The Cup-Warmer; List Of Malfunctions; Operating Safety Devices - Rancilio CLASSE 10 Serie Emploi Et Entretien

9.3. Displaying
9.3.1. Warming Up Phase
During the warming up phase, the following message
is displayed:
"Machine "not ready" "
Until the set pressure is reached.
The following messages are also displayed, con-
cerning:
"Please make the regenerate softener", if the
function is enabled and the set values have been
reached (this message will be then repeated every
hour until it is reset)
"Please make the service time", if the function is
enabled and the set values have been reached (this
message will be then repeated every hour until it is
reset)
9.3.2. Operating Mode
Once the temperature/pressure has been reached,
current date/time or pressure is displayed (for 20
sec.) alternatively to two logo (10 sec. each, to be
personalized).
During dispensing, the following is displayed:
If one of the two time control functions is activated,
instead of the coffee symbol the following is shown
in sequence:
- The GrX (X= n. activated group) flashing throu-
ghout the dispensing period
- The dispensing time in the row under GrX for 10
seconds at the end of dispensing

9.4. Operating Safety Devices

When the coffee maker is switched ON, it checks
whether there is enough water in the boiler.
9.4.1 If the water level is inadequate, the machine
tops up the level automatically. If this does not
take place within a set period, the boiler filling
operation is discontinued and a warning message
is displayed: "Low water level".
9.4.2 If the water presence check result is positive,
the boiler heating resistances are enabled.
If the set pressure is not reached within a specific
time, the power supply to the heating resistances
is cut off and a warning message is shown on the
display: "Low pressure".
9.4.3. If the safety device for slow dispensing in-
tervenes, the LED of the dispensing button must
flash until the end of dispensing.
The boiler safety devices can be reset by switching
the machine OFF and then back ON again

By pressing the relative button, the display shows
the following:
Depending on the darkened segments it indicates the
selected power status of the cup-warmer resistances
(min – med – max – off).
The passage from one level to the next is explained
in the relative chapter (7.1 pag.17).
9.6. Dose Programming Phases
During the programming phase for self-learning,
the display shows the following flashing message:
'Programming doses...".

9.7. List of malfunctions

G00 = CPU check
G01 = Water missing
G02 = Pressure low
G03 = Boiler probe short-circuited
G04 = Boiler probe cut off
G05 = Connection IDS
G06 = No resin reconditioning
G07 = No maintenance
G08 = Coffee washing cut off

10. MAINTENANCE
Maintenance operations have to be carried
out when the machine is off and cold and
the plug is disconnected. Some particular
operations have to be effected when the
machine is operating.
Do not clean the machine by using metal or
abrasive devices, such as steel wool, metal
brushes, needles, etc. or general detergents
(alcohol, solvents, etc.)
When necessary, use special detergents for
coffee machines that can be bought in spe-
cialized service centres.
10.1. Daily (Fig.10)
Use a clean cloth or sponge that does not leave hairs
or fluff (preferably cotton or linen).
● Carefully clean the outside surface, following the
grain of the satin finish on the parts in stainless
steel.
● Clean the steam and hot water spouts and check
that the nozzles are not encrusted (if they become
encrusted, be careful not to deform or damage
them).
