IA detergent dispenser holds the detergent and the rinse aid, and controls when they enter the dishwasher during the cycle. The door is spring-loaded and can become damaged, it can become stuck either in the open or the closed position, or the mechanism which controls it can fail.
So the first thing you want to check is the lid, which should pop open easily with a flat-head screwdriver. Under the lid check for any physical damages and check the spring and tripping mechanism which pokes out when the lid is in the closed position. Also check that the spring is connected to both the lid and the mechanism.
The lid itself is very easy to replace, it simply clicks into place and it can be bought separately as a spare. The spring, again, is very easy to replace as it can be done while the unit is still in the door.
The tripping mechanism, however, you need to remove the unit because you need to get to the underneath the complete unit. In most Bosch dishwashers the spring and the tripping mechanism are brought together as a kit.
So if these all appear to be in working order and you still have a problem, then it's likely to be due to the mechanism of the actual unit itself so you'll need to replace the whole thing. Likewise, if there's a problem with the dispensing of the rinse aid, then you'll need to replace the whole unit.
This video shows an example on how to remove or replace the part on a typical machine, some models may be different but the procedure should be similar.
