boiler pressure

[kowalski181]

wondered if anyone knew much about the worcester greenstar 30si increasing the pressure on it. we have had a few problems with a new bathroom installed, new towel rail and some of the radiators needed bleeding. hot water when the pressure is below 1 doesnt work properly just goes on and off, but after bleeding radiators it is now slightly above won and hot water working fine
just wondered how one would increase the pressure on our boiler. it comes with a key that you press up into the boiler and when it is locked in you turn the hexagonal thing next to it anticlockwise to increase pressure. however when i have done it it has only increased very slightly and water came out meaning i could not turn it all the way anticlockwise as a lot came out
does the pressure increase heavily straight away or is it a gradual thing for a good few minutes? anyone help
cheers

well i guess it could increase pretty quick depends on how far you open the inlet valve, but as you turn you should hear water passing into the system , i prefer to ease it in slowly lol it shouldnt take minutes just a few seconds

theres something not quite right i had it on for about 5 minutes and think it moved a little, mustnt have the key in the right place to start the pressure when turn the valve when its in place
