If the refrigerator is leaking water it's possible that the refrigerator has a clogged or freezing defrost drain. If the defrost drain freezes the defrost water will overflow the drain and drip down to the bottom of the compartment, If enough water accumulates in the bottom it can run out onto the floor. Thaw any ice that is clogging the drain. Make sure the drain is clear by flushing it with a turkey baster and HOT water.

If the refrigerator is leaking water the drain pan might be cracked. All self-defrosting refrigerators have a drain pan. The drain pan is underneath the refrigerator or near the compressor. When the refrigerator goes into the defrost cycle the frost and ice that is melted off of the evaporator coils flows down a small tube and into the drain pan below. The condenser fan blows warm air from the condenser coils across the top of the drain pan to evaporate the water quickly and so the drain pan never has to be emptied. However, if it cracks, the water from the defrost cycle will spill out of the pan onto the floor.
