LG Washer Dryer: flooding

Professional Repair Guide

What is this symptom?

If your LG Washer Dryer is flooding, it may be caused by a faulty water inlet valve or improper hose connections. This issue can lead to water escaping onto your floor during the wash cycle or continuous filling. Immediate attention is necessary to prevent water damage and further complications.

Urgency: High

Important Tips for LG Models

  • LG official guidance emphasizes checking door gasket, hose connections, and internal assembly for leaks; many leak issues arise from simple hose or seal problems. (

Possible Causes

Faulty or stuck water inlet valve allowing continuous water fill

How to Identify: Water continues to flow into the washer even when the cycle is stopped; flooding persists until the supply tap is shut off manually. Water enters when it shouldn’t.

Part: Water inlet valve assembly
