Grinder display
shows Hi or Lo
The grinder is providing
feedback that you are
wanting to use a grind
size that is outside the
recommended average
range for Espresso.
Experiment with optimising your
brewing within the standard
recommended grind size range.
If your preference is for a very fine or
coarse grind, then it is perfectly OK to
use the grinder whilst it is displaying
Hi or Lo.
