What diameter is the portafilter for the 900?
I bought a shelf model from DJ and i think it had the wrong portafilter in it. The 58mm baskets (all 4 of them) sit loosely in the portafilter, i cam actually jiggle them. The portafilter fits the group head (seemingly) well so I'm wondering if the portafilter is from another breville machine. Is there another machine in their range that is larger than 58mm?
