Customer Questions and Answers for Detergent Lid by Bosch

Francis, What you don't see in the video is the mechanical latch and switch that activate and unlatch the door to allow the spring to slide the detergent door over and open. The detergent dispenser 00490467 is mounted to the door liner, and the mechanical devices are on the back side and positioned between the inner and outer door liners. When the control calls to dispense the detergent, power is applied to the switch and the switch moves the latch and unlocks the door and it slides open. in the rinse cycle the same switch is activated and it in turns activates the plunger for the rinse agent, and it is dispensed. At the end of the cycle everything resets, when you load in the detergent, and slide the door closed, the latch catches the door and it is set and ready to open when the control gets to the increment to release the detergent.
