FAQs

How often should I clean the grinder?

It is recommended to clean the grinder every 1-2 weeks, depending on usage. More frequent cleaning may be necessary if using oily beans.

Can I use pre-ground coffee?

The Eureka Mignon Zero is designed for grinding whole beans. Using pre-ground coffee is not recommended.

How do I adjust the grind size?

Use the stepless micrometric regulation knob located on the side of the grinder. Turn the knob to the desired grind setting; finer for espresso and coarser for other brewing methods.

What kind of burrs does the grinder have?

The Eureka Mignon Zero uses 55-mm flat burrs.

What is the purpose of the ACE system?

The ACE system (Anti-Clump & Electrostaticity) minimizes clumping and static electricity in the ground coffee, resulting in a more consistent dose and less mess.

Is the grinder suitable for commercial use?

The Eureka Mignon Zero is designed for home use and small-scale professional settings, as it has a daily capacity of 1–1.5 kg.

How do I replace the burrs?

Remove the top burr carrier and unscrew the burrs. Install the new burrs and reassemble the grinder. The grind setting is kept unchanged after maintenance (whether cleaning or replacing burrs).

Troubleshooting

Grinder not turning on.

Check the power connection and ensure the grinder is plugged into a working outlet. Check the on/off switch.

Inconsistent grind size.

Check that the burrs are properly aligned and that the grind size adjustment is set correctly. Clean the burrs to remove any buildup.

Grinder is noisy.

Ensure the grinder is placed on a stable surface. Check for any objects that might be causing vibration. If noise persists, the burrs may be worn and need replacement.

Coffee grounds are clumping.

Ensure the ACE system is functioning properly. Experiment with different grind settings.
