My B1430 oven door wouldn't close properly and I got round this by :-
1. Remove door.
2. Remove hinge securing screw LH & RH - about 40 mm above hinges.
3. Push each hinge assy so you can fit a couple of spring washers between the hinge and the oven frame.
4. replace securing screws and tighten.
This will reposition the hinge assy further back from the front face, thus ensuring a good fit on the door seal.
