Hello all,
I have a Worcester 28SiII which has started making a loud whistling noise. The boiler is 3 years old. I first noticed the noise after the timer had just turned the heating off. I turned on a hot tap and the boiler lit and the noise stopped but as soon as I turned the hot tap off the whistling started again. I also noticed that when I turned on a cold tap the noise from the boiler also stopped, only to come back as soon as the cold tap was turned off. I tried turning off the boiler completely but the noise persisted. Then I turned off the cold water inlet on the boiler and the noise stopped. So since then I have left the cold water inlet on the boiler turned off, the heating still works fine but obviously I can't get hot water! With the cold water supply turned on and the central heating OFF the noise is constant and loud, with the central heating ON the noise is intermittent and quieter.
Has anyone come across this problem before or have any idea what could be causing it?
Thanks.
