Alarm codes for automatic hood type dishwashers
When the alarm
C9
appears, to facilitate fault-finding another parameter providing a more detailed indication has been
introduced.
The parameter is
AL
and is found in the
DBG
family
.
The possible cause of the anomaly can be found (see table below)
according to the value of the parameter
AL
.
With pot washers the cause that generated a
b3
type alarm can also be found.
E.g.: With an automatic hood type the alarm
C 9
appears.
Access the parameter
AL
in the
DBG
family.
