hello i have a sime friendly boiler and this has started to buzz/hum/whine very loudly especially when hot water is running but equally when the central heating is on.
this is not a pipe noise this is more of an electrical noise.
i took off the cover and in front on left ,right next to the button that ignites pilot light is a black box type thing with a wire coming off it .this is what seems to be buzzing does anyone know what this is and if they are expensive to replace???
