The Samsung side by side fridges are a real pain in the behind. Mine was leaking but not a constant pool on the floor. I looked it up and found a few videos about why. Took it apart and saw that the tray at bottom of either side will ice up and the defrosting will help but it will still ice up. 2nd time it leaked, look up more videos, found that the way to fix it is to wrap a wire around the heating element and extend it down the drain hose a few inches so that it will not freeze up at the drain pan. Also found that you have to leave enough room for the air vents so no stuffing the freezer. It hasn't leaked in the 2 years since I "fixed" it. Knock on wood!
