I can't get the hot water to shut off by the timer swich the light is still on but the boiler is still igniting the pilote light and heating the water the swich is off? the controller box on the pipe isnt' turning off the system have to maually turn the lever to shut it off but now it is making a banging noise through the pipes down to the boiler and to the tank. like airlocks
