Water leakage is a common but alarming refrigerator problem. This issue is often caused by a blocked defrost drain, or a clogged or frozen water supply line.
Your unit’s defrost drain can be blocked by food particles or other debris, and is typically accessible from inside your freezer. You can try to flush the drain from inside the freezer using warm water, though you may need to remove debris manually. Locate the defrost drain hose on the back of your refrigerator, and clean it with hot water and soap to remove any clogged debris.
Should you suspect your refrigerator’s water supply line is clogged or frozen, you should unplug the appliance and make sure its shut-off valve is closed. From there, examine the water supply line to see if there are any breaks or tears. If so, the line should be replaced. If you notice a clog that does not appear to be ice, consult with a refrigerator repair professional.
