I have an electric iron Russell habbs brand model no.18720. How can I disas?

For may years now electric irons have been made to be impossible to dismantle - it's a safety thing - they don't want users messing around and killing themselves. To disassemble an iron you will need to destroy it.

The consumer magazine Which recommends the Philips Azur iron for about £40

Good Luck...
