How do I open the door?

The door on my kitchen aid under counter dishwasher is stuck closed. Most all my dishes are stuck inside. The lights come on and everything works fine but I can’t open the door.
Repair man wants a fortune to just come out. Can someone help PLEASE :eek:

I have the same problem with my Kitchen Aid. Trying to find a way to open the door since the plastic thing that unlocks it seems detached.
