The drain pan is underneath the KitchenAid refrigerator, behind the bottom toe grill. Under most circumstances, this drain pan works well and requires no attention, but if water is leaking out of the bottom of the refrigerator, the drain pan might be responsible.
Disconnect power to the refrigerator first and then grab the toe grill by both hands and pull it out to remove. Reach inside and disconnect the drain pan, sliding the pan toward you.
Empty out the pan if it's full of water and reconnect. Look at the drain pan closely if the pan is not full of water but water on the floor.
Contact KitchenAid for a replacement if the pan is broken, split or otherwise damaged.
One possible source of water leaking onto the floor from the refrigerator is a clogged defrost drain, which is in the freezer compartment. Sometimes the drain is behind a plastic cover, which can be removed with a Philips screwdriver.
Combine hot water and baking soda and pour the mixture down the drain until the sound of water flowing is audible. If frost has covered the drain, clean away the frost with a warm, damp cloth.
Sometimes a water leak can come from the water line connection. Look behind the refrigerator and inspect the water supply line to ensure the line is not damaged or leaking.
Tighten the connections if necessary, including the supply valve connection and the refrigerator connection point, and ensure the tubing is fully inserted into the fittings. Contact a plumber or KitchenAid if the water line seems to be damaged or the connections seem incorrect.
If water drips down from the dispenser on the freezer door, the water on the floor might cause owners to think the water is coming from the bottom of the freezer. Check for ice cubes stuck in the dispenser and push them through the chute and hold glasses under the ice or water dispenser for an additional two to three seconds after dispensing is finished to allow for any drips.
