Match the symptom, then work through the safe checks.
1. What best matches what you observe?
2. Complete only the checks that are safe for you.
Show stop conditions
- A hose, fitting, tub, or pump area leaks after thawing
- The washer is outdoors or in a wet electrical environment
- An open flame, heat gun, boiling water, or internal panel removal would be required
Likely causes
- The drain hose or pump path is frozen
- The inlet hose, faucet, or supply path is frozen
- The washer's internal temperature is below its operating threshold
- Ice remains after only the visible hose has thawed
Quick checks, in order
Move the washer into safe above-freezing conditions
Allow natural thawing when possible and do not operate the washer while water paths remain frozen.
Remove laundry and retained water safely
Follow the model instructions and prepare for water before opening any user-accessible drain point.
Use warm water, not boiling water or flame
LG guidance for supported models uses approximately 50–60°C warm water to thaw the tub and warm towels around frozen hoses.
Stop if hoses are split or water reaches electrical areas
Freezing can damage hoses and fittings; leaks must be repaired before the washer is powered again.
What happens after the washer warms?
Run a supervised rinse or spin test and inspect every visible hose connection for leaks.
The drain hose or pump path may still be frozen or restricted.
The faucet, inlet hose, or water-supply path may still be frozen.
Verify the complete model and arrange temperature-sensing or control diagnosis.
Stop and get qualified help when
- A hose, fitting, tub, or pump area leaks after thawing
- The washer is outdoors or in a wet electrical environment
- An open flame, heat gun, boiling water, or internal panel removal would be required

Frequently asked questions
What does FF mean on an LG washing machine?
FF means Freeze Failure or freeze detection on supported LG washers. Water in the inlet or drain path may be frozen.
Can I use boiling water to clear LG FF?
No. LG guidance uses warm water around 50–60°C for supported procedures. Boiling water, flame, or uncontrolled heat can damage parts and create injury risks.
Why does LG FF change to OE or IE?
OE points toward a remaining frozen or restricted drain path, while IE points toward the faucet or inlet-supply path.
