DAILY MAINTENANCE
Empty and clean the coffee filters.
Place the blind filter (except for the lever model) in a filter holder together with a tablet of special detergent for
coffee machines.
Insert the filter holder in the coffee dispenser head and operate it for about 40 seconds. Repeat this operation
several times until the water issued from the head is clean.
Clean the steam pipe with a damp cloth and purge it several times.
Allow the hot water to flow and clean the drainage tray of all coffee remains that are deposited on the bottom to
prevent fermentation that could originate unpleasant odours.
The outside of the machine should be cleaned with a cloth or absorbent cloth moistened in clean water.
NEVER use detergents or abrasive products.
NOTE:
The filter holders should be located in the groups to maintain them at a constant temperature

OBSERVATIONS
If the water has particles in
suspension or is too hard a calcium
filter must be installed.
Check the pressure on the gauge.
To know whether the flashing is due
to the coffee, because of lack of
water, or the counter, remove the
filter holder and press any button

continues and water is dispensed,
it must be due to the counter.
