The machine is adjusting the co ee
grinder for a new kind of co ee
beans or pre-ground co ee.
The machine automatically adjusts
itself after brewing several cups of
co ee in order to optimise extraction in
relation to the compactness of ground
co ee.
It may be necessary to brew 2 or 3
products to fully adjust the co ee
grinder.
This is not a machine malfunction.
The co ee grounds pro-
duced by the machine are

If the residues are too humid, set a
coarser grind.
If the residues are too dry, set a  ner
grind.
