Portafilter Is Too Tight on Brand New Machine
If you’re the owner of a new Profitec Pro 300 and the portafilter is tight inside the group head, this is nothing to worry about.
As long as water is not leaking around the portafilter from the group head, this is totally normal. Over time, the portafilter will wear in to a normal 6 o’clock position. It could take about a month or two. As long as it is making a good seal, then it is fine. In another year or so, the gasket will need to be replaced again, and may still be a little off center in the beginning.
