    Restricted Flow

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I have a Diadema machine which produces good shots however....often when I dose with what I believe to be the correct grind/tamp/dose, only one side of the dual pour group handle produces a flow of coffee. Something is preventing the flow from the other side of the pourer.
    The shot resulting from only one side is good ie) about 25-30 ml in 30 seconds, just annoying if I am making 2 coffees not to be able to have half in each cup direct from the handle/pourers.
    Anyone have any suggestions about what might cause this problem ?

    Gday Rowd,

    I think we all experience that occasionally. It can be things like debris in one spout, machine level and such or dosing and distribution, but more often than not, I find its caused by either grind being a tiny bit too fine or dose being a little greater than the pervious shot...

    Hope tthis helps...

    Thanks 2mcm,
    Yes, I thought maybe the grind was just a little too fine (maybe it was), however my supplier has kindly pointed out a feature of the group handle that I was not aware of.
    There is a screw on the handle that can be adjusted to regulate (direct) the flow as the shot is being poured, and this seems to have fixed the problem.

    Theres a screw on the handle of the portafilter that allows you to direct the stream to one spout or the other? Is it connected to a butterfly that site between the basket and the bottom of the portafilter or what? Got a pic of the portafilter with the basket removed?
