IN CASE ANYONE ELSE IS SEARCHING AS i WAS EARLIER. In my machine you have to disassemble the top, front and back.
First the main heating element is accessessed from the rear. remove the dozen or so screws which hold the oval/almost figure of eight shaped cover. You can then see the rectangular heating element which is secured by a further 2 screws. The cables lead inside the machine and will not pull through even if you release the cable tie from outside the back of the machine (You'll see it move if you gently pull the cable).
Now remove the lid, then the control panel. then the panel below this - which includes hinges and door seal - lift off metal panel with the door then remove bolts which secure the panel underneath. Finally you can see the electrical cables which are towards the bottom, right of the machine at the back near the motor - you might need to vacuum out the machine - I did. (Below the drum on the right hand side as viewed from the front).
Replace the element and reassemble. Sorted!
