LG Washing Machine: not draining

Professional Repair Guide

What is this symptom?

Is your LG washing machine not draining properly? After completing the wash cycle, water remains in the drum, often accompanied by an OE or drain error. This common issue can stem from a clogged drain pump filter, a kinked drain hose, or even a faulty drain pump. Understanding the causes can help you troubleshoot effectively.

Important Tips for LG Models

  • LG specifically notes that OE error and not draining can be caused by frozen drain pump in cold conditions and recommends warm water to thaw and drain system.

Faulty drain pump
