If your refrigerator coffee maker is leaking water behind the dispenser, start by checking the small tubes and hoses—the most common cause is a cracked or pinholed hose that lets water drip where it should not. Less commonly a damaged door assembly can route water out of the dispenser area, and faulty electronics such as a failed control board or control board assembly can keep the water inlet valve energized so the coffee maker overfills. Also check the K-Cup pins and piercing mechanism; if a pod is not pierced or a pin is clogged, water can spill instead of flowing through the pod. Finally inspect the coffee container for cracks or holes. These checks—hose and container for visible damage, pins for clogging, and the inlet valve and control board for electrical faults—usually point you to the part that needs replacing.

Although it is not a common cause, a damaged door assembly could be causing the refrigerator coffee maker to leak. Inspect the door for any cracks or damage and replace if required.
If the refrigerator coffee maker is leaking, it's possible the coffee maker is dispensing too much water. This can be caused by a defective control board assembly continuing to allow voltage to be sent to the water dispensing valve, keeping the valve open. You can inspect the board assembly for signs of burning or a shorted-out component. You should first confirm there are no cracks or holes in the coffee maker container or hoses connected to the dispenser, as well as determine the dispensing valve is functioning normally before considering a control board assembly replacement.
If the K-Cup pod is not pushed down firmly, the lower pin may not pierce through the pod. If the pins are clogged or not piercing all the way through the K-Cup, water may leak from the coffee maker. If the upper or lower pins are clogged, they can be cleaned with a paper clip.
