ERROR:
If the number remains 0, the display turns red, and the motor is run-
ning, the problem lies in the Hall sensors, or their wiring, or in the Control
Board/Power Board input (JP2). If the motor does not run, the problem
may lie in the chain (JP8), the coffee grinder wiring or the actual coffee
grinder.
Temperature control
The circled number expresses the boiler temperature in degrees centi-
grade.
ERROR:
If the HEATER indicator shows the word "SHORT", this means that the
NTC temperature sensor is in short circuit and the display turns from
green to red. In this case, check the wiring of the NTC or the Control
Board/Power Board (JP13).
ERROR:
If the HEATER indicator shows the word "OPEN", this means that the
NTC temperature sensor is disconnected, the display turns from green
to red.
In this case, check the continuity of the NTC wiring and check the con-
nection to the Control Board/Power Board (JP13).
Press the COFFEE button to activate the Boiler
The indicator changes from "OFF" to "ON" and shortly after the tempera-
ture indicator should start to increase, and any ammeter at the techni-
cian's disposal on the counter must display an absorption of approximate-
ly 8 Ampere with 230 volt.
ERROR:
If the temperature is not absorbed check the boiler resistor, relative wiring
and the connection to the Control Board/Power Board input (JP19), also
check the wiring on the NTC (JP13).
If the temperature goes above 125°C then the display turns yellow and
an alarm message appears on the display.
Above this temperature the boiler is always off, avoiding the risk of dan-
gerously high temperatures.
