How do I fix my hotpoint aquarius door hinge?

Pins on my door hinge are broken - so I bought the spare part and took the door off (actually it fell off) undid the screws on the inside of the dryer but the door won't come apart to replace the hinge. Hotpoint won't tell me how as they say they will become liable for any damage I do to the dryer!!!

Any ideas - I don;t want to force the wrong part....
