If it is a fan oven,switch off electric,remove the 6 phillips screws from the rear access panel in the oven to reveal the element,only 1 screw holds this in place.Before removing element,remove the rear cover of the oven (with small allen key)remove wires from the element connectors and note which colour fits on to each connector.Replace with new element and reassemble.
I have just done the same job but neglected to note wiring sequence,so if you can help me on that ,you will see my NEFF cooker question on the question page.Thanks.Dave
