Thermador Dishwasher dispenser not dispensing soap
If your Thermador dishwasher soap dispenser is not opening, the problem is usually a broken dispenser lever, a damaged detergent dispenser cover, or another failed dispenser part that keeps the door from releasing during the cycle. On this Thermador dishwasher dispenser not dispensing soap issue, start by checking the dispenser lever first, since it is the most common cause, then inspect the detergent dispenser cover, detergent container, and dispenser lid for cracks, warping, or anything that keeps the detergent door from moving freely. If those parts look good, the complete detergent dispenser may need to be replaced. A faulty control board can also keep the dishwasher detergent dispenser not working, but that is much less likely and should be checked only after the dispenser components themselves. If your dishwasher not dispensing soap leaves detergent sitting in the cup or the dishwasher detergent door not opening, matching the exact part to your machine matters.

The control board provides power to nearly every component of the dishwasher. If there is a problem with the control board, it might not send voltage to the detergent dispenser, preventing the dispenser from opening. However, this is not likely the case. Control boards are often misdiagnosed—make sure you check more commonly defective parts before replacing the control board
