LG Washing Machines OE Error Code (Drain Error): How to Fix It Yourself

The OE error on your LG washer means the water is not draining out properly. The most common cause is something stuck in the drain pump filter — coins, bobby pins, and small socks are the usual culprits. Cleaning the filter takes about 15 minutes and fixes this problem most of the time.

⚡ Difficulty: Easy⏱ 15-30 minutes💰 Parts cost: $0–$30🔧 Tools: Flathead screwdriver, Towels or shallow pan, Pliers

⚠️ Safety First

  • Unplug the washing machine before doing anything.
  • Have plenty of towels ready — water will spill when you open the filter.
  • Do not tip the machine while it is full of water.

Step-by-Step Repair

  1. 1

    Unplug the washer

    Pull the power cord from the wall outlet. Safety first — never work on a machine that is plugged in.

  2. 2

    Locate the drain pump filter

    On LG front-load washers, look at the bottom-left corner of the front panel. There is a small access door. Open it with a flathead screwdriver or by pressing the tab. You will see a small hose and a round filter cap.

  3. 3

    Drain remaining water

    Pull out the small emergency drain hose (next to the filter cap). Place the end in a shallow pan or bowl and remove the plug. Let the water drain out slowly. This can take a few minutes if the tub is full.

  4. 4

    Remove and clean the filter

    Once the water has drained, turn the round filter cap counter-clockwise and pull it out. Remove any debris — coins, hair, lint, or small clothing items. Rinse the filter under running water.

  5. 5

    Check the drain hose

    Look at the drain hose at the back of the machine. Make sure it is not kinked, pinched, or clogged. Also check where it connects to your standpipe or sink — that connection can get clogged too.

  6. 6

    Reassemble and test

    Put the filter back in (turn clockwise until snug), plug the small drain hose back in, and close the access door. Plug the washer in and run a quick rinse-and-spin cycle. The OE error should be cleared.

If That Didn't Work

  • Kinked drain hose behind the washer
  • Clogged standpipe or home plumbing issue
  • Failed drain pump motor
  • Faulty water level pressure switch

When to Call a Professional

If the filter is clean and the hose is not kinked, the drain pump motor itself may have failed. You can test it by listening — if you hear a humming noise but no water drains, the pump is likely stuck or burned out. Replacing the pump is a Medium job. A tech will charge $120–$200 including the part.
