Having a problem with a sirrus radiant gas combi boiler(lpg). Boiler operating ok on central heating mode but when you open a hot water tap the boiler is making a loud noise that phases out. The noise is I think is hydraulic and I think coming from the diverter valve. Is there any one familar with this boiler that have maybe come across this problem. Also doing the same when boiler is in hot water mode only.
