Hi All,
I have an old Vokera Excel boiler which was working fine until about a week ago.
Now, if the boiler is switched 'on' but is not providing central heating or hot water eg. in standby, it makes a banging/scraping/shuddering noise.
When you switch the central heating on (on the boiler) or run a hot water tap or the shower, the noise stops and the boiler quite happily produces hot water.
The noise also stops when the boiler is switched off (as it is now).
I don't do DIY but I'm suspecting this might be something to do with water pressure? Help!

NB: Pressure is currently at 2.5 bar on the guage.
