Thermador Refrigerator leaking water
If your Thermador refrigerator is leaking water onto the floor, start with the most likely cause: a clogged or frozen defrost drain. When that drain freezes or clogs the defrost water can overflow the drain trough and run down into the cabinet. Thaw any ice, then flush the defrost drain with hot water to clear debris. If the drain is clear, check the door gasket next; a torn or missealed gasket lets warm, humid air in and causes condensation that can leak out between the gasket and frame. Also inspect the water tank assembly for cracks or hairline leaks — replace the tank rather than trying to glue it. Examine the water inlet valve for cracks or loose fittings and confirm the supply line is tight, and check the water filter housing and filter head for cracked plastic or damaged seals. These parts are common causes when a fridge is leaking water or a refrigerator is leaking water on the floor.

01 - Clogged or Freezing Defrost Drain
If the defrost drain is frozen, the water will overflow the drain trough and drip down to the bottom of the compartment. This water can eventually leak onto the floor. Check the defrost drain to determine if it is clogged or frozen. If the defrost drain is frozen, thaw the ice. In addition, flush the drain with hot water to ensure that it is clear of debris.

02 - Thermador Refrigerator Door Gasket
If a refrigerator is leaking water outside the appliance, it's possible a door gasket is damaged. A door gasket that does not form a proper seal to the refrigerator frame will allow warm humid air to enter the refrigerator or freezer compartment. This can create condensation which can then leak out the gap between the gasket and frame onto the floor. You should inspect the door gasket for any tears or twists and replace the gasket if necessary.

03 - Thermador Refrigerator Water Tank Assembly
Inspect the water tank assembly for any leaks. Be aware that the leak may be very small and hard to find. If you discover a leak, replace the water tank. Do not attempt to repair the water tank—glue will not stick properly to the plastic of the tank.
Highly Likely
04 - Thermador Refrigerator Water Inlet Valve
The water inlet valve opens to supply water to the dispenser and icemaker. If the water inlet valve is cracked or has a loose fitting, water will leak from the valve. Inspect the water inlet valve for cracks, and make sure that it is tightly secured to the water supply line.
Highly Likely
05 - Thermador Refrigerator Water Filter Housing
Inspect the water filter housing for cracks. If you discover any cracks in the water filter housing, replace the housing.
Highly Likely
06 - Thermador Refrigerator Water Filter Head
The water filter head might be cracked, or the seal may be torn or missing. Inspect the water filter housing for cracks. If you discover any cracks in the water filter housing, replace it.
