If your kettles leaking the only thing you can do is make sure all the screws are tight. The manufacturers now stop you getting into their appliances by fitting the odd special fixing. If you are handy with a drill you can drill out the fixings and make your repair. Its often very simple and obvious what is wrong and if you muck up your kettle or toaster then you have'nt lost much as getting it repaired is a rip off anyway. You might as well go and buy a new one.
