Our dual-wall filter basket for the Breville Barista Express appears to be clogged. The video here is long but shows pulling a shot of water through the single-wall basket (fine) and then the dual-wall basket. We've been using the dual-wall basket…

DeLonghi 3420 jams

I have had a DeLonghi 3420 for over a year and overall am very happy with it. A primary requirement was that it takes up little counter space. We buy pre ground coffee (I know, sacrilege). Even thought I strip and clean the coffee basket every time…

Is there a simple way to see the distribution of particle sizes that my grinder produces?
