filter-holders
Pour a teaspoon of a suitable detergent
powder on each of the blind filters and
attach the filter-holders to the groups.
Using the right-hand button panel, press
at the same time button T1 and T5 to
activate the automatic cleaning cycle.
The buttons T2 ,T3, T4 will light up.
After the 10th cleaning cycle on the right-

process in the left-hand group.
The cleaning cycle will stop automatically
or by pressing the T3 button.

then undertake a few dispensing
operations using water only. Then
prepare a coffee in order to eliminate any
detergent residue.
Machine maintenance
Periodically check the following items:
Check the pump pressure gauge which
should indicate a value between 8 and 9
bar. In case of malfunction, request the
assistance of technical personnel.
Check the pressure gauge, making sure
that the boiler pressure is 0.8 -1.2 bar.
Check the conditions of the filters for any
damage along the edges and see if there
are any coffee grounds in the cup. If
necessary replace the filters.
