    Two weeks back I noticed the boiler had an E0 error message.
    On checking further, the pressure had complete dropped into the red area.
    I re-pressurised the boiler to near the 2 mark and 2 weeks later the pressured is half way between 1 and 2.
    Is this because there may be a small leak in one of the pipes or down to something else?
    Anything I can do prior to calling out a plumber?
    I was hoping to call out a plumber during summer 2021 for the yearly service and for a few other jobs, so if possible this could wait and not urgent, until then it would be better for us.

    Water is leaking out somewhere ,either from the boiler or from the systems rads/ Pipework etc.
    What does pressure rise to when heating has been on for an hour ?
    Your pressure ,when boiler is cold ,should only be around 1 bar.
