My cooker is a range cooker with a four ring induction hob. There seems to be something badly wrong. As I have said previously I have never used the boost function and am always pleasantly pleased with the speed of boiling water as this replaced a gas Range cooker, this is my comparison.. I shall have to try an experiment based on your videos. I am also amazed by the rather cluttered (to my mind) display on your AEG hob!
