Removing the microwave door

In many cases, microwave door panels are held together by hidden hooks or catches that ave to be separated by a thin, strong tool such as a putty knife. I've attached a photo that should serve as a good example.

It is helpful to have access to the spare parts diagram from the Neff website to visualise this procedure.
To work on the door it is best to remove it from the oven. With door partly open lift the whole door upward. The hinges slot freely into the body of the oven but are on very strong springs and it can take some effort to lift them clear of the body of the oven. Take care not to break the black plastic locking hooks.
Place the door on a flat surface front down, resting on the handle. The raised plastic back is clipped into place. Use a thin flexible tool to wriggle between the plastic back and main body of door, start on sides and bottom and gradually unclip. Once the sides and back are clear the top should come away easily. Note the part by the hinges is very thin and fragile.
Lifting away this back piece will reveal six small screws holding the microwave screen assembly to the front door panel. There are two larger screws that link through to the handle. Undo them all. The microwave screen assembly (which includes the hinges) is now attached to the front door panel with a series of fragile plastic clips hooking over the assembly. Gently ease these clips away, once the bottom clips are released the assembly should come away easily.
The microwave screen and glass door panels can now be cleaned, be gentle cleaning the microwave screen and ensure all is dry and smear free before reassembly.
The black plastic locking hooks can be replaced, these are attached to the microwave screen assembly with a spring and two hooks that slot into holes in the side of the microwave screen assembly.
To reassemble, reverse the procedure, ensuring that the panels are snapped back into place and screwed in securely.
To replace the reassembled door into the oven. The hinges need to be pulled back and held in that position but there will be a lot of resistance from the springs. Get a couple of medium size allen keys. Pull each hinge back to reveal a small gap between the hinge and the door assembly. Drop the shorter end of the allen keys into this gap, these should hold the hinge open while you fit it back into the main oven. Once the hinges are in the oven, with the door open still, retrieve the allen keys. If the door does not seem to want to shut the hinges are not fully located, try lifting the door and jiggling it to encourage the hinges to fully locate.
