I have a slide and hide oven door model. All was well until the oven light bulb stopped working, it should be a simple task to replace it but it is impossible to remove the glass cover and this is an ongoing problem which Nef are well aware of. They sent me a leverage tool to fit(price £8.40) over the glass shade advised me to heat the oven for twenty minutes at 200 degeees and see if that did the trick. No such luck sent the tool back(postage £3.49 not refunded) The only solution they could come up with was to send an engineer out to replace the bulb at a cost £106 plus parts which is a complete rip off just to replace a bulb. It’s obvious that there is a serious design fault and having read reviews on the subject there are many others having the same problem. My advice don’t buy this oven unless you are prepared to be ripped off when you have to replace the oven light.
