My fridge door has dropped and won't close?

My Scandinova LFA374W fridge door has dropped and won't close. If I empty everything out of the door compartments and lift door, it will then close, but I can't keep doing this. There is a hinge at the top right hand side of the door, the door seems to have slipped down the hinge once open, but I can't see how you get to the hinge to tighten a screw to fix the problem. I've looked at spare part websites, but they don't seem to carry a hinge for this make of fridge. Any idea what I can do?
