Have you checked both elements? As usually when you get a fault like this its one of the elements thats faulty.
As in these theres an element at the top and an element at the bottom.
Check the resistance of both elements and if one of them is faulty then it needs to be replaced.
Check them and see what you find. If you need anymore info just get back to me.
The electronic module is turning off the elements prematurely. There are two electronic modules on this appliance, the power module and the programme module.
Ok if its doing this then its a control board fault. But i dont have a wiring diagram on these to see how its powered up.
So i will opt out and if another expert can help they will jump in.
