WASHING CYCLE
The washing cycle cleans the coffee groups and it must be carried out as follows: Place the blind filter
into the filter holder. Put a specific detergent for coffee
machines inside the blind filter (equivalent to a full dessert
spoon) and place the filter holder in the group to wash. Push
the continuous key (K5GRx) and the 1st dose key at the
same time. As long as the washing phase is in course, all the
LEDs corresponding to the pushed keys, blink and they will
only stop if any other key of the group is pushed (in this case, all the other LEDs light up and the washing
cycle stops). The washing cycle is composed of 5 cycles of 25 seconds each.
When the washing cycles are over, the machine automatically returns to the position ON.
It is possible to wash several groups at the same time.

ALARM SIGNALING
4.1
Boiler filling up Time-Out
Each time the maximum level probe (SLmax) doesn't detect water (uncovered probe), the filling up phase
(if EVCAR+PUMP are set in synchrony) starts, while the micro-controller activates an inner timer that
controls the time length of this phase.
If EVCAR+PUMP work continuously for a period of time superior to the one defined by TIME OUT,
(120, 180 or 240 seconds), the volumetric control is deactivated and the keyboard is "disconnected".
All the LEDs of the keyboards blink, in alarm.
Please turn OFF and ON again the machine to exit the alarm phase
