LG Washing Machine Error Code FF
FF appears when freezing temperatures have frozen the tub, hoses or drain path so the washer cannot operate. It is a winter condition, not a broken part, unless something cracked.
Common causes
- Inlet or drain hose frozen
- Water frozen in the tub or pump
- Machine installed in an unheated space
What to check, in order
- Pour warm (not boiling) water into the drum and let it sit to thaw the tub and drain hose.
- Thaw hoses gently and check for splits afterwards.
- Restart once everything moves freely, and watch the first cycle for leaks.
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
Most cases are solved by the checks above. Book a technician 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 FF, your model number (on a label inside the door or on the back) and the checks you already ran. It shortens the visit.

Parts are model-specific. Find your model number first — usually on a label inside the door, on the door frame or on the back — and match the part to that number before ordering.
