It’s not unusual for a refrigerator to drip a little water on the floor after you replace the water filter—air trapped in the water dispenser system can make the water dispenser drip enough to overflow the drip tray below the dispenser. You can fix it by streaming a gallon or two of water through the dispenser to eliminate the trapped air.
If water drips on the floor from the back of the refrigerator, a leaking water inlet valve or cracked water system tubing could be the cause. A clogged or cracked defrost drain tube could also cause the leak. Defrost condensate water collects in the drain pan at the bottom of the refrigerator so a cracked or overflowing drain pan can also cause water to drip on the floor behind the refrigerator. Check the drain pan for cracks and clean out any foreign objects that may be inside the drain pan.
Excessive frost caused by a leaking door seal can also cause the defrost drain pan to overflow. If you see the refrigerator drain pan full of water and overflowing, check the door gaskets and replace them if damaged.
These repairs may help solve your refrigerator problem
Replace the refrigerator water inlet valve
The water inlet valve assembly of the refrigerator controls water flow to the ice maker and the water dispenser. Replace the water inlet valve if it doesn’t open or shut off the flow of water properly.
