Synopsis: It is not uncommon that stones, wood chips and other foreign particles end up in a bag of coffee.

It is not uncommon that stones, wood chips and other foreign particles end up in a bag of coffee. This will cause any grinder to jam up (humming motor). The easiest way is to open the grinder to its coarse setting and see if the particles pass thru the burrs. Next step is to take the grinder apart. Pending on the model, this is easily done. Then vacuum out the grinder.

IMPORTANT: When adjusting a burr grinder to its finer settings, only do so slowly, while the grinder is running! Otherwise the beans get crushed between the burrs, causing the grinder to jam up.
You can then also try to use the Urnex Grindz cleaning tablets to clean the grinder.

useful info, grinder on my Saeco Intuita got stuck,
as it turned out a small stone (or toasted coffee bean pod?) had wedged itself down the hopper spiral.
Luckily got it out without further damage by gently turning spiral by hand in return direction.
Administrator Note:
Thank you for sharing. Yes, it is very common to get stones and wood chips inside coffee bags and they can jam up grinders. Sometimes using a vacuum might help removing foreign items from grinder burrs.

Since I use oily dark beans, the grinder gets clogged often if its not cleaned regularly. I use a small handful of beans at the coarse setting, grind away then adjust the grinder to my normal setting, let the first seconds of first coffee grind go the compost way with the ground cleaning beans. Voila !
