ignore id**t above. system pressure on sealed system should be 1 bar when cold. anything near 3 and safety valve could discharge as well as leak out of any suspect pipework. system pressure gauge could be blocked. should be a silver filling loop that connects from cold water inlet on boiler to heating return pipe under boiler, open valve or valves slowly until pressure at 1-1.5 bar then reset boiler. if no good call engineer.

there's a few taps underneath the boiler is it the blue one ? do i just turn it and leave it ? is there any propper way i should do this ?

cant fix it completely but i had the same problem. you need to repressurise the system. there should be a tap to release water into the system. you want it around 2.5 - 3 bar
