Pete, the best way to go about this is to open it up, plug it in and using a multimeter follow the current from the mains cord to the heater to find out why no power is getting to the heating elements. However, if you are not used to working with 240VAC and don't feel comfortable with doing it don't even try as it is potentially lethal. In any case be certain the mains are unplugged before you open the case.
One can also try NOT plugging it in to the mains and using an ohmmeter to follow the connectivity, but this can be rather tricky. You may have to get professional help with this. It should not be rocket science, but it's much faster if you have some idea what you are doing. I suspect that many here are not familiar with this machine (at least I am not) so if you open it you might take some pictures and share them with us. Maybe someone will have an idea if they see the insides.
I just thought of something to check. There probably is an overheat switch in there, possibly on the heating element(s) it (them) selves. It could be a red button sticking out that you can depress and it will stay locked in. It might be somewhere else in the case, but it should be connected directly to the heating element(s).
Good luck and let us know how you get along or if you have any other questions. I suppose someone will attack me for my first suggestion, but that's ok.
