Refrigerator leaking water

Just bought a house and the refrigerator that came with the home is a Kitchenaid KSRA25PNSS00.

Turned the water on at the valve and the next day there was water all over my kitchen floor.

I checked all the accessible valve fittings and hoses and there are no noticeable leaks or water dripping; the drain pan was completely full however.

Played around some more and figured out that when you use the water dispenser; water flows into the drain pan as it dispenses water.

Anybody know how or what I need to do to correct this problem?
