF code: LG defines FF as Freeze Failure. The code can appear when the washer’s internal temperature falls below about 1°C and water in the inlet or drain path freezes; controls may remain disabled until the appliance warms above about 4°C.
Why the washer shows it
Thaw a cold-affected LG washer safely without damaging hoses or components.
What to do next
- Switch the washer off and close both water-supply valves.
- Warm the laundry area gradually to a safe room temperature. Do not use an open flame, heat gun, or boiling water.
- Inspect visible inlet and drain hoses for bulging, cracking, or split fittings as they thaw.
- Place towels where a thawed connection could leak and keep electrical connections dry.
- After the appliance and hoses have fully warmed, open the valves slowly and watch for leakage before restoring power.
Likely fault categories
- The washer or its hoses were exposed to near-freezing or freezing temperatures.
- Standing water froze in an inlet hose, drain hose, pump path, or internal water component.
- A cold room, exterior wall, unheated garage, or prolonged outage allowed the appliance temperature to fall.
What the result does—and does not—prove
Frozen water expands and can damage hoses and plastic water parts. A cleared code does not guarantee that no crack developed.
Do not run the pump against ice and do not pour very hot water into the drum or dispenser.
If a hose is damaged or water appears beneath the cabinet, keep the supply closed and arrange service.
Observe the washer rather than guessing a part: note water level, basket movement, sound, cycle stage, and whether the display changes. If the same warning returns under ordinary conditions, stop the retry loop. The full code, model number, and these observations are the most useful handoff to qualified service.
Check the exact model before going further
Cold-weather and winterizing instructions vary. Follow the exact LG manual, particularly before storage or use in an intermittently heated space.
Call for qualified help when
Seek service when FF remains after full warming, a hose or fitting leaks, the pump makes abnormal noise, or water is present under the cabinet.
Before contacting support, photograph the full display and record the model number, cycle, selected options, and the last completed stage. Include which external checks were performed and whether water remains in the drum.

For the next relevant check, see washer not filling with water. Useful if the thawed washer still cannot receive water.
For the next relevant check, see washer won’t drain. Supports drain-path checks if residual ice or damage prevents draining.
Frequently asked questions
Can I use a heat gun to clear FF?
No. Warm the room gradually and avoid concentrated heat, flame, or boiling water.
Can I use the washer as soon as FF disappears?
First inspect thawed hoses and connections for leaks and confirm the appliance is fully warmed.
