When the button LED (6) flashes (rapid flashing),
the machine requires a washing cycle for the cor-
responding unit.
To wash the unit, proceed as follows:
• position a large pitcher under the spout;
• lift and lower the lever of the unit;
• press and hold button (6) for 5 seconds, the cor-
responding LED goes off;
• check that the unit lever is closed, then press
button (6) again within 10 seconds to start the
process, the corresponding LED flashes;
• after dispensing 5 times, the first washing stage
will end, the LED of button (6) keeps flashing;
• insert the suction tube in a 0.5 liters of clean water
and press button (6) again;
• press button (6) again;
• wait for the performing of the rinse indicated by
the flashing of button (6) LED.
If the procedure is interrupted by turning off
the machine, the warning will reappear at the next
restart.
The washing request does not block the normal
use of the machine, which can continue to dispense
coffee drinks. However, we recommends running
the washing cycle whenever the warning appears.

During washing, never open the unit lever.

At the end of the washing procedure, the counters
will be reset and the warning will disappear.

Thermoblock descaling

14.1

Procedure

Af ter the
passage of 900
liters of water
(for both dis-
pensers), the
machine will
signal the need to carry out the descaling cycle through
the flashing LEDs of buttons (3) and (6) on both panels.
For the descaling cycle, perform the following steps:
• verify that there are no pods in the units;
• turn off the machine with the switch;
• place a large pitcher under all spouts and make sure
the levers of all the units are closed;
• remove the filter and fill the tank with a solution of
125 ml of "Puly Descaler" and 550 ml of water at room
temperature;
• replace the tank correctly in place;
• turn on the machine while holding down button (3)
on the right hand panel, until the LEDs of buttons (3)
and (6) go off;
• press button (3) again within 10 seconds to start the
procedure, the LEDs of buttons (3) and (6) of both
panels flash slowly;
• the machine performs 5 deliveries with a break of 15
seconds between each other;
• the machine pauses for five minutes, to allow the de-
scaling agent to work;
• after this first phase, the LEDs of buttons (3) and (6)
flash quickly;
• remove and wash the tank with warm water, place the
filter back inside it, and then fill it with clean cold water
and put it back in place;
• press button (3) on the right hand panel to start the
rinse;
• wait for the rinse to be completed (additional dispens-
ing), the LEDs of buttons (3) and (6) on both panels

The descaling request does not block the normal use
of the machine, which can continue to dispense coffee
drinks. However, we recommends running the descaling
cycle whenever the warning appears.
