Fairly simple to do - get the triple ring element when you buy a new one. Isolate the power, remove the back panel, and remove the trays from the oven.
From the back of the oven, just to the right of the main central fan, remove the 2 screws and 3 electrical spades on the element (take note where each wire goes). Remove panel inside the back of the main oven and slide the element out. Replace element and secure 2 two screws to hold it in place. You may need to twist slightly to find screw holes. Once element is in place, replace cover in the oven and the panel on the back.... job done. Hope it helps
