Many users of the Breville BCG600SIL (and BCG400) Dose Control Grinder experience jamming / clogging issues. After bogging down either it just stops and flashes the button light, or makes a clacking sort of sound and little coffee comes out. This is usually either a worn out impeller or stripped drive gear. The main symptom of a worn impeller ...
