this ones puzzling me , the boiler has power, the two zone valves operate fine and the pump runs. the boiler has row of lights on it. the boiler on light is lit as is the pilot light one. but the pilot is not actually in flame. the boiler doesnt fire up. when it used to fire up the radiators and hot water would only get warm and then shut off. now it doesnt fire up at all. i have tried the overheat reset and still nothing. any offers?
