Finding a puddle at the bottom of your fridge or water pooling under the crisper drawers? An interior leak is messy, but it usually traces back to one of two things: a blocked defrost drain or a water line problem. Both are fixable at home.
Here is what causes water inside a refrigerator and how to stop it.
This article will teach you:

Why Water Pools Inside the Fridge
Notice where the water collects, since the location is a strong clue. The usual causes are:
- A clogged defrost drain, which backs up melt water so it drips into the fridge instead of draining away.
- A leaking water inlet valve or water line feeding the dispenser and ice maker.
- A frozen or cracked ice maker fill tube dripping water.
- A worn door gasket letting warm air in, which creates condensation.
What You’ll Need
- Warm water and a turkey baster
- A pipe cleaner or flexible brush
- A towel
How to Fix a Fridge Leaking Inside
Start with the most common cause.
- Clear the defrost drain. Find the drain hole at the back of the freezer floor and flush it with warm water to melt any ice clog.
- Check the water lines. Inspect the inlet valve and lines behind the fridge for drips or loose fittings.
- Inspect the fill tube. A cracked or frozen ice maker fill tube can drip inside; thaw or replace it.
- Test the door seal. A weak gasket lets in humid air that condenses, so check it for gaps.
Pro Tip: A clogged defrost drain is the number one cause of interior fridge leaks. Flushing it with warm water clears most clogs in a few minutes.
When to Look a Little Deeper
Because a leak can start at the drain, a line, or the fill tube, it helps to trace the water to its source, and reviewing how to thaw a frozen ice maker fill tube or handle the refrigerator water inlet valve helps. Condensation leaks often tie back to a worn door gasket.
If the leak comes from the drain system or a supply part, you can install a new fridge drain tube, or replace a clogged defrost drain tube.
When to Call a Pro
If the drain is clear and the lines are dry but water keeps appearing, a sealed-system or defrost fault may be behind it. A technician can diagnose those safely.
Wrapping Up
Most interior fridge leaks come down to a blocked drain or a line. Here’s the recap:
- Flush the defrost drain with warm water.
- Check the inlet valve and water lines for drips.
- Inspect the ice maker fill tube.
- Confirm the door gasket seals tightly.
Clear the drain first and the puddles usually stop. You’ve got this.
