I had a Maytag MBF1958WEW1 bottom freezer refridgerator. There is ice in the bottom of the freezer compartment and leaks from time to time. I'm guessing a drain line is plugged somewhere. The unit is less than 1 yr old.

the drain tube is clogged or maybe frozen, remove the restriction and you will have no more problem

• then you can check the water supply to make sure it is turned on, sometimes when houses are vacant they turn the water off as a precaution. the valve may be behind the refrigerator or under the sink in the kitchen.

remove back panel inside freezer. you will see drain tray at bottom with a drain hole in the middle - this is blocked usually with ice. melt off with a hairdryer and follow up with hot water till water flows away freely

SOURCE: water drains from freezer compartment into refridgerator

If the freezer is on top then empty out the freezer and remove the bottom and back liner of the freezer compartment usually phillips screws. In the back you will see the freezer coils along with a defrost element. Below these two items u will see a drip tray that collects water from the coils on defrost cycle, in the center of the pan will be a drain hole that connects to a hose that leads to a pan under the refrigerator.Normally the water is collected there and evaporated. The hole in the tray in the freezer is clogged. Thaw it and clean it until you can pour water in it and it goes to the pan down below. please rate me
