Quick Mill Arnos: Portafilter Too Tight

Troubleshoot portafilter not fitting in new Quick Mill Arnos.

Portafilter Is Too Tight on Brand New Machine

If you’re the owner of a new Quick Mill Arnos 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 into 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.
