You might consider using 170 degree hinges, which will allow the door to go further without damage, especially if the door is in a position where people can bump into it when they walk by. I use narrow, double doors to avoid that (e.g. two 300mm doors on a 600mm wall cab).
And maybe some kind of limiter? A piece of string?
John, thanks. Good ideas.
Door had definitely been opened way too far, pulling out the hinge.
May have been exacerbated by the door being closed against the large toblerone shown, putting a leveraging moment on the top hinge. Bottom hinge screw seating is ok.
The plasterwork had evidence of the door being squashed against the plaster corner when I saw it this morning. Lots of plaster flakes about the kitchen counter top.
Unit is mounted very slightly back, may be 1 - 2mm (more or less) from the wall that the door opens out against. Interestingly the lower hinge was more or less fine. I needed only to adjust that hinge to bring the line of the closed door in line with the cabinet line.
