I have tightened them. The right one was loose but is now tight. The door still falls off.
The hinge just slides off the frame. It is though the toe of the hinge is not catching underneath something. Looking through the slot I cannot see any difference between the left and right interiors. Probing with a small screwdriver feels the same.
The E-Nr number is XXXXX
Thanks - job for tomorrow as cooking now using top oven. Will let you know.
Door is now fixed. Problem was a broken latching point in the hinge receiver. Fixed with a bolt. Actually swapped hinge receivers in top and bottom ovens so that weakened receiver now carrying less weight.
Was shocked how many screws used to fix ovens sides together. Not the easiest to open especially as hinge receiver also held in by screw through bottom frame.
Thanks for your help.
