Thermador Dishwasher Bi-Metal
The bi-metal actuator is a metal loop which acts as a latch for the dispenser door. As electricity is applied to the bi-metal, it deforms and bends away from the latch, releasing it. If the bi-metal is burned out, it won’t release the dispenser door. To determine if the bi-metal has burned out, use a multimeter to test it for continuity. If the bi-metal does not have continuity, replace it. In addition, make sure that the dishwasher is getting enough water. If the water level is too low, the wash motor may not draw enough current through the bimetal, causing the bimetal not to bend enough to work properly.
Thermador Dishwasher Dispenser Slide
If the dispenser slide is damaged, the dispenser won’t open or close properly. If the slide is broken or damaged, replace it.
Thermador Dishwasher Pump and Motor Assembly
The dishwasher’s pump and motor assembly circulates the water through the wash arms during the wash and rinse cycles. If the pump and motor assembly is defective, the wash cycle may be interrupted and the dispenser will not be activated to release the detergent. In this case, the pump and motor assembly will need to be replaced.
Improper loading
There needs to be adequate space between the dishes and the dispenser. Inadquate space can prevent the dispenser door from opening or prevent water from mixing with the detergent. If a large item is placed in front of the dispenser the detergent will not get rinsed out properly. Leave some space between the dishes and don’t place large plates or pans in front of the dispenser.
Thermador Dishwasher Water Inlet Valve
A dishwasher’s water inlet valve opens following a short drain cycle to fill the tank with water in preparation for the wash cycle. If the inlet valve is faulty and the tank does not fill, the wash cycle may be interrupted and the dispenser will not be activated to release the detergent. In this case, the water inlet valve will need to be replaced.
Thermador Dishwasher Main Control Board
The main control board provides power to nearly every component of the dishwasher. If there is a problem with the main 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 main control board.
