Top 5 Causes of the OE Error on LG Washers

One common issue many users face is the OE error code, which indicates a drainage problem. Understanding what causes this error can help you decide whether it’s a quick fix or time to call a professional.

Here are the top 5 causes of the OE error on LG washers and what you can do about them:

1. Clogged Drain Pump Filter

The most frequent cause of the OE error is a clogged drain pump filter. Over time, lint, coins, hair, and other small objects can accumulate in the filter, obstructing water flow.

Solution:
Turn off the washer, open the filter access door (usually at the bottom front), and carefully remove the filter. Clean it thoroughly under running water and reinstall it.

2. Blocked or Kinked Drain Hose

If the drain hose bends, twists, or clogs, the washer can’t drain water properly, which triggers the OE error.

Solution:
Inspect the entire length of the hose for visible blockages or sharp bends. Straighten any kinks and clear out obstructions. Make sure the hose sits correctly and doesn’t extend too far into the standpipe.

3. Faulty Drain Pump

If the filter and hose are clear but the OE error persists, the drain pump itself may be defective. A worn-out or damaged pump can prevent water from draining efficiently.

Solution:
Listen for a humming or grinding noise during the drain cycle. If the pump isn’t working, it may need to be replaced. This is typically a job best left to professional technicians.

4. Improper Installation or Drain Height

The drain system should be installed according to LG’s specifications. An incorrect drain height or poor installation can lead to water flowing back into the washer.

Solution:
Ensure the drain hose is positioned at a height between 90–100 cm (35–39 inches) from the ground. Double-check the manual for your washer model to verify installation guidelines.

5. Control Board Malfunction

In rare cases, the issue could stem from the main control board sending incorrect signals to the drain system.

Solution:
If all other causes have been ruled out, a control board failure might be the culprit. Diagnosing and repairing this component requires a trained technician.
