The function intended to control grinding wheels will dis-

the grinding time stored when grinding wheels were new
by over 50%.
After having replaced the grinding wheels and reassem-
bled the grinding wheel ring nut, use the function “New

have stored and to store the new average initial grinding
time you have measured during the rst selections.
After having replaced the grinding wheels or the grinder,
use the function “Grinding wheel test” before pouring
coee.
- If you confirm the test, grinding wheels come close to
each other to touch;
- the machine will stop, waiting for confirmation;
- if you confirm once again, grinding wheels depart and
rotate the grinding wheel ring nut by some turns;
- if you pour coffee and dispense some selections of
reference, grinding will automatically become stable.
