* 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
to work.

(compact
machines)
Communication problems between
machine electronic boards. - The bus connection cables are not correctly connected to all the boards.
- One or more boards don’t work properly.
- The “Appl. type” parameter (APt) is not correctly set.
- Connector X6 is not correctly inserted in the MEC boards.
When alarm COM Err appears, the display will show the number of the electronic board that
generated the communication error.
2: wash + rinse
3: prewash
If, after a communication error, the machine is able to re-enable the communication between the
boards, the following message appears on the display:
