The machine may be clogged when you grind fine coffee ground. Please check if the machine has power or not after plugging in power cord. If not, please contact us for maintenance. If yes, please turn on the machine and switch grind size to coarse setting to release the coffee beans.

Every coffee grinder has little bit deviation on ground size. We suggest user can start from grinding size #4.
