Frequently Asked Questions - Mini Electronic Type B Mazzer

How do I adjust the grind size on the Mazzer Mini Electronic Type B?

Turn the adjustment disk under the hopper clockwise for a finer grind or anticlockwise for a coarser grind. Always adjust with the motor running and ideally with no coffee between the blades. After changing, grind a few doses to clear the duct before checking fineness.

How do I set the single or double dose amount?

Use the two trimmers located above the filter holder. The left trimmer adjusts the single dose (one cup), the right trimmer adjusts the double dose (two cups). Turning clockwise increases the dose, anticlockwise decreases it. A 180° turn changes the dose by approximately 1 gram.

How can I manually grind without using the automatic dose?

Press and hold the central push button (with both cup lights blinking) to activate continuous grinding. Release the button to stop. This is useful for adjusting the grind or for non-standard doses.

What does the thermal overload protection do and how do I reset it?

If the motor overheats due to overcurrent or jamming, the thermal overload protection cuts power. Turn off the switch, unplug the appliance, and allow it to cool. Then contact skilled personnel to inspect and repair the cause. Do not attempt to reset it yourself.

How often should I clean the grinder?

Clean the hopper periodically with neutral soap and water, and the grinding system with a dry brush. For thorough cleaning, skilled personnel should disassemble the doser and clean the outlet. Lubricate the grinding adjustment threads with food-safe grease after each deep cleaning.

Can I use this grinder for home use?

No, this grinder is designed for professional use only by skilled personnel. It is not intended for household use.

What should I do if the grinding blades jam?

Turn off the appliance immediately and unplug it. Do not attempt to free the blades while the machine is connected. Contact skilled technical personnel to inspect and repair the grinder.

How do I replace the grinding blades?

Blade replacement should only be done by skilled technical personnel. The upper blade holder is accessed by removing the hopper and adjustment disk. After replacing blades, grind a few doses and discard them before normal use.

Why is the coffee coming out too fast or too slow from my espresso machine?

If coffee flows too quickly, the grind is too coarse; adjust to a finer setting. If too slowly, the grind is too fine; adjust to a coarser setting. Also check dose weight, tamping, and espresso machine settings.

How do I clean the doser (grinder-doser version)?

Discharge all ground coffee, then use a dry brush to clean the star unit and pull the lever to expel debris. For deep cleaning, skilled personnel should remove the coffee outlet guard, unscrew the dose adjustment knob, and clean the bottom of the doser, especially the sharp edges and outlet.

SWITCHING THE APPLIANCE ON AND OFF

Grinder-Dosers with manual switch and Coffee Grinders

The on-off switch is used to turn the appliance both on and off.

To switch on: set the switch to I.

To switch off: set the switch to O.

Grinder-Dosers with time switch

In order to switch the appliance on, turn the timer knob clockwise.

The appliance switches off automatically. In order to switch it off manually, turn the knob anticlockwise all the way.

Automatic Grinder-Dosers

In order to power up the appliance, turn the on-off switch knob to I. In order to switch the appliance on manually, the switch knob must be turned all the way (to START).

The appliance starts automatically every 12 portions of coffee (every 6 portions in the model MINI/LUX and in the versions with shorter doser group). It switches off automatically when the doser is filled with ground coffee.

In order to switch off the appliance manually, set the on-off switch knob to O.

Electronic Grinder-Dosers

In order to power up the appliance, set the on-off knob to I. The display located on the lid of the push button panel will show a counter with the incremental number of doses ground by the appliance.

After having placed the filter holder on the filter holder fork, push:

- the push button on the left (indicating one cup) to grind and dispense a single dose;

- the push button on the right (indicating two cups) to grind and dispense a double dose.

The counter adds one for each single dose (one cup sign) and adds two for each double dose (two cup sign).

One can manually activate the appliance keeping pushed the push button for manual grinding (indicating a speaker icon) located in the centre of push-panel. Hold down the push button for manual grinding and the grinder will grind until you lift the finger. By using the push button for manual grinding no dose is added in the counter.

We suggest using the push button for manual grinding to adjust the grinding of the appliance. To switch off the appliance, turn the knob of the switch to O.

