Water Leaking From My Refrigerator: Finding the Source

Finding the Source of Water Leaks

Water under or inside your refrigerator needs prompt attention to prevent floor damage and potential electrical hazards.

Most Common Cause: Clogged Defrost Drain

The defrost drain removes water from the automatic defrost cycle. When clogged, water pools at the bottom of the refrigerator or leaks onto the floor.

Solution: The drain is typically located at the back of the freezer floor. It can be cleared with warm water flushed through using a turkey baster, or with a pipe cleaner.

Other Potential Causes

Damaged Water Supply Line

If your refrigerator has a water dispenser or ice maker, check the water supply line connection at the back for leaks or damage.

Cracked Drain Pan

The drain pan under the refrigerator collects defrost water for evaporation. If cracked, water leaks onto the floor. The pan is located at the bottom of the unit.

Door Seal Problems

Worn door gaskets allow warm, humid air inside, creating excess condensation that can appear as water.

Water Filter Issues

Improperly installed water filters or damaged filter housings can cause leaks.

Steps to Diagnose

1. Clean up water and place paper towels to identify leak location
2. Check water supply line connections
3. Inspect door seals for gaps
4. Look inside freezer for ice buildup (indicates drain clog)
5. Check drain pan for cracks

Preventing Future Leaks

• Periodically flush the defrost drain
• Inspect water line connections annually
• Replace worn door gaskets
• Don't overload the refrigerator (blocks vents and affects defrost)
