SYMBOL
Appliance maintenance
The appliance counts the number of cycles performed and the LED comes on to alert the user that
maintenance is required.
These are inspection and maintenance operations, scheduled every 1000 cycles, which must be
performed by authorised staff to keep the appliance safe and in good working order.
These maintenance operations are not covered by the product Warranty, which does not include
the replacement of components which deteriorate due to normal wear and tear.
No Salt
Salt must be added to the water softener reservoir in the chamber.
Salt is necessary to enable the softener to reduce the hardness of the intake water.
The intake water hardness is set on the appliance parameters on the basis of the information
provided by the user. Regular checks (every 6 months/year) to ensure that the initial characteristics
are retained are recommended. If the characteristics change, contact authorised technical staff for
modification of the parameters accordingly.
Alarm
The machine displays an anomaly, which can be generated by a fault or by the detection of
abnormal conditions.
The segment display shows "AF" plus a code number identifying the alarm triggered.
The alarms table below details the components which may have caused the event for each alarm
code, to simplify diagnostics and troubleshooting.
The following is a list of the alarms which may occur on the device, they are of two types: "FATAL"

number.
