The short answer
Check the Defrost Drain
The most common cause is a clogged defrost drain. Frost melts during the defrost cycle, and the water should flow through a small drain tube into the drip pan at the bottom. If the drain is blocked with food particles or ice, water backs up and spills onto the floor.
To check, locate the drain hole inside the fridge, usually at the back wall. Flush it with warm water using a turkey baster or a small funnel. If the water flows freely, the clog is cleared. If not, you may need to gently clear the tube with a flexible brush or a straightened wire hanger.
- Pull the fridge out carefully to access the back panel
- Look for a small drain hole inside the fridge
- Use warm water, not boiling, to melt any ice
- Clean the drip pan and check for cracks
- If the drain is frozen, unplug the fridge and let it thaw
- Recheck the floor after a few hours for new leaks
Inspect the Water Supply Line
If your fridge has an ice maker or water dispenser, a split or loose water supply tube can leak. The tube is usually a thin plastic or copper line running from the wall to the fridge. Over time, it can crack or become disconnected, especially if the fridge was moved recently.
Turn off the water supply valve behind the fridge and inspect the tube for cracks or kinks. Tighten any loose connections with a wrench. If you find damage, replace the tube. If you cannot locate the shutoff valve, check your home's main water shutoff and keep that location written down for future emergencies.
Look at the Ice Maker
A malfunctioning ice maker can also cause water to leak. The water inlet valve may stick open, sending too much water into the ice mold, which overflows and drips down. Or the ice maker's fill tube can crack, allowing water to escape during the fill cycle.
Inspect the ice maker for visible cracks or ice buildup around the fill tube. If the ice maker is the culprit, you may need to replace the water inlet valve or the ice maker itself. A local appliance repair person can handle that. Meanwhile, turn off the water supply to the ice maker to stop the leak. If your fridge has no ice maker or water dispenser, skip this step and focus on the drain and door seal.
Examine the Door Gasket
A worn or dirty door gasket lets warm air enter the fridge, causing excessive frost and ice buildup. That ice can melt and leak onto the floor. Check the gasket for cracks, tears, or gaps. Close the door on a piece of paper; if you can pull it out easily, the seal is weak.
Clean the gasket with warm soapy water to remove debris. If it is damaged, replace it. A new gasket is often affordable and easy to install. This fix can also improve your fridge's efficiency, reducing energy use.
When to Call a Pro
If you have cleared the drain, checked the water line, and inspected the ice maker and gasket, and the leak persists, it may be a sign of a deeper issue. A plumber can test your water pressure and inspect the supply line. A local water damage pro can assess any floor damage that has already occurred.
Water on the floor can soak into nearby cabinets, baseboards, and subflooring, leading to warping or mold. If you notice soft spots or a musty smell, act quickly. The pros can dry the area and remove damaged flooring if needed. Water damage cleanup often involves removing wet materials and drying the space to prevent mold growth.

Why is my fridge leaking water from the bottom?
Water pooling under the fridge usually comes from a clogged defrost drain or a cracked drip pan. The drip pan catches water from the defrost cycle, but if it cracks or overflows, water ends up on the floor. Check and clean both parts first.
Can I fix a fridge water leak myself?
Yes, for simple clogs or loose lines. Clear the defrost drain, tighten connections, and clean the gasket. If the water line is cracked or the ice maker is faulty, you may need a plumber or appliance repair person. Always turn off the water supply before attempting repairs.
How do I find the water shutoff valve for my fridge?
The shutoff valve is usually under the sink, behind the fridge, or in a utility closet. Look for a small brass or chrome valve on the water supply tube. If you cannot find it, check your main shutoff. Write down the location for future reference.