Mini mod. B Electronic Grinder-Doser

To power up the appliance, set the on-off knob to I.

After placing the filter holder on the filter holder fork, push the central button as follows:

• Push once to dose a single dose (the light indicating one cup turns on);
• Push twice (with a waiting interval of 1 second between pushes) to dose a double dose (the light indicating two cups turns on).

You can manually activate the appliance by keeping the central button pressed (both lights blink simultaneously); releasing the central button will stop the grinding. This central button is meant to facilitate the adjustment of the coarseness of the grind of the appliance.

To switch off the appliance manually, set the on-off switch knob to O.

ADJUSTING GRINDING

To achieve finer or coarser grinding, adjust the adjustment disk located under the hopper using the relevant handle. To increase the coarseness of the ground coffee, rotate the disk clockwise; to decrease, turn the disk anticlockwise.

The disk remains in the chosen position without having to be locked in place. The adjustment must be performed

with the motor on, and preferably without any coffee between the grinding blades. Grind small amounts of coffee to determine the optimal degree of fineness.

In the Electronic Grinder-Doser version, before checking the fineness of the ground coffee, grind some doses of coffee to fill the duct between the grinding area and the outlet. This operation must be done whenever the grinding setting has been changed to empty the duct of the previous ground coffee. Changing the grinding setting might vary the weight of the doses. Therefore, adjust the doses only after the grinding setting.

In the Grinder-Doser and Electronic Grinder-Doser versions, if the coffee comes out of the espresso coffee machine very quickly, it means the coffee is ground too coarse. Conversely, if it comes out too slowly, it means the coffee is ground too fine. Nonetheless, bear in mind that there are many conditions liable to influence the correct supply, such as the weight of the portions, the compacting, the espresso machine settings, and the cleaning of the filters.

COFFEE DOSE ADJUSTMENT

In order to adjust the size of the portion dispensed, the small knob located in the centre of the ground coffee storage container must be turned while holding still the star shaped dosing unit. By turning the small knob clockwise, the portion is reduced. Turning it anticlockwise results in an increase.

In order to collect the portions of ground coffee dispensed, insert the coffee machine's filter holder all the way onto the fork-shaped support under the ground coffee outlet. In order to release a portion of ground coffee, the doser lever must be pulled all the way and allowed to return on its own. Pull twice in a row for a double portion.

In manual coffee Grinder-Dosers and those with time switches, in order to assure the portions are regular, check every now and again to make sure the amount of coffee ground to be found in the doser is sufficient to cover the feeding star unit.

To centre the coffee drop into the filter holder, it is possible to carry out a sideways adjustment of the support fork located under the dispenser, by slightly loosening the fixing screws and then tightening them again after having moved the fork into the new position.

In order to adjust the size of the portion dispensed, use the push button controls located on the lid of the funnel. After having set the optimal degree of fineness, check the weight of the dose with a digital precision scale.

In order to adjust the dose press the push button "MENU" for 3 seconds; the display will blink.

Select the dose you wish to adjust : either the single dose (indicating one cup) or the double dose (indicating two cups). The display will show the grinding time (in seconds) of the selected dose. By pressing the push buttons "+" and "-" the grinding time can be increased or decreased and consequently the selected dose can be increased or decreased.

Approximately, a change of 0.10 seconds is equivalent to a change of dose of 0.15 grams (0.005 ounces).

To set the desired amount of grinding time press the push button "MENU" for 3 seconds. A blinking of the display will confirm the data have been saved and the exit from the adjusting program.

Use a digital precision scale to check again the weight of the dose and, if necessary, repeat above mentioned operation.

WHEN YOU ARE INSIDE THE ADJUSTING PROGRAM IT IS NOT POSSIBLE TO OPERATE THE APPLIANCE.

IF THE APPLIANCE GETS SWITCHED OFF (SWITCH IN THE POSITION O) BEFORE EXITING FROM THE ADJUSTING PROGRAM THE CHANGES ARE NOT SAVED.

In order to collect the portions of ground coffee, insert the filter holder all the way onto the fork-shaped support under the ground coffee outlet.

