On the bottom of the case of my potterton boiler is a reset button. In the past it has occasionally "popped out" and needs to be pressed in again to allow the boiler to operate. Recently this has become a frequent occurence and a nuisance.
I have never understood what it is protecting- what causes it to cut out- but now I need to !
Can anyone please help?
