You step into the kitchen and your sock gets wet. There's a puddle by the fridge. You wipe it up, and an hour later it's back.

A refrigerator leaking water on the floor is stressful, but it's rarely a disaster. In most cases the cause is something small, like a frozen drain, a loose water line, or a worn seal. The trick is finding where the water actually comes from.

This guide helps you follow the puddle back to its source, fix what you can, and know when to call for help from our refrigerator repair service.

First, Make It Safe

Water and electricity don't mix. Before you do anything else:

1. Dry the floor so nobody slips.
2. Unplug the fridge if water is close to the outlet, the cord, or the back of the machine.
3. Move food to a cooler if you need to keep the fridge off for a while. Cold food stays safe for about four hours if you keep the doors closed.
4. Turn off the water supply if you think the water line is leaking. The shutoff valve is usually under the sink or behind the fridge.

Now let's find the leak.

Follow the Puddle: Where Is the Water Coming From?

The spot where water shows up is your best clue. Match yours to the list below.

Water inside, pooling under the crisper drawers. This is almost always a clogged defrost drain.

Water at the front, under the fridge door. Think full drain pan, a bad door seal, or a fridge that isn't level.

Water at the back or along one side. Look at the water line and the inlet valve.

Water near the front grille, or around the dispenser. Suspect the water filter.

Water in the freezer, with ice around the ice maker. A frozen fill tube or a leaking ice maker is likely.

A small puddle that comes and goes. It may be plain condensation from humid air or an open door.

Keep your spot in mind. Now the details.

 Refrigerator Not Cooling But Freezer Is Fine

Common Causes of a Refrigerator Leaking Water

1. A Clogged or Frozen Defrost Drain

What happens: Every fridge melts frost off its cooling coils. That water runs down a small drain hole into a pan underneath. When the hole freezes or fills with food bits, water backs up and spills out.

Clues:

• Water pooling at the bottom of the fridge or freezer
• A sheet of ice at the back of the freezer
• Water leaking onto the floor from the front

Fix: Clear the drain. Steps are in the next section.

2. A Full or Cracked Drain Pan

What happens: The drain pan under the fridge catches the melted frost water, and it evaporates. If the pan is cracked, tilted, or the fridge makes too much water, it overflows.

Clues:

• Water appears at the front or bottom, often in humid weather
• A musty smell
• Water that follows a clogged drain

Fix: Pull out the pan (check your manual for where it sits), empty it, and clean it. If it's cracked, it needs replacing.

3. A Leaking Water Supply Line

What happens: If your fridge has an ice maker or water dispenser, a thin water line feeds it. The line can loosen, kink, crack, or wear out.

Clues:

• Water at the back of the fridge, or a constantly damp spot behind it
• A leak that continues even when the fridge is off
• A hissing sound, or a dispenser that works poorly

Fix: Shut off the water. Check the connections and look for kinks or cracks. Tighten only by hand, because overtightening can crack fittings. Replace a damaged line.

4. A Bad Water Inlet Valve

What happens: The valve lets water into the fridge. If it cracks or fails to close, it can drip or flood.

Clues:

• Water near the back or bottom of the fridge
• An ice maker that overfills
• A constant trickle sound

Fix: This needs testing and replacing. It's best left to a technician.

5. A Water Filter Problem

What happens: If the filter isn't seated properly, is overdue for replacement, or the housing is cracked, water leaks from the filter area.

Clues:

• Water dripping near the front grille or the filter
• A leak that began after changing the filter
• A filter that looks loose or off-angle

Fix: Turn off the water. Remove the filter, then reseat it until it locks. If the leak continues, try a new filter that matches your model. If the housing is cracked, it needs repair.

6. A Frozen or Leaking Ice Maker

What happens: A partly frozen fill tube sends water where it shouldn't go. An overfilled ice mold can spill. Melting ice from a power cut can also leak.

Clues:

• Ice buildup in the freezer, with water pooling below
• Ice cubes stuck together in clumps
• Slow or odd ice production

Fix: Thaw the ice maker, check the fill tube, and make sure the supply line isn't kinked. See our ice maker repair page if it keeps happening.

7. A Worn Door Gasket

What happens: If the rubber seal doesn't close tightly, warm air gets in. Moisture condenses inside and drips out.

