Refrigerator Leaking Water: Common Causes and How to Fix It

If your refrigerator is leaking water, the problem could be caused by a clogged defrost drain, damaged water supply line, faulty water inlet valve, or another component in the water system. Before replacing any parts, inspect the most common causes listed below.

Possible Causes

1. Clogged defrost drain
2. Damaged or loose water supply line
3. Faulty water inlet valve
4. Cracked drain pan
5. Frozen defrost drain
6. Clogged or improperly installed water filter
7. Ice maker leaking water
8. Refrigerator not level

1. Clogged Defrost Drain

Most Common Solution

The defrost drain carries melted frost from the evaporator to the drain pan beneath the refrigerator. If the drain becomes clogged, water can back up and leak onto the floor or inside the refrigerator.

What to do:

• Unplug the refrigerator.
• Locate the defrost drain inside the freezer.
• Remove any ice or debris blocking the drain.
• Flush the drain with warm water until it flows freely.

2. Damaged or Loose Water Supply Line

A cracked, loose, or damaged water supply line can leak water behind or underneath the refrigerator.

What to do:

• Inspect the water supply line from the household water valve to the refrigerator.
• Check all fittings for leaks.
• Tighten loose connections.
• Replace the water line if it is cracked or damaged.

3. Water Inlet Valve

The water inlet valve controls the flow of water to the ice maker and water dispenser. A cracked valve or leaking connection can allow water to escape.

What to do:

• Inspect the valve for cracks or signs of leaking.
• Check the inlet and outlet fittings for loose connections.
• Replace the valve if it is damaged or leaking.

4. Drain Pan

The drain pan collects water during the defrost cycle. If it becomes cracked or damaged, water may leak onto the floor.

What to do:

• Locate the drain pan beneath the refrigerator.
• Inspect it for cracks or damage.
• Replace the drain pan if necessary.

5. Frozen Defrost Drain

A frozen defrost drain can prevent water from draining properly, causing it to overflow inside the freezer or refrigerator.

What to do:

• Remove any ice covering the drain opening.
• Flush the drain with warm water.
• Verify water flows freely into the drain pan.

6. Water Filter

A damaged, clogged, or improperly installed water filter can leak around the filter housing.

What to do:

• Remove and reinstall the water filter.
• Inspect the filter for damage.
• Replace the filter if it is cracked or worn.
• Verify the filter is fully locked into place.

7. Ice Maker

A leaking ice maker or cracked ice maker fill tube can allow water to drip inside the freezer or onto the floor.

What to do:

• Inspect the ice maker for visible leaks.
• Check the fill tube for cracks or ice blockages.
• Replace damaged components as needed.

8. Refrigerator Not Level

If the refrigerator is not level, water may not flow correctly into the drain pan and could leak onto the floor.

What to do:

• Check that the refrigerator sits level from front to back and side to side.
• Adjust the leveling legs as needed.
• Verify the doors close properly after leveling.
