If the refrigerator defrost drain is clogged or frozen, water will fill the defrost drain and spill to the end of the compartment eventually spilling on to the floor. Check the defrost drain to determine if it’s obstructed or frozen. If the defrost drain is frozen, remove the ice; and clean the drain with hot water to make sure it’s free of residues.
Inspect the water tank assembly in search of leaks, bear in mind the leak may be very small and hard to find. If you find a leak, replace the tank. Do not try to repair the water tank; glue does not adhere properly to the plastic on the tank.

The head on the water filter may be cracked or the seal may be broken or missing. Inspect the water filter head for defects, and make sure that the filter is properly in place. If there are any cracks in the water filter head, replace it. If the filter seal is missing or broken replace it.
Refrigerators with automatic defrosting systems are equipped with a drain tray. The tray collects the water melted from the evaporator coils. To evaporate the water in the drain tray, the condenser fan blows heated air from the condenser coils to the top side of the drain tray. Because the ventilator in the condenser evaporates water on the drain tray, there is no need to empty the drain tray. However, if the drain tray is cracked it will leak as the defrost cycle is running. Inspect the tray for cracks, If the drain tray is cracked, replace it.
It is possible the water filter in not properly placed in the filter carcass. If the water filter is not properly placed, water from the filter may leak. Remove and re install the filter to make sure that it is properly installed.