Clues:

• Moisture around the door edges
• Frost on the walls inside
• The fridge works harder than usual

Fix: Try the dollar bill test. Close the door on a bill. If it slides out easily, the seal is weak. Clean the gasket, and if it's torn or stiff, replace it.

8. A Fridge That Isn't Level

What happens: If the fridge tilts the wrong way, water inside runs toward the door and out. A slight tilt back is normal, so the door closes. A forward tilt is not.

Clues:

• Water on the front floor
• Doors that swing open on their own
• Water that pools inside near the door

Fix: Adjust the front feet or wheels with your manual's steps, and test with a level.

9. A Failing Defrost Heater or Timer

What happens: If the defrost system doesn't work, ice builds up, and eventually melts too fast for the drain to handle.

Clues:

• Heavy frost on the back freezer wall
• Warm food, ice, and water together
• A leak that returns after you clear the drain

Fix: This needs a technician to test the heater and controls.

 Freezer Frosting Up? Here's What's Causing It

How to Clear a Clogged Defrost Drain

This is the most common fix, and it's safe to try.

1. Unplug the fridge.
2. Empty the freezer or fridge area near the drain.
3. Find the drain. It's usually a small hole at the back wall at the bottom of the freezer, or behind a panel. Check your manual.
4. Melt any ice. Pour warm (not boiling) water slowly into the hole with a turkey baster or cup.
5. Clear the debris. Use a pipe cleaner or a thin, soft tube to push out food bits.
6. Flush it with more warm water until it drains freely.
7. Check the drain pan under the fridge. Empty and clean it.
8. Plug the fridge back in, and watch for leaks over the next day.

If the freezer is heavily iced, unplug the fridge for several hours with towels around the base to let it thaw.

Is It Really a Leak? Check for Condensation

Sometimes the "leak" is just moisture.

• Humid weather makes the outside of the fridge sweat
• Leaving the door open lets warm air in
• Hot food put in the fridge adds steam
• Settings that are too cold can cause moisture
• Overfilled shelves block airflow and trap water

If the puddle is small and appears only in wet weather, check these before you call anyone.

What Not to Do

• Don't ignore it. Water can ruin flooring, swell cabinets, and grow mold.
• Don't use sharp tools to chip ice from the walls. You can puncture the coils.
• Don't pour boiling water into the drain. It can damage plastic parts.
• Don't overtighten water line fittings.
• Don't run the fridge with water near the plug.
• Don't keep mopping and waiting. A hidden leak gets worse.

Signs You Should Call a Pro

Call a technician if:

• The leak returns after you clear the drain and check the line
• Water comes from behind the fridge or from a part you can't reach
• You see heavy frost or ice in the freezer
• The fridge is also warm or not cooling
• Water is near electrical parts
• You can't find the source
• The flooring is already damaged

Repair or Replace?

Most leaks cost far less to fix than a new fridge. A drain, a gasket, a filter, or a water line are all common, affordable repairs. If your fridge is over 12 to 15 years old and needs a major repair, replacing it may make more sense. Our guide on repair or replace guide can help.

Frequently Asked Questions

Q: Why is my refrigerator leaking water on the floor?
A: Common causes are a clogged defrost drain, a full drain pan, a leaking water line, a bad inlet valve, a loose water filter, or a worn door seal.

Q: Why is there water under my crisper drawers?
A: That's usually a clogged defrost drain. Water from melting frost can't leave, so it collects at the bottom.

Q: How do I unclog a refrigerator drain?
A: Unplug the fridge, find the drain hole, and flush it slowly with warm water. Clear debris with a pipe cleaner.

Q: Why is water leaking from the front of my fridge?
A: Check the drain pan, the door seal, and whether the fridge is level.

Q: Can a water filter cause a leak?
A: Yes. A loose, old, or wrong filter, or a cracked housing, can leak.

Q: Is it safe to use a fridge that's leaking?
A: It depends. If water is near the plug or electrical parts, unplug it. Otherwise, you can often use it briefly, but fix the leak soon.

Q: How much does it cost to fix a leaking refrigerator?
A: It depends on the cause. A cleared drain costs little. A valve or heater costs more. Get a quote first. 

Q: Why does my fridge leak more in summer?
A: Humid air brings more moisture into the fridge, which makes more condensation and more water for the drain pan.
