hi there,my main boiler has just started to whistle loudly when the bath tap is put on ? the funny thing is if i turn the tap down low it stops making the noise, all the other taps are fine. heating works fine ,and no change in pressure,working at 1.5 bar with no warning codes showing.? it sounds like a very very loud whisting kettle.someone must have an idea? please.
