Over time and with heavier usage than normal domestic use, the door can eventually 'drop' a little due to hinge movement. The door is fully adjustable with this hinge so it can be fixed. The bottom hinge is the one that you need to access, the fridge is best to be emptied and placed 'on its back' to do this, as you need to access under the unit to remove bottom grill. Be careful with the self closing function as it has a little pressure on the hinge, if you undo all screws it is difficult to put back, you only need to loosen the screws in order to reposition the door by adjusting hinge.
