We're in the process of moving into a new home and I've just noticed that the oven won't turn on.

It's a Simpson Neptune, and I believe the model number is 1U602W.

The elements on top of the oven heat up ok, but not inside the oven.  I've tried both bake and grill and the elements (both top and bottom) don't even get warm.

I'm guessing the oven is in automatic mode.  Does anyone know how to get it out of automatic?

There's an analogue clock with two buttons to the right of the clock.  The top button is marked "Start".  The bottom button has two icons, top icon looks like a little clock and the bottom icon looks like a pot with steam coming off it.  The bottom button can be pulled out and then when you turn the button the clock changes the time (hands move).

I've tried looking for a manual but without luck, the Simpson website only seems to have manuals for half a dozen ovens, probably just their latest models by the look of it.
