Hmmmm...
I have a Beko DC212W and the answer is NOT to undo any screws .
If yours is similar to mine insert a screwdriver between the bottom cooker bracket and the door and twist it.(Just below the hinge)
Then lift the door and gently pull it ouy(Watch out it is quite heavy)
you can then fix the hinge and rebuild following the instructions above in reverse..

Could you please tell me if anyone had any idea for your problem, we have same cooker and same problem! Would appreciate any feedback from you.
