Hi,
So I was going about my night, decided to pop on the ole Breville Dual Boiler. The Smart Grinder is busy at work for my double shot and then I hear this really bad sound and the grinding stops! I'm like…It's only a year old, shouldn't be playing up. Taking it apart I find a small coffee bean sized rock lodged in the burrs! I think the grinder is ok.

Be careful!
I've emailed them.
Thanks for the info. Would be more careful now
