ok. would you mind posting an image with the wires pulled off the terminals on the heating element so i can see if the terminals are protruding 'on axis' from the ceramic insulating sleeves. you will probably need to take images from plan view and side elevation to confirm this.
in other words there must be a crack in one of the ceramic insulators for the current leakage to occur, and for that to be the case i would expect one of the terminals has been bent off axis, resulting in the ceramic insulating sleeve cracking
The element has arrived. While trying to get the socket onto the old element, I've found that the thick black power cord gets in the way and there's no way to bend it enough to make enough space. I'd like to simply remove it but there is a black part that holds it in place on the chassis. Is there a good way to remove it? Ideally without destroying it?
im not saying you are wrong, but it will be the first machine in the history of londinium where the power cord has needed to be removed to change the heating element; we even put that recess in the frame specifically to accommodate the element change
when your 38mm socket arrives get physical with it and use the socket to simply push the power cord out of your way; most like to the left, towards the front panel i would expect. it will move. the socket has rounded edges and will not cut or damage the cable
im happy to assist via FaceTime or whatsapp
you really dont want to have to remove the cable gland, its a real pain (you ideally need a cable gland tool) and to the best of my knowledge no one has ever needed to
On further experimentation I think that the problem is that the recess in the chassis is not fully aligned with the element, and my socket is a deep cylinder shape. The front corner of the recess is in the way. I see in your pictures that yours is not as long so that it's narrow at the point where it reaches the chassis. I'll probably need to find a smaller 38mm socket.
