Hi Trevor,
Got it sorted thanks...
Managed to get the fan off too.! So for anyone else here's what I did...
1. Remove back plate inside the oven (4 spline screws)
2. Unbolt Fan. This bolt loosens opposite to normal (ie. turn Clockwise to loosen!). I used a medium screwdriver to stop te fan turning.
3. Prise washer off - note it's a keyed washer so only fits one way.
4. Remove Fan, which allows access to all screws. I found holding spindle with pliers and turning/easing the fan helped remove.
5. Unscrew element screws and carefully remove, taking care not to damage cable sheathing & replace new element.
Reverse procedures to re-fit, but watch keyed-washer is fitted correctly as this actually drives the fan blades.
Cheers,
