How to Fix LG WM4000HBA Washing Machine OE Error Code

Quick Diagnosis

The OE error code indicates that the washing machine was unable to drain water during the cycle. This is usually caused by a clogged drain pump filter, a kinked drain hose, or a malfunctioning drain pump motor.

Step-by-Step Resolution

  1. 1

    Unplug the washing machine from the wall outlet.

  2. 2

    Open the small access cover on the front-bottom corner of the washer and pull out the emergency drain tube.

  3. 3

    Remove the tube's plug and drain all standing water into a shallow container or bowl.

  4. 4

    Turn the drain pump filter counter-clockwise, pull it out, and wash away any lint, buttons, or debris.

  5. 5

    Check the drain hose behind the washer for kinks, pinches, or a high-loop height exceeding 96 inches.

  6. 6

    Reassemble the filter and drain tube, plug the washer back in, and run a 'Spin Only' cycle to verify drainage.

Alternative Causes & Edge Cases

  • Applies to Sears Kenmore front-load washing machines built on the LG platform.
  • A frozen drain line or water supply line in unheated laundry rooms will prevent proper drainage and cause the OE error.
