Thermador Refrigerator water dispenser not working
If your refrigerator water dispenser not working, start with the parts that fail most often. First check the dispenser actuator—the plastic paddle that trips the switch—because a cracked or worn actuator won’t engage the switch to send voltage to the dispenser. If the actuator looks fine, check for a frozen water tube in the door by disconnecting the tube at the bottom of the door and blowing air through it; blocked or frozen tubing is a common cause of a fridge water dispenser not working. Next inspect the water inlet valve and confirm house water pressure is at least 20 psi; test the valve with a multimeter for continuity and verify faucet flow to rule out low pressure. Also make sure the water filter is fully seated or replace it if overdue, and confirm the home shutoff valve feeding the fridge is fully open. If you need replacement parts, enter your model number on RepairClinic.com to see parts that fit your exact refrigerator and get the right actuator, inlet valve, tubing, or filter for the job.
01 - Thermador Refrigerator Dispenser Actuator
The dispenser actuator is the component that activates the switch or switches to send voltage to the dispenser. If the dispenser actuator is damaged, it may be unable to activate the switch. Inspect the dispenser actuator for any damage and replace with a new one if necessary.

02 - Water Tube in Door is Frozen
To determine if the water supply tube is frozen, disconnect the tube at the bottom of the door and blow air through it. If air does not pass through, this indicates that the water supply tube is frozen. If the water supply tube is frozen, thaw it out. In addition, ensure that the freezer is kept at the proper temperature. The freezer temperature should be kept from 0 to10 degrees Fahrenheit (-18 to -12 degrees Celsius). If the freezer is too cold, the water line may freeze.

03 - Thermador Refrigerator Water Inlet Valve
The water inlet valve opens to supply water to the dispenser. If the water inlet valve is defective, or if the water pressure is too low, the water valve will not open. The valve requires at least 20psi to function properly. Make sure that the water pressure to the valve is at least 20 psi. If the water pressure is sufficient, use a multimeter to test the water inlet valve for continuity. If the water inlet valve does not have continuity, replace it.

04 - Low Water Pressure from House Supply
The home may have insufficient water pressure. The water inlet valve requires strong water pressure to supply water to the water dispenser. You can check the water flow at the kitchen faucet to help determine if the home's water pressure is sufficient or not.
Highly Likely
05 - Misaligned water filter
Water filter may not be seated properly. Remove and reinstall the water filter. For optimal performance, refrigerator water filters should be replaced every six months or after 200-300 gallons (760-1150 liters) of water have been dispensed - whichever comes first. Replace the water filter if needed.
Highly Likely
06 - Home's water supply valve not fully open
The refrigerator is connected to a water supply valve that may not be fully open. If the water line was disconnected or the valve was shut off for service, it may not have been turned back on to the fully opened position.
Highly Likely
