Hello, my friend, there are many reasons why beans can't be broken.

I don't know how long you have bought your machine. If it takes a long time, his blade will be dull. I suggest grinding it to see if you can break the beans.

Besides, the soaking time of beans also has a great relationship. Generally, 8-1 hours is the best.

Other aspects may also be the power of the machine, if you live.
