How can I fix my Electrolux EOB5630X oven?

Hi

This evening, my Electrolux EOB5630X oven stopped working. It was switched on and after a few minutes blew - there was a small bang and the main fuse (at the box) tripped. On resetting the fuses, there is power to the oven and the digital display works. However, the oven itself doesn't work at all - the element doesn't heat, the fan doesn't work and the light doesn't come on.

I've taken off the front top plate, and there's no obvious sign that anything's blown there.

Any ideas, or is this one for the electrician?

Cheers

James
