Sensor malfunction
Boiler sensors
For each boiler sensor, the corresponding area in the display, as well as the 3-digit display, will show
O.C. (open circuit, infinite resistance) or C.C. (closed circuit, electric short) if there is a sensor
malfunction. When a sensor malfunction is shown for a boiler, the heating of that boiler is dis-engaged.
The machine will remain functional on the other boilers.
Even though the coffee boilers will remain operational when there is a steam boiler sensor error,
overall functionality of the machine will be low. When the display shows a boiler-sensor malfunction,
have the machine repaired as soon as possible (probably the sensor has to be replaced).

temperature sensor
Distribution block sensor
As the sensor in the distribution block has no designated area on the control panel, a sensor error is
indicated by a red centre line in all groups. There is no distinction between open or closed circuit. With
a malfunctioning sensor, the cool-valve will not open but the machine will remain functional. A non-
functional cool valve may lead to overheating of the groups. Have the machine repaired as soon as
possible.

Cup heater sensor
There is no indication when the sensor of the cup heater malfunctions. The only way to detect that the
sensor circuit is not operating will be very slow heat-up of the cup-heater after the machine is turned to
“operational” (from either OFF or ECO).
Start automatic back-flush program
Prepare blind filters with a little cleaning powder and lock-in. In the menu window, touch the button
“CLEAN PROGRAM”. Then pull all levers into locking position. You must make sure to remove all
cleaning powder from the group. To do so,
run the program a second time without cleaning powder
.
