My bodum cone coffee grinder motor runs but does not grind the coffee beans, seems like it is not turning, what could it be?

We just went through the same situation. We opened the top the Magnifica to get to the grinder and removed the four screws to seperate the grinding pieces. Inside we discovered two black fosilized beans/stones! We removed those, cleaned out all the bean dust and it is working like new! Took about an hour.

I had a similar problem, and solved it by turning the grinder by hand against resistance. Apparently the grinder wasn't really turning during the cycle and needed to be cleared. If your beans are "hopping" this may be a different problem.

Testimonial: "Grinder is turning but old bean oil is clogging it. Stirring beans on next brewing after drying the grinder was also customer services recommendation"

This fixes almost all the "beans will not feed or beans will not grind" problems caused by coffee bean dust packed in the burrs. Oily beans cause this problem more fequently.
a. Pour all the beans out the top.
b. Open the settings up all the way and see what else can be poured out. Use your shop vacuum to **** grounds out the spout and backward out the bean bin.
c. Pour in some instant rice and start grinding. Reduce the grind to a small setting like six and then open the settings all the way again. (The grinder will not start at a low setting with the rice in it. If you let it stop, open the settings to about 16 before trying to restart.)
d. Pour out the rice and vacuum out the ground rice.
e. Adjust the grinder to your favorite setting and try a coffee grind. Grind until most of the rice dust is expelled (any remaining trace of rice dust will not affect the flavor of the coffee).

Hi Sounds like you have a blockage in you grind passage. Try removing the brew group. Then inside on the roof of the machine where the brew unit was setting there is a drop chute where the coffee is dropped into the brew unit. From the left side of the drop chute pull down and back, and it will drop coffee. This will clear an opening that relieves pressure on the passage. There is a passage inside the drop chute area that goes to the grinder. Vacuum it out. It will be on the right side of the drop chute. Once that is cleared go to the bean hopper. There is a lever under the bean hopper. Push the lever back to the largest number. You can push the lever to a larger number any time, but it has to be grinding to pull to a smaller number. Now replace everything and make your coffee. Once you have made your coffee you can pull back to a number that was higher than the one you had it on, but only when the grinder is running.
