Hi, I know that these are known to be difficult to open. I have removed the glass dome cover, and I've removed the bulb, which disintegrated. Other bits of metal came away and I can't screw a new bulb back in. Seems there's no thread to screw a bulb in to anymore...?!
Many thanks for the answers, I was fearing a £99 callout charge from Neff. Had to try several implements, but a screwdriver of just the right size for the threaded section worked a treat. Thanks chaps !
