Steps

  1. Pause the cycle and turn the washer off before opening the drain pump access area.
  2. Drain remaining water through the small drain hose into a shallow pan.
  3. Remove the drain pump filter, clear debris, and reinstall it fully.
  4. Check the drain hose for kinks, clogs, height problems, or being pushed too far into the standpipe.

  6. If OE returns after these checks, use LG support or schedule service.
