Hi,
About 30 seconds after my central heating kicks in from cold, I get a really loud whining/vibrating sound coming somewhere from the inside of the boiler.
I have recently replaced the expansion vessel, the diverter valve and the pump, but it is still making the same noise.
It is exceptionally loud - so much so that I cant hear exactly where it is coming from as it vibrates through the whole boiler.
Does anyone have any advice?
Thanks
