6.2 HEATING ELEMENT
The NEO technology manages tempera-
tures of the "infusion group and coffee boil-
er" system, to give a proper extraction water
temperature, in accord with what has been
set in the programming as MYCOFFEE tem-
perature.
When the heating element of the coffee
boiler needs to be powered ON, the control
unit actives it.
To know when it is activated, it is possible to
monitor LED placed on the control unit.
The LED is labelled "CH".
NOTE
For further information about the con-
trol unit, refer to Chapter 8.
6.2.1 CHECK AND REMOVAL
OF THE HEATING ELEMENT
To access the heating element, it is nec-
essary to remove the coffee boiler as
described in the previous paragraph.
To detect if the heating element is dam-
aged, it is possible to verify its value with a
tester.
Typical value is 90 ± 7 Ohm.
If the breaker of the electric panel in the bar
interrupts the power, the cause could be
the heating element in short circuit.
Use a tester to verify continuity of the heat-
ing element with the ground: continuity
would mean the heating element is dam-
aged.
If the power does not interrupt but the water
of the coffee boiler is cold, the cause could
be the heating element in open loop.
Use a tester to verify continuity of the heat-
ing element itself: continuity would mean
the heating element is fine.
