How to Fix a Fridge Leaking Water: Causes and Solutions

How to Fix a Fridge Leaking Water

Finding water on the floor around your fridge is frustrating — and it's one of the most common fridge problems. The good news: most water leaks from a fridge are caused by one of a small number of easily identifiable issues, and many can be fixed without calling a technician. This guide walks you through the most common causes and how to fix them.

Common Causes of a Fridge Leaking Water

1. Blocked Defrost Drain

This is the most common cause of water leaking inside the fridge or pooling under it. The defrost drain is a small drain hole at the back of the fridge compartment (or at the bottom) that removes water from the automatic defrost cycle. If this drain becomes blocked with food debris or ice, water backs up and leaks out.

How to fix it:

1. Remove everything from the bottom shelf
2. Find the drain hole at the back of the fridge (it may be under a panel)
3. Use a turkey baster or syringe filled with hot water to flush the drain
4. Alternatively, use a small piece of wire to clear the blockage
5. Once clear, water should drain freely

2. Water Inlet Valve (Fridge with Ice Maker or Water Dispenser)

If your fridge has a water dispenser or ice maker, a cracked or faulty water inlet valve can cause water to drip or pool behind or under the fridge. Check the valve (usually at the back bottom of the fridge) for visible cracks or damage. A faulty inlet valve typically needs professional replacement.

3. Cracked or Damaged Water Supply Line

Fridges with water dispensers have a water supply line running from the wall to the back of the fridge. If this line is kinked, cracked or has loose connections, it can leak. Check the line and connections, and replace it if damaged — replacement supply lines are inexpensive and available at hardware stores.

4. Condensation on the Outside of the Fridge

If water appears on the outside of your fridge rather than underneath it, the issue is likely condensation. This can happen when:

• The door seal (gasket) is worn or damaged and warm air is getting in
• The fridge is in a humid location
• The door isn't closing properly

Check the door seal by closing the door on a piece of paper — if the paper slides out easily, the seal has lost its grip and needs replacing.

5. Drain Pan Overflowing

Most fridges have a drain pan underneath that collects water from the defrost cycle, which then evaporates. If the pan cracks, overflows (from an unusually high defrost cycle) or is located incorrectly, water can leak out from under the fridge. Pull out the fridge and check the drain pan.

6. Ice Maker Overfilling

If your fridge has an ice maker and it's producing too much ice or malfunctioning, it can overflow and cause water to leak inside the freezer and drip down into the fridge. Check that the ice maker is functioning correctly and not overfilling.

When to Call a Technician

Call a technician if:

• You can't identify the source of the leak after checking the above
• The water inlet valve or ice maker needs replacement
• The fridge is leaking refrigerant (a different kind of leak — accompanied by poor cooling and sometimes a chemical smell)
• The fridge is old and experiencing multiple issues

Time for a New Fridge?

If your fridge is more than 10–12 years old and experiencing repeated problems including leaks, it may be more cost-effective to replace it than to repair it. Oceania Appliances stocks a wide range of new fridges at competitive prices with delivery across all of greater Sydney.
