at the top right go into instruction manuals at type in the E-number which you will get off the top of your dishwaher door. That should give a diagram.
Other wise if its similar to my NEFF model you will need a star shaped headed remover (can get as part of some drill/driver set at DIY stores). Undo the far left and far right screws on the top of the metal part of the inside of the dishwasher door, and then second down left and right on the inside of the dishwasher door, these are long screws which go through into the wood. (The other screws which look the same are much shorter and do not attach to the wood). Then carefully put the door up right again, and lift the door facia up from the bottom and pull out from the top. Then you can get to the screws for the handle.
