Dear appliance guy: Not only was your information incorrect, I broke the actuator on the door of the dishwasher when I tried to follow your instructions. In fact, it was very simple to open the door and most newer dishwashers are easy to open, too.
Just for you own information, I am a mechanical engineer so this task was not too "complex" for me. I didn't look very closely at the mechanism before I went on-line and to see if there was some "trick" to this. Had I taken a flashlight and looked at how the unit worked I could have opened it with a pen knife! My bad.
