Bosch freestanding oven left on overnight, nothing working now

[Minisaurus]

Hello forum,
My daughter sneaked up in the night, used the oven, left it on, circa 70 degrees.

Now nothing really works - the hob plates do get slightly warm, and the indicator lights aren’t working properly.

Any ideas where to start?

I could upload an appliance circuit diagram later, if that helps.

I found the problem - the oven is 3-phase, and the fuse in phase 2 had blown. Replacing this fixed the problem; I guess it was the fact I was getting some warmth from the plates that threw me. Last time she did this, the RCB (?) tripped when the top element burnt out; lucky escape this time. I’m looking into some kind of a timer now ...

Or a new home for your daughter.
