La Cimbali M39 Class GT Utilisation Et Installation page 49

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) 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.
Filter-holders
1) Put a liter of cold water in a suitable container and add
detergent.
2) Soak the filter-holders in this solution for about 2 hours.
3) Remove the filters from the filter-holders and wash the
parts in the same detergent solution, using a small
sponge.
4) Flush thoroughly with cold water.
5) Reinstall the filters in the filter-holders, making sure that
filter-retainer spring seats properly.
Steam and hot water dispensing pipes
Using a clean sponge, wash with hot water removing any
organic residue present. Rinse carefully.
To clean the inside of the steam nozzle, follow these steps:
Turn the nozzle towards the cup tray and carefully activate
steam dispensing at least once.
Grille and Drip Basin
Remove the grille from the basin, extract the grille section and
complete the cleaning operation under running water.
ATTENTION
When the machine has not been used for
more than 8 hours, and in any case once a
day, the internal components must be washed
before use, in accordance to the following
instructions:
Supply Groups
Insert the filter carriers into the groups (without coffee) and
dispense from each group for one minute.
Block function
If the coffee wash circuit key is pressed (26), the previous
message will be integrated as shown:
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.
Discharge Basin
At the end of the working day, pour about a liter of hot water
into it to remove any discharge residues.
Bodywork
Use a soft cloth and cleaning products WITHOUT ammonia
or abrasives, removing any organic residue present in the
work area.
Note. Do not spray liquids into the panel slots.
Hot water
Dispense hot water repeatedly (using the relative
command) until at least 5 liters of water have been
dispensed.
Steam
Allow the steam to flow for approximately one minute,
using the appropriate commands.
