Refrigerator Leaking Water on the Floor? Find the Source and Fix It
Where the water appears is the best clue. A puddle under the crisper drawers points to the drain; water at the back points to the supply line.
A refrigerator leaking water on the floor is most often caused by a clogged defrost drain, a cracked or misplaced drain pan, a leaking water supply line or inlet valve for the ice maker and dispenser, or a fridge that is not level. Start by noting where the water appears. If the leak is fast or near electrical outlets, shut off the water supply to the fridge, unplug it if you can do so safely, and dry the area before you investigate.
First steps
- If water is spreading, close the shut-off valve on the fridge’s water line (often under the sink, in the basement or behind the fridge). If you cannot find it, close the main water shut-off; see how to shut off water to your house.
- Do not stand in water while touching the plug. If an outlet is wet, switch off the breaker first.
- Mop up and dry the floor so you can see where new water appears.
- Note the location: front underneath, inside the fridge, back near the wall, or under the freezer.
Find the source by location
| Where the water is | Likely cause | Fix |
|---|---|---|
| Under the crisper drawers, then on the floor at the front | Clogged defrost drain | Clear and flush the drain |
| Under the fridge, front or middle | Cracked, shifted or overflowing drain pan | Reseat or replace the pan |
| Back of the fridge, near the wall | Water supply line or inlet valve | Tighten or replace line or valve |
| Below the dispenser | Drip tray overflow, dispenser leak | Empty tray, check dispenser |
| Inside the freezer, ice on the floor | Defrost drain frozen, ice maker overfill | Thaw drain, check ice maker |
| Around the doors, sweating | Door seal or humid air | Check gaskets, close doors fully |
What you need
- Towels and a shallow tray
- A turkey baster or a squeeze bottle
- Warm water and a little baking soda
- A thin, flexible tool such as a pipe cleaner (nothing sharp)
- A level, flashlight and adjustable wrench
Clogged defrost drain
Frost-free fridges melt frost off the cooling coil and send the water through a drain to a pan underneath, where it evaporates. If food particles or ice block the drain, water backs up and pools under the crisper drawers, then spills out the front.
- Unplug the fridge.
- Find the drain opening. On many models it is a hole or trough at the back of the fresh-food compartment, under the crisper drawers, or behind the rear freezer panel. Check your manual.
- If it is frozen, let it thaw (a manual defrost may be needed).
- Use a baster to push a little warm water into the drain until it flows freely. Clear visible debris with a pipe cleaner.
- Empty and clean the drain pan afterward, since it will have filled.
If the drain is behind a freezer panel with wiring or the heater attached, consider a technician. Repeated freezing can point to a failed defrost heater or drain heater.
Drain pan problems
With the fridge unplugged, remove the front grille and look for the pan, or pull the fridge out if the pan is at the back. A cracked pan leaks; a pan knocked out of position after moving or cleaning can let water miss it. Reseat it as designed or order the exact replacement for your model.
Water supply line and inlet valve
If your fridge has an ice maker or water dispenser, a thin supply line runs to an inlet valve at the back. Leaks often occur at the compression fitting at the shut-off valve, at the connection to the fridge, or from a cracked plastic line.
- Shut off the water to the fridge and unplug it.
- Pull the fridge out carefully without kinking the line.
- Look and feel along the line for drips, especially at fittings.
- Snug a leaking compression nut gently; overtightening can crack fittings.
- Replace a brittle or cracked line. A cracked inlet valve also needs replacement.
See our guides on disconnecting a refrigerator water line and replacing a fridge water line valve. If supply plumbing in the wall leaks, call a licensed plumber.
Water filter and dispenser
A filter that is not fully locked in, or the wrong filter, can drip inside the fridge. Reseat it according to the manual and check for cracks. Empty the dispenser drip tray, which some models do not drain automatically.
Leveling
Many fridges are designed to tilt slightly back so the doors close and water flows toward the drain. A fridge that tilts forward can spill condensation. Adjust the front legs or rollers following your manual.
Ice maker problems
An ice maker that overfills, or ice spills that melt, can lead to water in the freezer and on the floor. If ice production is also off, see ice maker not working.
When to call a pro
- The leak continues after the drain, pan and line are checked
- The defrost drain keeps freezing
- Water is near wiring, or the outlet got wet
- Leaks inside walls or floors (licensed plumber)
- The fridge is under warranty (DIY repairs may void it)
Water on wood or laminate floors can cause damage quickly, so dry the area and check underneath if leaks persist.
Bottom line
Use the location of the water to find the cause. Clear the defrost drain, reseat or replace the drain pan, check the supply line and filter, and level the fridge. Shut off water and power first, and call a technician or plumber if the leak persists.
FAQ
Why is my fridge leaking water under the crisper drawers?
Usually a clogged or frozen defrost drain. Unplug the fridge and flush the drain with warm water.
Can I use my fridge while it is leaking?
For a slow drain leak, you can use it while you plan a fix, but dry the floor and keep water away from outlets. For a supply line leak, shut off the water.
Why does my fridge leak after I change the filter?
The filter may not be fully seated or may be the wrong type. Reseat it as the manual describes.
Is a leaking refrigerator dangerous?
Water near electrical outlets is a risk. Switch off the breaker if an outlet is wet.
