Maintenance
How to look after your Mignon Libra
A grind-by-weight grinder, such as the Eureka Mignon Libra, Atom W or Baratza Sette 270Wi and Forte, needs the same cleaning as other grinders, plus a clean fork and a scale that is calibrated when the weight drifts. Here is the schedule and the products we recommend.
Good to know about the Eureka Mignon Libra
Calibration is only needed if the scale loses accuracy. Hold down the two buttons specified in the manual for about 7 seconds, tare the portafilter and follow the steps with a known test weight.
The dosing button is active for 10 seconds after the portafilter has been inserted. If the display shows FH, remove the portafilter and insert it again.
Wash the bean hopper at least once a week and adjust the grind with the motor running. Eureka specifies checking and, if necessary, replacing the burrs after 300 kg of coffee.
