A number of things can be the source of the water leak in your refrigerator including: water line fittings, water valves or the refrigerator is not level. If the icemaker is leaking water, switch off the water supply to your icemaker.
it could NOT be the ice maker at all. when we had too much weight in our freezer, the bottom bowed out and let the water get between the bottom of the freezer and the insulation layer. when the ice built up, the water leaked down into the bottom. it had nothing to do with the ice maker. we removed the weight and "fixed" the problem.
