Note: If no wash cycle messages appear and the machine
is used frequently, a wash cycle can be performed at any
time, using the methods described earlier:
- milk circuit washing cycle: pressing the (28) key;
- coffee circuit washing cycle: pressing the (26) key;
N.B. Once the wash cycle is underway, it CANNOT be
stopped, even if the machine is switched off.
If there is a power failure, when power is returned the mes-
sage "EXECUTE WaSHING" will be displayed. Complete
the cleaning operations as described previously.
When the machine is blocked, a warning message appears
on the display: if the key corresponding to the requested
wash cycle is pressed (key 26 or 28) and the instructions on
the display are followed, the wash cycle is performed and the
machine is no longer blocked.
For example, if there is a "coffee block", the following message
appears on the display:
GROUP 1 LOCKED
EXECUTE WASHING
The number of the "blocked group" blinks on the display and
depends upon the number of machine groups.
20. Cleaning and maintenance
Block function

The wash cycles performed without request by the machine
can be interrupted by switching off and switching back
on the machine.
The simultaneous washing mode lasts 7 minutes. The single
washing mode lasts 7 minutes for each dispensing group.
Programmed wash cycles that are not effected will be memo-
rized by the machine.
If the coffee wash circuit key is pressed (26), the previous
message will be integrated as shown:
GROUP 1 LOCKED
EXECUTE WASHING
INSERT FILTER HOLDER
When the "INSERT FILTER HOLDER - GROUP 1" message
appears, the block message for Group 1 disappears. The
block messages for groups still to be washed appear in al-
ternation.
At this point, please follow the steps described in the "** COFFEE
WASH CIRCUIT'" paragraph to perform the washing cycle.
