I bought a Neff U1452 cooker about four years ago. I've only used the fan function during that time. The top element, which is exposed, now has a nice coating of grease on it, so if I switch it on I almost immediately get a thick cloud of smoke!
Cleaning the rest of the cooker isn't too difficult, especially as the door is removable, but the top element and the wire cage it fits into is just too fiddly. If I could remove it, it would be much easier.
Is it easy to remove? It looks like the cage which holds it fixes by one screw at the front, and the rear support is just provided by the elements pushing into the back wall. I would have thought that elements do fail and it would be unreasonable to have remove and dismantle the cooker to replace them, so I'm hoping they are just a push fit into the back, but I'm loath to try to remove them until I know I'm doing the right thing.
