LG WM4000HBA OE error code

Error code: OE

OE points to a washer drain problem: the washer is not draining normally or detects that water remains when it should be gone.

Common causes

Fix steps

  1. Turn the washer off before checking the drain area.
  2. Drain remaining water through the small drain hose if needed.
  3. Remove and clean the drain pump filter, then reinstall it securely.
  4. Check the drain hose for kinks, clogs, or incorrect standpipe placement.
  5. Run a short test cycle; request service if OE returns after the manual checks.
