All of this can be done with the oven in situ. Take the back off if you like, but its un-necessary, dirty and time consuming. So here we go: Power off at mains. Remove 4 screws holding plate which guards the fan. You will be faced with the fan partially obscuring the top element retaining screw. At the centre of the fan spindle is a reverse threaded nut. WD40 the nut. Wait a minute or so and using a socket wrench and a flick of the wrist, the reverse thread nut should losen v easily. Having mastered the lock nut, tap the washer and it should become loose enough to remove by hand. If not, it just needs a little gentle persuasion with a flat head screwdriver where it sits on the fan itself. The grime will loosen and it will pop off. Squirt some WD40 onto the fan spindle, and wait a couple of minutes. Ignore any advice to lock onto the threaded spindle because if you damage it, your relatively cheap repair will become pretty expensive. Simply use a locking mole grip on the fan itself where the locking nut sits against it and pull and twist gently away from the spindle. You will be surprised how easy this is. Very little chance of damage. You can then access all 5 element retaining screws. Gently lever out the left foot of the element from the oven housing. Remove the spade connectors from the old element. Reversal of these instructions to fit the new element. Restore mains power. Reset clock or main oven will not work.

If you can see the element once you have removed the inside rear panel, then remove any screws that you can see, and ease the element forward, pull the wires off, but do not let them slip behind the rear wall of the oven, or it means removing the whole oven, to fit the wires back on.
If you cannot see the screws, or they are fastened from the rear, then it will have to come out of the housing.
Hope this helps.

Ha - I found the solution myself. You need to remove the 3 screws securing the fan motor. Once you've done this, you can wiggle the fan a few mm, far enough to be able to remove the top element screw.

Hi Steve...yes, these are a pain! Remove the centre fan nut (which is anti-threaded) then lever off the small locating washer underneath. If you are lucky, you will be able to now pull the fan blade off of the motor shaft. However, very often they won't budge!. If you try to knock it off, it is so easy to damage the fan motor (about £80!!). It is possible to leave the top bracket screwed to the oven and unclamp the element from it. I have come across three different typed of clamps so far. One is very easy to do. You can then remove the clamp from the new element and once the element is in place, use the old clamp. It's a fiddle but quite do-able. I have also come across these where the top clamp has been previously removed altogether by engineers on previous repairs! Hope this all helps a little....

Hi. Hold the fan with your hand, and unscrew center nut, N.B It is a left hand thread, so unscrew it clockwise as though you were tightening it the conventional way, and vice versa for tightening it up.
Please `rate my solution.
Thanks.
P.S. You can bend the fan blade if needed.
