in an automatic way, by running multiple
cleaning cycles.
• This espresso machine has a group rinsing
function (rinsing jets) integrated in the
electronics.
• The rinsing procedure is provided to give

MOST DETERGENTS CAUSE FOAMING DURING THE CLEANING PROCESS. THIS FOAM COLLECTS
AT THE DRAIN BOX AND CAN PROHIBIT WASTE WATER FROM DRAINING PROPERLY.
RINSE ONLY ONE GROUP AT A TIME.
RINSING MULTIPLE GROUPS SIMULTANEOUSLY COULD CAUSE THE DRAIN BOX TO OVERFLOW.
