If your Gaggenau refrigerator coffee maker is leaking, start by checking the coffee container for cracks or holes — the page notes a damaged container is the most likely culprit. Next inspect the hoses and tubing behind the dispenser for splits or pinholes that allow water to escape. A faulty control board or control board assembly can also cause leaks by continuously energizing the water inlet or dispensing valve and letting water run, so look for burned components and confirm the valve is closing. Common, easy fixes include a K-Cup that was not pierced or clogged brew pins; clean the pins with a paper clip and reseat the pod. A damaged door assembly is less common but can contribute if it misaligns or cracks around the dispenser. Whether you’re chasing a refrigerator leaking water behind the dispenser or a general fridge leaking water issue, inspect these parts in that order, and enter your model number on RepairClinic.com to find the exact replacement hose, container, valve, control board, or other part you need.

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.
