I took the dishwasher apart again. I have taken the hinge off, but you can't see it's crooked or worn anywhere. I noticed that the plate on which the hinge is attached is 3 mm too far back in relation to the other side.
If they were at the same distance, in my opinion it would be ok. Only the metal plate from what I can see is not regulated. There are two screws at the bottom of the torx, but once you unscrew them you can't move it.
