There is no reset button. If they are faulty then you must find the fault & repair it. Turn it on, press start & leave it trying to start. It should eventually go in to fault mode & start beeping. When it beeps take note of which lights are on & which are off along the top row. Write them down exactly from left to right and post the result back here. The fault code should come up within a couple of minutes. So I am not telling you to leave for half an hour or so.
