Refrigerator Leaking Water? Common Causes and Solutions

Clogged or Frozen Defrost Drain

The defrost drain removes water created during the automatic defrost cycle.

Water drips down into the defrost drain tray under the evaporator and then the defrost drain tube carries the water down to the defrost drain pan at the bottom of the refrigerator in the machine compartment. In between automatic defrost cycles, the water in the defrost drain pan evaporates away.

If the defrost drain tube gets clogged or frozen, water overflows the evaporator defrost drain tray and drips inside the fridge or the freezer compartment.

In a top-freezer refrigerator, the leaking water typically winds up at the bottom of the refrigerator compartment under the crisper drawers.

Solution:

Follow this procedure to clear a clogged or frozen defrost drain:

• Unplug the refrigerator and remove the evaporator cover panel in the freezer to access the evaporator defrost drain tray. In some top-freezer refrigerators, you’ll need to remove the ice maker before removing the evaporator cover.
• Melt ice in the evaporator defrost drain tray under the evaporator using warm water and a small funnel or turkey baster. Water may seep from under the refrigerator if water drains down and overflows the drain pan at the bottom of the fridge.
• If the water doesn’t drain through the defrost drain tube after melting the ice in the defrost drain tray under the evaporator, use a pipe cleaner or straw to unclog the top of the drain tube. Check to see if the drain is clear by pouring some warm water down the tube by again using a small funnel or turkey baster.
• After clearing the defrost drain, reinstall the evaporator cover panel and plug in the refrigerator power cord to restore electrical power.

If the evaporator drain tray and defrost drain tube keeps freezing up and overflowing, schedule refrigerator repair service to have a technician diagnose and repair the problem. The tech may need to install a defrost drain tube heater to prevent water from freezing in that area.

Overflowing or Leaking Defrost Drain Pan

The drain pan at the bottom of the refrigerator in the machine compartment collects water from the evaporator drain pan under evaporator. The defrost drain tube carries the water from the evaporator defrost drain pan to the defrost drain pan.

In between defrost cycles, water in the defrost drain pan should evaporate according to refrigerator design.

If the drain pan cracks, it will leak water onto the floor that will seep out under the refrigerator.

Excessive frost caused by air leaking into the fridge through a bad door seal or other reasons can cause the defrost drain pan to overflow.

Solution:

Unplug the refrigerator and remove the machine compartment cover. Examine the defrost drain pan and replace it if it’s cracked or damaged.

If the defrost drain pan is full and overflowing, empty the water out of the pan. Replace the refrigerator door seals or fix the cause of warm, moist air leaking into the refrigerator and causing excessive frost.

Here’s a DIY video that shows how to replace the refrigerator door seal on a common type of fridge:

Have a service technician replace the door seal or address the leaking problem if you’re unable to address the issue on your own.

High humidity or frequent door openings can also cause excessive frost leading to an overflowing defrost drain pan. Minimize refrigerator door openings and consider moving the refrigerator indoors if you’re using in a garage or a space that isn’t climate-controlled.

Water Dispenser Leak

Water dripping from the water dispenser in the door of the fridge is often caused by air trapped in the water dispenser supply line.

The water dispenser will also drip water if the inlet water valve doesn’t shut properly.

A loose or damaged water line can cause also cause a leak.

Solution:

To prevent water from dripping from the water dispenser in the door, purge a gallon of water as constantly as possible through the water dispenser immediately after installing a new water filter.

Replace the inlet water valve if it isn’t closing properly and causing water to leak from the dispenser and ice maker.

Inspect the dispenser water supply line for kinks, cracks, or loose connections. Tighten any loose water line connections and replace any sections of water line or fittings that leak.

Have a service technician find and fix the leak if you’re unable to resolve the problem on your own.

Ice Dispenser Leaking

An ice cube or ice chips stuck in the ice door or in the ice dispenser chute can prevent the ice door from fully closing. Ice cubes or chips in that area will melt and drip out of the ice dispenser chute.

A loose or damaged ice door can cause also cause water to drip from the ice dispenser.

Solution:

Open the door and check the ice dispenser chute for cubes or ice chips. Clear out the ice chute if find stuck cubes or ice chips.

If the ice door is damaged or broken, replace it.

Schedule refrigerator repair service to have a technician replace that part if you’re not completely confident that you safely replace it on your own.

Ice Maker Leaking

Water can overflow the ice mold in the ice maker if the inlet water valve doesn’t shut off properly. A cracked ice mold or a defective ice maker module can also cause water to leak from the ice maker.

Solution:

Unplug the refrigerator and check the ice maker mold for a crack or damage. Replace the ice maker module if its ice mold is cracked or damaged.

If water constantly trickles into the ice maker, you’ll likely need to replace the inlet water valve. Here’s a video that show how to complete that repair on a common type of refrigerator:

If these tips don’t help, have a service technician examine the ice maker and replace it if necessary.

Preventing Future Leaks

Regularly check the refrigerator and freezer door gaskets. Replace the door gaskets when you notice that they’re worn or damaged.

Be sure that you purge a gallon of water through the water dispenser immediately after replacing the water filter to avoid air in the water dispenser supply line from causing drips.

Schedule professional refrigerator maintenance and cleaning service yearly to keep your fridge in top shape and help prevent leaks. Annual maintenance checks will also help keep your refrigerator lasting longer.

Water leaking from your fridge doesn’t have to turn into a major problem.

With a little troubleshooting and maintenance, you can keep your refrigerator running efficiently and avoid future issues.

Frequently Asked Questions

How do I stop my fridge from leaking water inside?

A clogged defrost drain is the #1 cause of leaking inside a fridge. Unplug the refrigerator and clear any blockages in the drain with warm water or a pipe cleaner. A damaged door seal will cause excessive frost that can result is leaking water when the extra frost melt off the evaporator coils during defrost. Ensure the door gaskets are sealing properly; replace if damaged. Regular maintenance and proper use can prevent water buildup inside your fridge.

How do you fix an internal leak in a refrigerator?

Unplug the refrigerator and unclog the defrost drain. Flush the drain with warm water and a mixture of baking soda or vinegar to clear blockages. Inspect water line connections and tighten any loose connections if the fridge has a water dispenser or ice maker. Ensure door gaskets are sealing properly to prevent excess condensation and water overflowing the defrost drain.

Why is there standing water in the bottom of my refrigerator under crisper drawers?

Water collecting under the crisper drawers in a top-freezer refrigerator is often caused by a clogged defrost drain tube below the evaporator. Unplug the fridge and remove the back panel inside the freezer compartment to access the defrost drain tray below the evaporator. Clear the clog using warm water and a pipe cleaner or straw if necessary.

Why is water dripping down the back of my fridge inside?

Water dripping down the back panel inside the fridge is often caused by a clogged defrost drain tube. The defrost heater melts frost off the evaporator coils and that water is supposed to drain out of the collection tray below the evaporator through a drain tube and into a drain pan next to the compressor. When the drain tube gets clogged with ice, the water will overflow and drip down the back of the refrigerator compartment. Unplug the fridge and remove the evaporator cover. Clear the ice clogging the drain tube below the evaporator drain tray to prevent the water leak.