Mini mod. B Electronic Grinder-Doser

In order to adjust the size of the portion dispensed, one has to regulate the trimmer setting, positioned above the filterholder.

The trimmer on the left regulates the single dose (one cup).

The trimmer on the right regulates the double dose (two cup).

By turning the trimmer setting clockwise, the portion is increased. Turning it anticlockwise results in a reduction of the portion.

A rotation of 180 degrees (half a turn) of the trimmer results in a variation of about one gram of ground coffee dispensed.

In order to collect the portions of ground coffee dispensed, insert the coffee machine's filter holder all the way onto the fork-shaped support under the ground coffee outlet.

PRESSING (Grinder-Dosers)

STATIC PRESSING DEVICE: place the filter holder against the underside of the pressing device and push upwards.

SPRING PRESSING DEVICE: place the compacting disk against the upper face of the filter holder inserted in the fork-shaped support and press down on the spring pressing device knob.

• Do not leave the appliances turned ON without coffee in the hopper.
• In the Grinder-Doser version, avoid pulling the dosing lever partially, always pull it all the way.
• In the Coffee Grinder version it is essential that nothing hinders the flow of ground coffee from the outlet in any way in order to prevent the risk of the appliance stopping.

Consequently, avoid using coffee bags which are too small COFFEE OUTLET

with respect to the amount of coffee to be ground. At the end of each grinding cycle, shake the handle of the spout for a complete outlet of the coffee.

• Do not insert foreign objects when filling the hopper with coffee beans. Handle with clean hands.
• After any hopper filling and in normal use of the appliance, the hopper lid must be positioned correctly.

- FIRST INSTALLATION

For the correct use of the grinding blades, at the first installation or whenever the grinding blades have been replaced, grind some doses of coffee. Do not use those first doses. In the Electronic Grinder-Doser version, for the appliance to function at its best, on its first installation and every time the hopper is cleaned, after having ground a few coffee doses, clean the inner surface of the funnel with a dry brush.

E.g.: a data on the label 35s ON / 45s OFF points out an allowed duty cycle of 35 seconds switched on and 45 seconds switched off.

APPLIANCES WITH THREE-PHASE MOTORS ARE ALLOWED FOR CONTINUOUS WORKING.

In order to achieve good grinding, it is nonetheless recommended to operate the appliance at intervals, allowing it to operate for no more than 10-15 minutes at a time.

10) SAFETY DEVICES

THERMAL OVERLOAD PROTECTION

The appliance's motor is protected against overheating resulting from overcurrents by a thermal overload protection which, when tripped, cuts off the power supply to the motor. Should the protection trip as a result of anomalous operation, such as the grinding blades jamming, the appliance must be turned off using the on-off switch, UNPLUGGED FROM THE MAINS, AND SKILLED TECHNICAL PERSONNEL CONTACTED. NEVER PERFORM ANY WORK ON THE APPLIANCE WHILE IT IS ATTACHED TO THE MAINS, TO AVOID THE RISK THAT MOTOR TURNS ON SUDDENLY. If the appliance overheats as a result of the motor stopping, allow the appliance to cool down before performing any repair work.

SAFETY SCREWS

The hopper must always be attached to the upper grinding blade holder using the relevant screw, which must be tightened securely.

In order to prevent the adjustment disk from being removed - which would make the rotating parts accessible - there is a safety screw on the actual disk: said screw must be positioned in whichever of the two holes on the disk enables the wider and most suitable range of grinding adjustment, and must not be removed under any circumstances.

The coffee outlet guard must always be fixed to the doser (Grinder-Dosers), or to the funnel (Electronic Grinder-Dosers), using the relevant screws, which must never be removed by the user. THE REMOVAL OF THE COFFEE OUTLET GUARD CAN BE DONE BY SKILLED TECHNICAL PERSONNEL ONLY AFTER DISCONNECTING THE APPLIANCE FROM THE POWER SUPPLY BY UNPLUGGING.

Before reconnecting the appliance to the power supply, fix the safety device to the doser, or to the funnel, by relevant screws.
