    Can feel grinds on the shower screen after a pour

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    After I pour a shot, before I backflush I can feel some grounds on my shower screen. Does this mean I am overdosing?

    i know that the grinds expand but dont know if Iím over dosing.


    Is it nornal for geounds to be on the shower screen? Not a lot, but enough to feel with finger tips.

    Im using a 18g basket and dosing with 18g.

    I cns try and dose with 16g and see if there is any difference?

    My breville didnt do it. But my musica does. Preinfusion isnt turned on on the musica, but that is possibly the difference

    Nothing to worry about, it's normal.

    "geounds to be on the shower screen": Normal within reason. Generally the oilier the roast, the higher the dose and the poorer the technique, the more buildup you will get. However zero buildup should never be a "main goal" - the taste of the coffee is far more important.

    You just described why I always do a quick postflush (under 5 seconds I expect) and wipe down (up?) of the grouphead between shots. Coffee grounds are like grinding paste - they will destroy seals and collars if left in situ.

    I also do a preflush, mainly to get the p/f and basket up to temperature. Needless to say, that will vary in timing according to p/f temperature - and why I still prefer naked brass p/f's (they heat up quicker than stainless).

    Enjoy your cuppa, keep your machine clean and all will be well.

    Completely normal so long as there's not clumps that have stuck to the group head.
