When alarm COM Err appears, the display will show the number of the electronic board that
generated the communication error.

If, after a communication error, the machine is able to re-enable the communication between the
boards, the following message appears on the display:

* If the value of the parameter "Heat tim. enable" (HtE) is "Yes" (1), the machine stops when this alarm
appears. If the parameter value is "No" (0), the machine does not shut down when this alarm appears.
** The machine does not shut down if these alarms appear. Every 8 seconds a message indicating the
alarm number is shown on the display. A red LED blinks, but the machine continues to carry out the normal
operations.
*** This alarm causes machine stop in versions without prewash. In prewash versions the machine continues

E LACK OF DETERGENT AND RINSE AID WARNINGS
ALr
rnS
Out
ALr
dEt
Out
Lack of rinse aid
The lack of rinse aid warning is generated when a rinse cycle is in progress and the optical sensors
(emitter and receiver) installed in the dispenser detect the absence of the cartridge.
Lack of detergent
The lack of detergent warning is generated when a wash cycle is in progress and the conductivity
sensor installed in the tank detects that for 6 minutes (parameter dAd Detergent alarm delay) the
concentration of detergent in the tank is below the set point value, and more precisely when
Compensated conductivity < Detergent set point + Detergent set point offset. If the concentration of
detergent in the tank is below the set point, the low level warning (not visible to the user) is
immediately generated, but if after 6 minutes the concentration continues to remain low, the
message visible to the user is generated.
