    Frustrating channelling problem - Breville Oracle

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Greetings folks
    I have 2 oracle machines - 1 for work and another at home
    The work machine has developed a frustrating channelling issue - it extracts fine after pre-infusion then blonds and runs watery (at 11 sec overall)
    All settings are identical - temp, pre-infusion time etc
    Beans are fine - perfect extraction in home machine
    Puck from channelled extraction looks similar however is dry in the middle - changed baskets between 2 machines but problem persists
    Have fiddled with the grind with no success, backflushed to make sure screen is clean
    Auto tamp seems ok - (2 machines are in separate locations so can't really confirm tamp from one to the other)
    Actually manual tamped to see if that made a difference with no success
    Dose seems the same with both machines (haven't weighed however)
    Any suggestions ??

    Were the beans brewed at home brought home from work and brewed the same day? If not try doing some that way and see how they brew.

    Drop the screen and clean behind it if you havenít already. Maybe an issue there with a part of it blocked forcing water thru a smaller area?

    I also have two Oracles, one at work and one at home, and while I haven't had your exact issue the home machine is much more temperamental than the work one. Is it just you using it? There's not much you can do to these machines I don't think in terms of abuse but are other staff etc using it?
