If your refrigerator is leaking water and you have checked the most common causes of a leaking refrigerator, such as a clogged defrost drain, leaking water tank assembly, or a damaged water inlet valve, you may not know what to do next. Here are three less common reasons why your refrigerator may be leaking water.

#1 Water Filter Housing & Head

The first thing you should check out is the water filter housing. This is generally attached or near the water tank, and it can develop cracks. All the water that goes into your water dispenser and ice filter can potentially leak out of the housing for the filter. You may just not have put the housing back on properly when you changed the filter, and just need to put it back on properly. Or the housing may be cracked or damaged and need to be replaced entirely.

Also, make sure that you check the water filter head where it connects to your refrigerator. If the head or seal around it has become cracked or damaged, water can easily leak out of the water housing area.

#3 Water Filter

You also need to check your actual water filter. If the water filter has become clogged and needs to be replaced, it could be causing issues with your water system overall that could lead to leaking water.

Or, if you recently changed out the water filter on your refrigerator, you may not have put it back on correctly. If everything is not attached properly, water may easily leak out of the water filter attachment area. To make sure that everything is installed properly, you'll want to remove the filter and put it back on to ensure that it is tightly in place.

#3 Drain Pan

Refrigerators that are designed to defrost on their own have drain pans located underneath the refrigerators. Water that comes off of the evaporator coils makes its way into the drain pan. Then the condenser fan assists the water with evaporating by blowing warm air across the top of the pan. When this process works correctly, you never have to even drain the drain pan manually. However, if the drain pan gets cracked or damaged or the condenser fan fails to operate correctly, water will leak out onto your floor from the damaged pan or overflow due to a lack of evaporation.

If none of these fixes worked, a refrigerator repair technician like those from A OK Appliance Service may be able to figure out what is really going on.
