Lg Refrigerator: ice maker leaking

Professional Repair Guide

What is this symptom?

Experiencing water dripping or pooling around your LG refrigerator's ice maker? This common issue can occur during or after ice production, often due to incorrect water pressure, a faulty water inlet valve, or clogged drain lines. Addressing these problems promptly can prevent further damage and maintain your appliance's efficiency.

Important Tips for Lg Models

  • Official LG guidance confirms that both high and low water pressure at the supply valve can cause the ice maker to leak, and recommends purging air and adjusting water pressure.turn0(LG AU
  • LG support notes that water droplets near ice maker can occur if freezer or ice maker door is left open allowing warm air causing condensation/melt.(LG AU
