LG Error Codes

LG appliances flag problems with a short code on the display instead of a plain message. Find your appliance type below, match the code, and see what it usually means and whether it’s a quick fix or a job for a technician. Note: exact codes can vary slightly by model year and platform (top-load vs. front-load, French door vs. side-by-side) — if yours isn’t listed, call us and read us the display and we’ll identify it.
