If your Thermador coffee maker is leaking behind the dispenser, start by checking the tube or hose that feeds the brewer — a cracked or pinholed hose is the most common cause of a refrigerator coffee maker leaking and will send water where it should not go. If the hoses and container look solid, verify the water inlet or dispensing valve and the control board or control board assembly next; a stuck valve or a control board that keeps sending voltage can let water flow continuously. Also check the K-Cup pins and piercing mechanism — a pod that is not pierced or clogged pins will let water spill instead of flowing through the pod. Less commonly, a cracked coffee maker container or a damaged door assembly can cause leakage, so inspect the container for hairline cracks and the door for damage before replacing major components.

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.
03 - Thermador Refrigerator Control Board Assembly
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.

05 - Thermador Refrigerator Control Board
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 continuing to allow voltage to be sent to the water inlet valve, keeping the valve open. You can inspect the control board 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 inlet valve is functioning normally before considering a control board replacement.
The most likely cause of a refrigerator coffee maker leaking is a damaged container. Inspect the coffee maker container for any cracks or holes and replace if required.
