Hoping someone can help ? I've got a biasi HE combi boiler that keeps making a rattling noise every time we switch it on. It heats up and get to the heat limit then starts rattling and vibrating. It will stop when it's not heating up and when it starting heating up again it starts. The funny thing is I,ve got a ensuite bathroom when a use the shower Or the tap in there it doesn't make a sound never has. When I use the main bathroom it rattles and vibrates, kitchen and central heating it makes noise. I tried to get someone to look at it and it wouldnt make the noise. can someone tell me what it maybe ?
