Remember, as to get the best performance from the machine, descale and cleaning are to be observed.
Disconnect the machine from the main supply prior to cleaning the machine. All the body exterior can be
cleaned with a damp cloth. Do not use abrasive or dissolvent products.

18.1. Cleaning of group

•
Unlock & remove the porta filter from the group head.
•
Place the blind filter membrane on the filter basket.
•
Insert a sachet of detergent into the porta filter. You must use specific detergents for this kind of
cleaning, suitable for the cleaning of the group of espresso machines.
•
Lock the porta filter into the group head.
•
If you have a Pulser machine (no keypad) press the brew switch for 10 seconds, then release for 3
seconds; and then repeat again this action for at least five times more.
•
If the machine is of the type Control, (it has keypad), activate the auto-cleaning cycle as follows:
Switch off the machine, then keep pressed the button "2 short coffees" and turn on the machine. Now you
can release the button; the auto-cleaning will automatically repeat a cleaning cycle.
Important: Once finished the cleaning process, remove the porta filter and run water through the group again
to rinse out all remains. Repeat the cleaning process without detergent once more for a perfect result.
"DO NOT MANIPULATE THE PORTA FILTER DURING THE AUTO - CLEANING PROCESS".
•
Cleaning the groups everyday with the filter membrane but without detergent is recommended.
•
Cleaning the groups with the filter membrane and detergent is recommended once a week.

18.2. Cleaning of gasket & shower
When attaching the porta-filter filled with grinded coffee into the brewing group, left overs accumulate in the
closing surface. These remains if excessive can prevent a good closing between the porta-filter an the brewing
group. Moreover, these remains can even block the output of water through the group.
The solution for this is cleaning:
•
Place on the filter basket the blind membrane filter, without detergent.
•
Place the porta-filter in the brewing group, without attempting to close it. IT MUST BE LOOSE.
•
Connect a continuous espresso (switching or selecting).
•
Make an opening - closing movement of the porta in place, without closing it. Water will flow around
the porta filter, flowing through the closing surface, cleaning it. Be very careful, as this water is very hot,
and can cause burns.

18.3. Shower cleaning

With a scouring pad, whip the shower's area
both interior, and exteriorly.
