1 KEYBOARDS
1.1 UNDERCOUNTER Style
SETTING MODES:
To enter into one setting mode (Figure 4), (Figure 5) the appliance should be in stand-by: switch on the appli-
ance, no cycles selected. Is useful keep door open to avoid start cycle in case of not simultaneously pressure
of the two keys.

2 MANUAL ACTIVATION OF DETERGENT AND RINSE AID DISPENSERS
When replacing detergents may be necessary activate the dispensers to fill hoses.
2.1 Detergent Dispenser Activation
2.2 Rinse Aid Dispenser Activation
3 RINSE PUMP MANUAL ACTIVATION
Use this function to empty the boiler (if the dishwasher is not to be used for a long time, for maintenance oper-
ation: ex. before replacing main board).
4 DETERGENT AND RINSE AID DOSAGE
In this paragraph is explained how to set the working time for the detergent and rinse aid dispensers.
For each dispenser there are two parameters: the initial time and the time during cycle execution.
4.1 General Parameters
How change the duration:
• Switch OFF and switch ON the dishwasher;
• Enter into the USER SETTING mode by pressing and hold down ON/OFF and BUTTON_1 keys for at least five sec-
onds the display shows  (Figure 9);
Switch on the dishwasher.
Press and hold down BUTTON_2 and
BUTTON_3 keys, after two 'beep' the
detergent dispenser starts work for 20
sec.
Switch on the dishwasher.
Press and hold down BUTTON_1 and
BUTTON_3 keys, after two 'beep' the
rinse aid dispenser starts work for 40
sec.
Switch on the dishwasher.
Close the door and press and hold
down DRAIN and BUTTON_3 keys. A
buzzer signal indicates the rinse pump
activation and the display shows three
blinking lines. Three beeps indicate
the cycle end.

• Press BUTTON_3. The display shows alternatively the symbol  and the duration in seconds (Figure 10) and
(Figure 11);
• Use BUTTON_1 key to decrease the duration and BUTTON_2 key to increase (Figure 11);
• After settled the duration press BUTTON_3 key to store value. The display shows the next parameter (Figure 12) and
the corresponding value (Figure 13);
• In the same way is possible to change the other duration; when finished switch OFF and switch ON.

Example
Suppose there is connected an external detergent dispenser with a probe into the tank. A typical setting
could be:
 the dispenser is not activated during filling tank;
 the dispenser is supplied during washing phase and the probe automatically dose the right
detergent amount.
5 COUNTERS
This Parameter Family collects cycle counters and water consumption counters.
For water consumption counters a flow meter must be installed. See (calibration parameter) into 
section (8 OTHER PARAMETERS).

5.1 Counters
Sym. Parameter Description Unit Min Max Factory
Default

Cycles performed counter.
 symbol and two numbers blink consecutively. The cycle number
is obtained by joining the two numbers.
Ex.  → → means 10042 cycles executed.
-

Cycle counter (resettable).
This counter is similar to but is resettable by user (see 
parameter below).
-

Water Consumption (only for dishwashers with incorporated continuous
water softener).
Counts m3of water consumption.
[m3]

Water Consumption (only for dishwashers with incorporated continu-
ous water softener).
Counts litres of water consumption.
The total consumption is given by adding [m3] and [l] values.
[l]

Water Consumption: resettable counter. [present up to software version
3.12]
Counts the litres of water and is resettable by user (see  parame-
ter below).
[l]

Reset resettable counters:  and 
To reset put 1 this parameter, switch off and then on again:  and
 will show zero. Note that  is used to count cycles for
 message (see next parameter, ).
-

Store thousand of cycles after that  message appears on dis-
play.
Ex. If this parameter is settled to 20, message appears when
 reach 20.000 cycles.
-
 Drain/Cleaning cycles performed.
Similar to  but counts Cleaning Cycles. -
 Numbers of cycles that can be made after a regeneration cycle (only for
dishwashers with non-continuous water softener) [See paragraph 9.1
DETERGENT AND RINSE AID LEVEL SENSORS ACTIVATION.].
-20

Regeneration cycle counter (only for water softener dishwasher)
[See paragraph 9.2 DISHWASHERS WITH WASH TANK WATER
CHANGE FREQUENCY CONTROL].  only counts efficient
regeneration cycles, i.e. those carried out with salt in the special con-
tainer (only for dishwashers with incorporated continuous water sof-
tener)
-

Counter of regeneration cycles done without salt in the special con-
tainer. (only for dishwashers with incorporated continuous water sof-
tener) [See paragraph 9.2 DISHWASHERS WITH WASH TANK
WATER CHANGE FREQUENCY CONTROL].
