we have a neff oven, and when ever i turn it on with the function selector it trips all the elctrics off in the house , the tempetature selector doesnt make anything trip off , we have tried disconnecting the fan and switching it on and it still trips all the electics off.. any ideas as to what it could be please?

contacts on the selector switch could be welded or you have a heating element down to earth
