Whirlpool Refrigerator Leaking Water: Finding the Source

Water on the floor in front of a refrigerator is one of the few appliance problems that can damage more than the appliance. In a San Francisco flat with hardwood floors, or an upper-floor unit with neighbors below, even a slow drip matters. The good news is that refrigerator leaks fall into a short list, and the location of the water narrows it quickly.

Read the puddle first

Before you move anything, notice where the water is and how it behaves. A few minutes of observation can save a technician a lot of searching.

• Inside the fresh-food compartment, under the crisper drawers. This often means the defrost drain is frozen or clogged, so meltwater pools instead of leaving.
• Under the freezer floor or in the bottom drawer. Meltwater that refroze, or a drain that backed up, can show up here as ice.
• Across the front of the unit on the floor. This can be the drain pan overflowing, a door that does not seal, or a supply line connection.
• Toward the back, near the wall. Suspect the water supply fitting, the valve, or the line running to the ice maker and dispenser.
• Only after dispensing water or ice. The dispenser tubing, the filter housing or the tray under the dispenser is likelier than the cooling system.

The usual sources

Defrost drain. During defrost, a heater melts frost off the evaporator coil and the water runs through a small drain to a pan near the compressor, where warm air evaporates it. If that drain freezes or collects food debris, water backs up and spills into the compartment, then out the door. A drain pan that is cracked or has shifted can spill too.

Water supply line. Refrigerators with an ice maker or water dispenser are fed through a small tube from a valve on the wall. A loose compression fitting, a pinched or kinked line behind a tightly pushed-in cabinet, or an aged tube can drip slowly. These leaks are worst in galley kitchens where the refrigerator sits flush to the wall and the line gets crushed.

Water filter. A filter that was twisted in off-line, or a housing that has cracked, can drip at the filter location. A filter due for replacement does not leak by itself, but an old one can clog and push pressure elsewhere. If your display shows the filter indicator, the H2O light page explains what that light means.

Inlet valve. The solenoid valve at the back lets water into the ice maker and dispenser. If it fails to shut fully, the line stays under pressure and can weep at a joint.

Door gasket and tilt. Warm humid air that gets past a worn gasket condenses inside. A refrigerator that leans slightly forward drains better; one that leans back can let water collect inside the door side. Sweat on the outside and drips from a gasket are not the same as a defrost problem.

Ice maker fill. If the fill tube misses the mold, or the mold is cracked, water can run into the freezer and refreeze into a sheet of ice.

Owner checks that are safe

1. Dry the floor and place a towel or shallow tray, so you can see whether more water appears and from where.
2. Look at the doors. Make sure they close, that the gaskets are clean and not folded, and that nothing keeps the freezer drawer from shutting.
3. Pull the unit out only as far as the supply line allows. Look at the line for a kink or a wet fitting, and straighten it gently if it is bent. Do not stretch it.
4. If a leak is clearly at the supply, close the water supply valve to the refrigerator. Many buildings have a small shutoff behind or under the sink.
5. Remove ice or items that block drawers, and look at the lowest area inside for standing water or a cube of ice over the drain.
6. Check whether the water filter is seated and turned fully into place, according to the instruction sheet that came with it.

If you see ice that blocks the drain at the back wall, resist the urge to melt it with a hair dryer pointed at the panel or to scrape it. Heat near plastic and wiring, and tools near the coil, create new problems.

Things to avoid

• Do not remove the rear or lower panels to find the pan; that area has electrical connections near moving water.
• Do not leave the water line running after you find a leak on the supply side.
• Do not seal the door seam with tape or caulk. It hides the real cause and can tear the gasket later.
• If water has reached an outlet, a power strip or the base of the cabinet, switch off the breaker before touching anything near it.

When it needs a technician

Book a visit when the leak returns after the doors and filter check out, when ice keeps forming at the bottom of the freezer, when the supply line is wet at a fitting you cannot reach safely, or when you see water around the electrical area. Technicians check the drain path with the cabinet access they have, test the inlet valve and the defrost heater, and look for cracks in the pan or the ice maker mold.

Give us the model number if you can; it is usually on the inside wall or around the door frame. Tell us where the water appears, whether it follows the ice maker or dispenser, and whether you shut off the water. We diagnose first, give you a written estimate and repair nothing without your approval. See Whirlpool refrigerator repair for what a visit covers, the Whirlpool refrigerators overview for the lineup, and the ice maker guide if the leak and the missing ice show up together.
