LG Washer OE Error Code — Drain Not Draining Fix
The LG OE error (Output Error — referring to water output/drainage) means the washer failed to drain within the expected time. On LG front-loaders, the number one cause is a clogged pump filter — a 5-minute cleaning job. On top-loaders, the drain hose position is the most common culprit. Work through the filter and hose checks before assuming pump failure.

Common Symptoms
- OE error code on the display
- Standing water left in the drum after a cycle
- Washer pauses mid-cycle and won't advance
- Slow drain — takes much longer than normal
- Pump noise but water level stays high
Most Likely Causes
- 1
Clogged Pump Filter (Front-Loaders, Most Common)
LG front-loaders have a pump filter (debris filter) behind the small access door at the bottom front of the machine. Coins, lint, and small items collect here and block drainage. This is responsible for the vast majority of OE errors on front-load LG washers.
- 2
Incorrect Drain Hose Height
The drain hose must enter the standpipe at a height between 18–96 inches from the floor. If the hose end is too low (below 18 inches), gravity siphons water back into the drum. If it's too high (above 96 inches), the pump can't push water up to drain.
- 3
Kinked Drain Hose
A tight bend in the drain hose — often from the machine being pushed too close to the wall — restricts flow. Pull the machine out and check the entire hose path for kinks.
- 4
Faulty Drain Pump
If the filter is clean, hose is properly positioned, and the standpipe drains freely, the pump motor may have failed. You'll typically hear a hum from the pump area but see no water movement in the drain hose.

Quick DIY Checks
Unplug the washer before opening the pump filter access panel. Have towels and a shallow pan ready — a full drum can release several gallons of water when the filter cap is removed.
- 1Unplug the washer. Locate the access panel at the bottom front of the machine (on front-loaders) — it usually unclips or has one screw. Place towels down and have a shallow pan ready. Slowly turn the pump filter cap counterclockwise to drain water, then remove and rinse the filter thoroughly.
- 2With the filter removed, shine a flashlight into the pump port and check for debris. Spin the pump impeller by hand — it should turn freely. Reinstall the clean filter and tighten the cap firmly.
- 3Check the drain hose position: the end of the drain hose should enter the standpipe or utility sink between 18 and 96 inches from the floor. Use a zip tie or hose hook to secure the hose at the correct height if it's positioned incorrectly.

Try Pro — $7.99/mo- 4Run a Spin-Only or Drain & Spin cycle to test. If the OE error is gone and the drum drains, the filter was the problem. If the error returns, continue to step 5.
- 5Test the pump: disconnect the drain hose at the machine end and hold it over a bucket. Run a cycle — if water flows under pressure into the bucket, the pump works and the problem is downstream (standpipe, hose height, or a clog further along the hose). If only a trickle or nothing comes out, the pump is faulty.

Frequently Asked Questions
- How do I clean the LG washer pump filter?
- Open the small access door at the bottom front of the machine. Place a shallow pan and towels under the filter area. Slowly turn the filter cap counterclockwise — water will drain out. Once the water flow stops, remove the cap completely and pull out the filter. Rinse it under running water and remove any debris. Reinstall the filter, tighten the cap clockwise until it stops, and close the access panel. LG recommends cleaning this filter every month.
- How high should my LG washer drain hose be?
- The drain hose end should be between 18 and 96 inches (1.5 and 8 feet) above the floor. LG recommends 24–36 inches as the optimal range for most installations. If the hose is below 18 inches, water will siphon back into the drum. Use the U-shaped plastic hose guide (included with most LG washers) to secure the hose at the correct height on the standpipe.
- My LG washer shows OE but I can hear the pump running — what does that mean?
- If the pump is audibly running but water isn't draining, the most common cause is a blocked filter or a clog in the drain hose downstream of the pump. The pump itself is likely working. Clean the filter, check the hose for kinks, and verify the standpipe drain is flowing freely. If the hose and standpipe are clear and the filter is clean, the pump impeller may be spinning but broken internally — inspect through the filter port.
