to use the correct filter-holder with relevant filter and
be sure to use freshly ground coffee.
Then carry out point 6 and repeat point 7 to check
all changed doses.
If all group head are to be programmed with the same
doses, the programming of coffee doses is finished.
If the dosage of another group head is to be changed
