Motor revs but grinder does not engage.

Hi,
I am what you would call an expert when it comes to Baratza repairs.
The problem you are describing is not an unusual one. It sounds like the main drive gear has been stripped due to something foreign (likely a stone) sneaking into your grinder with the beans. It would have jammed the burrs, and because of the powerful torque from the motor, the drive gear has been stripped so it will no longer (or rarely) engage the burrs.

To solve this problem you will need to contact COAG Ltd (if you live in Canada) or Baratza if you are from the US. If you machine is still under warranty (less than a year old) this repair will be free of charge and you shouldn't be parted from your grinder for long.

I hope this helps anyone who stumbles upon this and finds themselves with the same problem.
Kind Regards

1. for PORFLANO : your grinder's axis probably have security spring for avoiding further destruction you should open it and pay attention to spring, change it if it is broken.
2. JAMESEIME& BARON check the axis before closing the grinder motor, are thay attached good to lower burr. be sure they are.
