turned the wrong valve on ideal logic 35 combi boiler

Put it on ,and go take a look.
If pressure rises to 3 bar ,the relief valve will open and dump water out of the system

hey all,

we moved into our home in August last year and we got our boiler serviced right away (10 years old) with no faults noted. however when the days started to get cooler we started noticing that our boiler would lose pressure.

we called some folk round and they've not noticed anything jarringly wrong with it, so we've been re-pressurising it ourselves. however yesterday morning i realised id turned the wrong valve/tap and now it seems to have made it not hold any pressure for longer than 10 minutes.


i accidentally turned the tap right next to the pressure gauge and i can't figure out what this is for! i've tried googling, image searching, etc, and no hints as to what it's for, not even in the manual. any help would be appreciated - can we fix this problem ourselves or is this unfixable?

thanks!

Does the pressure go all the way to 0 bar?

I see the pressure is on 2 bar in the photo, is that with the heating on?

There's no visible dripping on the boiler. We don't have a copper pipe but we have a vent? yesterday was dripping water but today there is steam.

Can you give more details of this "vent"? What does it look like? Picture of where the steam is coming from?

Usually 15mm copper pipe, a meter or so below the boiler flue outlet (assuming standard horizontal flue)
