Lg Refrigerator: leak

Professional Repair Guide

What is this symptom?

Experiencing a leak from your LG refrigerator? This could manifest as water pooling inside, at the bottom front, or on the floor. Common culprits include clogged defrost drains or faulty water supply connections that prevent proper drainage and evaporation.

Urgency: Medium

Important Tips for Lg Models

  • Official LG support points to water line connection issues at the back causing leaks, along with drain problems.
  • LG official Japanese support lists similar causes and recommends checking drain, drain pan, and gasket issues.

Possible Causes

Clogged or misaligned defrost drain and drain hose

How to Identify: Water pooling inside the fridge interior or around the vegetable drawer and not draining into the drip pan indicates a clogged or blocked drain; visible debris or ice buildup at the drain opening.

Part: Defrost drain, drain hose

Improper or damaged water supply line connection

How to Identify: Water pooling under or behind the fridge, especially near the back, with moisture around the water line fitting suggests the line is loose or damaged.

Part: Water supply line
