Frequently Asked Questions
How do I reset an LG washer after an error code?
Press START/PAUSE to clear most codes and return the machine to PAUSE; if not cleared, the washer shuts off automatically after a few minutes and blinks the code. See the code's own page for the underlying fix.
How do I run LG's built-in diagnostic test modes?
Several LG washer service manuals include Quick Test Mode and numbered Testmodes (e.g. Testmode 3 for the inlet valve) accessed via specific button combinations during setup — covered on the relevant code's page where applicable.
What's the difference between UE and LE?
UE is a load-balance/leveling issue. LE is a motor/hall-sensor electrical fault — a completely different kind of problem despite both stopping the spin cycle.
