Operating Safety Devices; The Cup-Warmer; List Of Malfunctions; List Of Warning - Rancilio CLASSE 10 USB Use And Maintenance

If one of the two time/doses control functions are
activated, the coffee symbol space will instead
display:
otherwise:
"Brewing time "
For energy saving purposes, the display will reduce
its luminosity after one hour of continuous inactivity
without dispensing anything. After two hours of con-
tinuous inactivity without dispensing anything, it will
switch itself off altogether.

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:
"G01 Water missing"
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:
"G02 Boiler Pressure low"
9.4.3. If the safety device for slow dispensing interve-
nes, 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

9.5 .The Cup-Warmer

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).
passing from one level to the next is performed by
pressing on the cup-warmer key.

9.6. List of malfunctions

The system electronics are capable of diagnosing
the following failures by displaying the relative error
codes on screen:
Because they are serious, these errors will stop and
block machine operations.

9.7 List of
The system electronics are capable of diagnosing the
following failures by displaying the relative error code
on screen (which will come flashing on alternatively
to the customisation logos).
Because they are not serious, these errors will allow
the machine to keep running.
We nevertheless recommend that you contact the
Technical Service Department in order to settle the
problem as quickly as possible.
