Frequently Asked Questions - MR454 Maestro

How do I clean the coffee grinder?

Can I grind other ingredients like nuts or sugar?

What is the maximum amount of coffee beans I can grind at once?

The maximum capacity is 50 grams per load. Do not exceed this amount to avoid overloading the motor.

For coarse ground, grind for 10 seconds. For medium ground, 20-30 seconds. For fine ground, 40-60 seconds. Adjust time to achieve your desired texture.

The safety interlock prevents the grinder from operating if the lid is not properly closed. This protects users from accidental contact with the sharp rotating blades.
