How can I reduce the pressure in my Ariston boiler?

I know that to increase the pressure I must open left valve then right valve until pressure rises - BUT - my problem is that the boiler pressure has gone up and is now too high - opening valves does not reduce it - how do I reduce the pressure?

Go to any rad and bleed it until the presser is down, may take a bit of time, good luck

Although it takes a little time, the easiest way is to release water via the radiator bleed valves...there are other ways, but this is the least messy. Just be patient!
