Frequently Asked Questions

Common questions about LG UE error

The UE error appears when the LG WM3900HWA detects that the laundry load is unevenly balanced, which can cause excessive vibration during the spin cycle. It is most common when washing a single bulky item. Redistributing the load and adding a few towels for balance usually clears the error.

Add two or three bath towels alongside the comforter. A single heavy item concentrates weight on one side of the drum and almost always triggers the UE error. The added towels help distribute the weight evenly during the high-speed spin.
