Lg Washing Machine: door sensor malfunction and water leakage

Professional Repair Guide

What is this symptom?

Experiencing a door sensor malfunction and water leakage in your LG washing machine? This issue often manifests as door error codes (dE, dE1, dE2) and can lead to water escaping from the door gasket area, especially during cycles. Identifying the cause can help prevent further damage and save on repair costs.

Urgency: Medium

Important Tips for Lg Models

  • LG DE/dE1/dE2 error codes specifically indicate door locking issues and are documented in official support guides.
  • Reset procedures for DE errors are recommended by LG support to clear temporary sensor lock issues.

Possible Causes

Faulty door lock mechanism

How to Identify: Washer displays dE error, door does not latch/lock securely, cycle won’t start or stops mid‑cycle.

Part: Door lock assembly (interlock/sensor)

Obstruction or misalignment preventing proper door closure

How to Identify: Items caught in gasket, visible misalignment or seal damage, DE1/DE2 errors persist despite resets.

Part: Door latch/hinge/door seal

Water leak from front door area due to improper sealing or gasket failure

How to Identify: Water pooled around front door after or during cycle; no leaks from hoses or supply outside gasket area.

Part: Front door gasket/seal

Control board or electrical connection issue

How to Identify: Door and latch appear intact; error persists after resets/visual inspection; intermittent or unexplained DE errors.
