    grounds stay in group head on Boema

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi All
    A quick question- on my 1 group Boema I get grounds outside the showerscreen/ dispersion block after I remove the portafilter. By that I mean on the sides of the block (showerhead) and edges of the group seal. I didnt get this on the Bezzera even though it is the same or similar to the Boema. I also dont get it on Botticelli. I usually clean these by doing the p/f wobble (loose in the group head) or with a back flush, but it is every time I use it.
    Im wondering if the dispersion block is a little undersided especially since it has a perforated stainless steel shower screen unlike the usual wire screen one (maybe this is normal for Boema).
    Any thoughts?

    Sounds normal, especially if the group seal is halfway up the shower screen.

    Ah, the times when you should trust your own judgement. The shower head was about 5mm undersized. I compared it to an ordinary 58mm style one and the difference was amazing- also there was a difference between the shape- all the ones Ive fiddled with before had chamfered/ bevelled sides that fitted fairly neatly into the filter basket. I had not been able to check before because the thing had a seized screw- amazing what you can do by removing the grouphead and hitting the screw with an impact driver!
    All fixed and happy.
