13.3 ALARMS THAT DON’T STOP THE DISHWASHER FOR MODELS WITH
INCORPORATED CONTINUOUS WATER SOFTENER
WARNING:
Alarms marked with the Θ symbol from Serial Number 821 have become alarms
which do not lock the machine.
To facilitate the finding of faults signalled by alarm , another parameter providing a more detailed indication of the
possible cause of malfunction has been introduced in the family (see table below).
To reset error  it is necessary to disconnect and reconnect the main power supply to the machine by means
of the main switch on the external power board.
If alarm  or  appears, the machine indicates it on the display at regular intervals and auto-config-
ures itself in the same way as a machine without water softener. Resin regeneration cycles are not per-
formed and the column used for filling is always the same (column B).
Alarm
 is reset when the machine is switched off and on from the mains switch (only if the causes that
generated it have been eliminated).
Alarm
 is reset when the machine is switched off and on from the user interface or from the main switch
