Mazzer Mini Timer Doser Espresso Coffee Grinder - Overview


Mazzer Mini Timer Doser Espresso Coffee Grinder

The best-built, commercial espresso grinder for home use and an exceptional choice for commercial use. The Mazzer Mini Timer version has a switch on the side so that the grinder will automatically stop grinding. Mazzer no longer produces a manual on/off switch version because they fear grinders may accidentally be left on all day. The built-in timer allows the unit to auto-shut off after the right amount of time. In other words, you can have the Mazzer Mini grind just the right amount of coffee based on time. However, if you keep the time the same and change the grind setting, the yield will be different.



  • Timer – Located on the right side of the grinder. Turning the dial all the way will start the grinding process and will stop after 1 minute. To manually stop the grinding process, turn the dial back counter clockwise. The timer acts as a safety feature to prevent users from walking away and overflowing the doser.

Grinding adjustment

  • Stepless – Infinite number of grind settings which allows you really fine tune your grind. Adjustment dial is located underneath the hopper. The entire dial is numbered so you can remember your current grind setting easier. Turn clockwise for a coarser grind and counterclockwise for a finer grind.
  • Adjustment lever – This lever screws into the adjustment dial and helps you easily change your grind settings. There are 5 positions where you can install this lever. Once you find your correct grind setting, you can move the lever to another position that won’t stick out the sides.

Grinding burrs

  • Flat burrs – Large size at 58 mm. The larger the size, the more of a grinding surface, resulting in faster production.
  • High rpm – Faster spinning rate at 1600 rpm. The higher the speed, the faster the production, which can increase efficiency and reduce wait times.
  • Easy access – Remove the bean hopper. Turn the grinding adjust to the coarser direction until the top assembly comes off. This will give you access to the burrs and the grinding chamber. You can remove the burrs with a Flathead or Philips head screwdriver.

Bean hopper

  • Low profile – The total height of the grinder without the hopper is a little under 12″. The bean hopper adds another 5″ bringing the total height to approximately 17″. The total capacity is approximately 1.3 pounds of whole coffee beans, a little over half the size of a standard kilo bag.
  • Set screw – Secures the hopper to the grinder. Serves as a reminder for users from quickly removing the hopper if it is full of beans.
  • Finger guard – Prevents users from “accidentally” putting their fingers in the grinding burrs.
  • Stopper – A door near the bottom of the hopper slides inward to close the opening. This allows you to remove the hopper with beans inside so you can easily change the beans. There will be some beans already passed in the burrs which will have to be ground out first before removing the hopper.


  • Adjustable dosing – Allows you to change the amount of ground coffee dispensed into your portafilter.
  • Finger guard – Located in dosing chamber.
  • Portafilter fork – Solid, chrome plated. Directs your portafilter right underneath the doser chute.
  • Built-in tamper – For those that want one. You can easily uninstall if you do not want to use.

ETL Certified

Effective July 17, 2006, all of our Mazzer Mini Timer grinders have an ETL certification. ETL certification insures that a manufacturer is utilizing quality components for product safety, and ongoing inspections and site visits by ETL insure that manufacturers do not deviate from those standards of product safety. Ultimately, this insures you that internal components are the same (no cost cutting) without the approval of ETL.

  1. Changing grind settings: As with all coffee grinders, it is very important to only change grind settings when the unit is powered ‘on’ and the burrs are in motion. If you do not do this, the burrs will ‘gunk’ up and require cleaning by you every time this occurs. Changing the grind settings when the burrs are not in motion will render the grinder to only produce very coarse grinds or no grinds at all. If this result occurs, this will be considered operator error for lack of following directions, and not be classified as a defective grinder.
  2. Finding coffee grinds in a new grinder: We have confirmed that the manufacturer tests EVERY grinder with coffee beans before it leaves their facility, but they are not always able to get every trace of coffee out of the grinders after testing. As a result, you may find coffee beans or grinds inside your grinder, or there may be grinds in the packaging when you unwrap it.
  3. Static issues: There are static issues with all grinders, even the highest quality models. We firmly believe that the static comes from the coffee beans. If you are having static problems with your coffee grinder, trying using a different blend of beans.
  4. Replacing burrs: NEVER use a flat head screwdriver and hammer to wedge under the burrs for removal. This could badly damage your grinder.
  5. Electrical cord: Please note that the electrical cord is placed between the packaging (foam or cardboard) and the underside body of the grinder. During shipping, it is normal for a bend or insignificant blemish / slice to damage the cord.

  1. Manual switch models: These models are no longer being produced by the factory.

Espresso Grinder Warning

  • CLEANING WARNING: We recommend using grinder cleaning agents. We do not recommend any removal of the burrs or burr carrier for cleaning as re-assembly can cause damage.
  • ELECTRICAL WARNING: To avoid electrical damage to this espresso grinder which is not considered a manufacturer's defect, please acquire and install a single-outlet surge suppressor rated at 1080 joules or higher. The lack of the recommended surge suppressor, the espresso grinder can be damaged at the power switch, the capacitor, the motor, or the wiring.

      We do sell Mazzer OEM parts, but we do not get involved with conversions nor do we provide any answers nor guarantees of fitment with conversions. You may find others online who have performed these conversions.

      Sorry, this will require a bit of research as Mazzer does change their height sizes quite often, and they do change their bean hoppers less often without any notification to us.
