I set up my two different cups of coffee, one on the finest grind setting the other on the second coursest setting.When I make a coffee shouldn't the grind setting knob move as they're both different?

I have a Zass and sometimes have a problem with it self adjusting, but when I do need to adjust it, I find that I have give it a good tap on the top to make sure it adjusts. So, just turn the knob counter clockwise as far as it will go, then give it a good knock on the top and bottom and try again. My mill offers the full grinding range, from a fine powder to large chunks.

your grinding chamber is blocked, the same happened to me, did it struggle to grind before? try taking the black shoot out the top with the 2 screws( were you would put pre ground coffee in) take the brew unit out(along with the waste water and bean tray), and reach up to where there is a little spring, the spring controls a little door, if you open the door manually and clean out the shoot to the grinder( make sure the machine is unplugged for this), i used the end of a tea spoon and a little hoover. it should work after this

The best solution I have was referred to me by a mate of mine who services commercial coffee machines.

Step 1. Remove the base of the grinder... this is actually the hardest aspect of this task... as there is one tamper-proofing screw... if you can't get the correct star-hex screw driver I recommend drilling the screw out.
Step 2. Once the base is off you will see the main shaft of the grinders motor. The shaft has a star washer set in behind hew nut, the end of the shaft has a slot cut into for a flat bladed screwdriver. Hold the nut with a pair of pliers & you can adjust the shaft positioning (& hence the burr attached to the motor) by about 3mm....

You will need to experiment to find the correct level of fineness as you require.

If you need further information send me an e-mail as I'd be happy to forward more detailed instructions.

Good Luck.

Cheers.......

Hi
Your grinder adjustment ring inside has its tabs broken. Contact Baratza at 877-701-2021 and they should be able to help get a new one.

I have the same problem. Not a solution, but you can still take the ground beans and brew coffee, using the pre-ground compartment.
