Had same kind of problem with a Creda Concept. Removed the rear back panel inside the oven, held by four screws. Cover of oven light had to be removed, used a flexable bottle top wrench as the heat had made it quite hard to remove. Removed the round heating element (only held by two screws) at the rear of the oven and checked it with a meter it was u/s.
Picked up an element from Plug and Socket for about £20. This may not be your problem but it is the easiest one to eliminate. If you check your element and it is ok, you then know that you have to look somewhere else. Hope this is useful.
