This doesn't happen EVERY time, but it does often enough (every few days) to be annoying. It cuts off the electricity to all the power sockets in the house, by tripping the main RCD (or whatever it is called). Lights unaffected. What should I do? Or call a sparks?
Almost certainly you need to replace the oven element, it's usually a fairly simple job only needing a screwdriver. Just be very sure that you have isolated the cooker before you do it.
The insulation in oven elements often fails such that they trip the RCD, not seriously dangerous if your oven is properly earthed but will probably get worse so it trips the RCD *every* time you turn it on.
I had a similar scenario. Does it trip when the heating to the oven is switched on, and therefore likely to be the element, or when like mine it was just the oven light - ie first position on the oven switch in my case. Just to confuse everything, this wasn't the light that was faulty, but the fan motor, which didn't come on with the oven light but had the line switched through in the first position. One damnation of continental electrical design is that they tolerate using neutral switching to bring something up to power.
Whichever way, you're looking at for someone who does cookers, washing machines, etc rather than an electrician.
As the others have said it certainly sounds like it's an element on the way out - which one (fan/conventional oven, grill etc) of course depends on at what point on the dial the trip occurs.
It's certainly a DIYable task - have a look at some of the videos as
