Hi I am new to this forum. I am having difficulty with my boiler (details above). It makes a loud buzzing noise that builds in intensity before suddenly stopping. It appears to be random in occurrence and having been next to the machine when it did this the noise appears to be coming from within the boiler itself and it is accompanied by quite a vigorous vibration. I have bled the radiators and all are fine and working well. I am wondering if there is a problem with the accumulator or something - does anyone have any ideas? I am a bit stumped. Thanks in advance. CF
