Water on the floor in front of the refrigerator is one of those problems that can be minor or can quietly damage a subfloor, cabinets or a finished floor. The first job is to figure out where the water is coming from, because a refrigerator has several possible sources, and each has a different fix.
Right now: limit the damage
- •Wipe up the water and put towels down.
- •If the leak is heavy or steady, turn off the water supply to the refrigerator. The shutoff is usually under the kitchen sink or behind the fridge. That stops any leak on the water side.
- •Unplug the refrigerator before pulling it out, and don't stand in water while unplugging it. If the outlet is wet, turn off the breaker first.
- •Move the refrigerator carefully. Pull it straight out so you don't tear the water line or scratch the floor.
Where the water comes from
Inside the refrigerator: the defrost drain
Frost-free refrigerators periodically melt the frost off the freezer coil, typically one or more times a day. The meltwater runs down a drain to a pan under the refrigerator, where it evaporates. If that drain clogs, usually with ice or food debris, the water has nowhere to go.
Signs: water pooling under the crisper drawers, ice on the freezer floor, or water dripping from the front of the refrigerator onto the floor.
What you can do:
- Look for the drain opening. In the freezer, it's typically at the bottom of the back wall, sometimes behind a panel. In the fresh-food section, it's often a small hole or trough at the back, under the crispers.
- Clear it gently. Pour a little warm water into the drain with a turkey baster or small cup. If it backs up, a pipe cleaner or a length of flexible plastic tubing can help clear the blockage. Don't use sharp objects near the freezer coil.
- Clean up the ice. If there's ice in the freezer drain trough, it may need a full defrost. Unplug the fridge, move the food to coolers, and leave the doors open until all the ice has melted.
If the drain keeps refreezing after you clear it, part of the defrost system, or a drain heater on models that have one, may not be working. That needs diagnosis.
Behind or under: the water line and valve
On refrigerators with an ice maker or dispenser, water comes in through a supply line to a valve at the bottom back of the unit.
Signs: water on the floor behind or under the refrigerator, especially when the ice maker fills or the dispenser is used.
What to check: with the refrigerator pulled out, dry the area and watch the supply line connection at the wall, along the line, and where it connects to the refrigerator. Plastic lines can crack with age, and compression fittings can loosen.
- •A leak at a fitting can often be fixed by tightening it gently or replacing the ferrule and nut. Don't overtighten plastic fittings.
- •A cracked or brittle line should be replaced. A braided line is more durable.
- •A leak from the valve itself on the refrigerator needs a technician, because the valve is connected to mains voltage wiring.
The water filter
Signs: water dripping from the filter housing, inside the refrigerator or in the base grille, depending on where the filter sits.
What to check: a filter that isn't fully locked, the wrong filter, or a cracked housing all leak. Remove the filter, check the seals, and reinstall it firmly. If it still leaks with a correct, new filter, the housing may be cracked.
The dispenser
Signs: drips below the door dispenser.
What to check: some dripping just after use is normal. Constant dripping can point to a water valve that doesn't close fully, often caused by scale in hard water. Our guide to hard water in ice makers and fridge valves covers this.
The drain pan
Signs: water under the refrigerator with no other obvious source.
What to check: the drain pan under the fridge is behind the bottom grille. It can crack or be knocked out of place. On some models it's easy to reach, and on others it needs the refrigerator moved and a rear panel removed.
Condensation
Signs: water on the outside of the cabinet, around the doors, or under the fridge on humid days.
On humid summer days, some condensation on the outside of the cabinet near the doors can happen. Heavy condensation usually means warm, moist air is getting in: a door that isn't sealing, or a door left open. Check the gaskets and that the refrigerator is level.
Check that it's level
Most manufacturers recommend setting a refrigerator with the front slightly higher than the back, so the doors swing closed and the defrost water drains toward the back. If the fridge tilts forward, water can run out of the front. San Antonio's clay soils can shift floors over the years. Use a level on top of the refrigerator and adjust the front feet or rollers as the manual describes.
When to call a technician
Call for service if:
- •The defrost drain keeps freezing and clogging after you clear it.
- •Water comes from inside the cabinet and you can't find the source.
- •The water valve at the back of the refrigerator is leaking.
- •The filter housing leaks with a correct, new filter installed.
- •There's water near electrical parts at the back of the refrigerator.
Our refrigerator repair page covers all the major brands. A drain that keeps freezing can go hand in hand with a defrost fault that also affects cooling. That pattern is covered in refrigerator not cooling in summer. If the ice maker has also stopped filling, see our ice maker troubleshooting guide.
Frequently asked questions
Is it safe to use a leaking refrigerator?
For a small leak from the defrost drain, usually yes, while you arrange a fix. For a leak from the water line or valve, turn off the water supply. Any water near electrical parts is a reason to unplug the fridge until it's inspected.
Why is there ice on the freezer floor?
That's often the defrost drain clogged with ice, so the meltwater refreezes instead of draining.
Can a leaking refrigerator damage my floor?
Yes. Slow leaks can damage subfloors and cabinets without being visible. Check under the refrigerator periodically if you've had a leak before.
