how can i fix my indesit wd10?

My WD10 Doesn't dry any more... I have had a brief look inside and there is no element reset switch that I can see. having seen other blogs I suspect that it may be one of several problems: heater, heater fan, element, etc etc. what i really need is a magic wand as I am totally fed up with having to fix this sort of poorly made stuff (ooh it makes me mad)..... So, if there are any Wizards (with Indesit knowledge) who can help. I would be most grateful. cheers.
