Hi the boiler cuts out on overheat mainly because of a faulty pump or air/lack of water in the system.Check your pump, feel the front , if its red hot it has most likely siezed. You can open the pump bleed screw on the pump face and insert a screwdriver lightly into it. You should feel the impeller spinning and you should not be able to stop it.For air, bleed all the radiators and check for bleed valves on the pipe work in the hot water cyl
