LG Washer FF Error Code: What It Means & How to Fix It

FF = Washer frozen. FF means water in the washer, usually in the hoses or drain pump, has frozen. It shows up in garages and unheated laundry rooms during cold snaps.

Can you fix it yourself? Yes

Check your model: Error codes can mean different things on different LG models. Find your model number (usually on a sticker inside the door or lid, or on the back) and confirm the code in your user manual.

Safety first: Unplug the appliance (or switch off its breaker) before you remove panels, filters or hoses. Turn off the water supply valves before you disconnect any hose, and keep a towel and shallow pan handy. Never work on wiring, gas lines or sealed refrigerator systems yourself.

Is the washer somewhere that drops below freezing?

How to fix LG Washer FF

Unplug the washer.
Following LG's guidance, add warm (not boiling) water to the drum to help thaw the drain hose and pump.
Wrap the supply hoses in warm, wet towels to defrost them.
Once water drains and flows freely, plug back in and run a short cycle.

Still showing FF?

If it still won't fill or drain once it's thawed, check for a cracked hose and schedule service if needed.

Repair or replace?

If the appliance is under warranty, call LG first, since a repair may be free. Out of warranty, a common rule of thumb is to compare the repair quote with the cost of a new unit and the appliance's age before deciding.
