go to dualit web site, click 'support' at top of page, click on 'toasters' click on faq's, then select drop down text under heading "spare parts", there is a phone number to the factory spares dept, you can ask advice then either buy spares to diy or send in for estimate for repair, simples....I diyed mine which burst into flame, bought new elements and fitted them, plus requested and received wiring diagram, super cool company, Cheers.
