Cheers Don. I use deionised water so limescale shouldn’t be an issue although I did try descaling anyway. No joy. It looks like a new iron for us.
I agree with the comment about disposable items. Nothing is made for repair nowadays and I’m an engineer which makes it very frustrating as quite often one will know how to fix something but can’t get in without smashing the case as there are no screws. Don’t get me on mobile phones and their batteries.
