- MAINTENANCE
Maintenance operations have to
be carried out when the machine
is off and cold. Some particular
operations have to be effected
when the machine is operating.
Do not clean the machine by
using metal or abrasive devices, such as
steel wool, metal brushes, needles, etc. or
general detergents (alcohol, solvents, etc.)
When necessary, use special detergents
for coffee machines that can be bought in
specialized service centers.
Keeping your machine clean will prolong
its life and produce much better espresso
beverages.
