    Minore 2 - high bar pressure

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Has anyone had their expobar pushing 13 bar under extraction.
    Is it easy to fix? I havnt had it serviced, bought it 2nd hand 2yrs ago.
    If so, anyone around SE suburbs that can check it out?
    Thanks

    SE suburbs
    Why is it that every one assumes that *SE Suburbs is so easy to find in Darwin...

    An update as to your true location in ya profile might be a help..

    PS. If ya gauge is correct.... *Then any number of predictabilities on offer.

    Have you tried reducing the pressure on the OPV? When you remove the drip tray you will see a hole in the frame. Behind the hole should be a visble screw, which is the OPV. I was told when I purchased my Minore 3 (which is set at factory at 12 bar) if you turn it counter clockwise by about 700 degrees (almost 2 complete turns) it would be reduced to about 9 bar.

    As far as i understood the OPV on a minore is on the front face plate behind the drip tray, but I could be mistaken. it is simple adjustment if you know what your doing, if not take it in for service and make sure you point out this as a problem or you might just get seals replaced but they are probably due anyway if its gone 2 years or more on the originals
    hope this helps

    Sits at 2bar when resting,
    is it plumbed?
    if not at rest should it not be on zero? (gauge fault?)

    Twas thinking the same...

    Have seen the odd one that will drop to Zero with a tap and or if the brew switch is run again with an open head..

    Not critical, but need to remember that any values will just be an indicator and without a real gauge... All subjective.

    Re: Minore 2 - high bar pressure

    run a group head gauge over it.....

    Make your own for +-$25

    or

    Chris at TC once offered to let you do it for free # using his at his "shed", but you needed a spotless Ghead and ask nicely (buy some product?)
    #not sure if he still will?
