SETTING MODES:
To enter into one setting mode (Fig.1.4, Fig.1.5) the appliance should be in stand-by: switch on the
appliance, 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
Switch on the dishwasher.
Press and hold down CYCLE_2 and CYCLE INFINITE keys, after two 'beep' the detergent dispenser
starts work for 20 sec.
2.2. Rinse Aid Dispenser Activation
Switch on the dishwasher.
Press and hold down CYCLE_1 and CYCLE INFINITE keys, after two 'beep' the rinse aid dispenser
starts work for 40 sec.
3. RINSE PUMP MANUALACTIVATION
Use this function to empty the boiler (if the dishwasher is not to be used for a long time, for maintenance operation: ex. before replacing
main board).
Switch on the dishwasher.
Close the door and press and hold down DRAIN and CYCLE INFINITE keys. A buzzer signal indicates the
rinse pump activation and the display shows three blinking lines. Three beeps indicate the cycle end.

4. DETERGENTAND 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.
GEn General Parameters
Sym. Parameter Description Unit Min Max Factory
Default
dIn Initial Detergent Dosage (during filling tank) [s] 0 240 90
rIn Initial Rinse Aid Dosage (starts when tank filled) [s] 0 180 10
dEt Detergent Dosage During Cycle Execution (during wash phase) [s] 0 182(*) 8
rAi Rinse Aid Dosage During Cycle Execution (when refilling boiler) [s] 0 62 (*) 4
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 CYCLE_1 keys for at least five seconds the display
shows GEn (Fig.3.1);
•Press CYCLE_INFINITE. The display shows alternatively the symbol dIn and the duration in seconds (Fig.3.2 and 3.3);
NOTE: If User Interface v.3.00 tank led is on if value correspond to factory default (Default 1, HOOD TYPE).
•Use CYCLE_1 key to decrease the duration and CYCLE_2 key to increase (Fig.3.3);
•After settled the duration press CYCLE_INFINITE key to store value. The display shows the next parameter (Fig.3.4) and the
corresponding value (Fig.3.5);
•In the same way is possible to change the other duration; when finished switch OFF and switch ON.

(*) Note for external dispensers:
•If DEt=181 the detergent dispenser works when WASHING PUMP is being activated; at the same time voltage
is supplied between connectors L17–L19(main terminal box);
•If dEt=182 the detergent dispenser works when LOADING EV is being activated to re-fill boiler level; at the
same time voltage is supplied between connectors L17–L19(main terminal box);
•If rAi= 61 the rinse aid dispenser works when LOADING EV is being activated to re-fill boiler level; at the same
time voltage is supplied between connectors L18–L19(main terminal box);
•If rAi= 62 the rinse aid dispenser works when WASHING PUMP is being activated; at the same time voltage is
supplied between connectors L18–L19(main terminal box);
- For electrical connections refer to electric diagram -
Example
Suppose there is connected an external detergent dispenser with a probe into the tank. A typical setting could be:
DIn= 0 the dispenser is not activated during filling tank;
DEt=181 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 PPL (calibration parameter) into dPA section (§ Other Parameters).
Cnt Counters
Sym. Parameter Description Unit Min Max Factory
Default
CYC Cycles performed counter.
CYC symbol and two numbers blink consecutively. The cycle number is
obtained by joining the two numbers. Ex. CYC → 10 →042 means
10042 cycles executed.
-
cYc Cycle counter (resettable).
This counter is similar to CYC but is resettable by user (see rSt parameter
below). -
nnc Water Consumption. [present up to software version 3.12]
Counts m3of water consumption. [m3]
L Water Consumption. [present up to software version 3.12]
Counts litres of water consumption.
The total consumption is given by adding nnc [m3] and L[l] values. [l]
Lit Water Consumption: resettable counter. [present up to software version 3.12]
Counts the litres of water and is resettable by user (see rSt parameter below). [l]
rSt Reset resettable counters: cYc and Lit
To reset put 1 this parameter, switch off and then on again: cYc and Lit
will show zero. Note that cYc is used to count cycles for CAll message
(see next parameter, nCY).
-
nCY Store thousand of cycles after that CAll message appears on display.
Ex. If this parameter is settled to 20, CAll message appears when cYc
reach 20.000 cycles. -
drn Drain/Cleaning cycles performed.
Similar to CYC but counts Cleaning Cycles. -
rCY Numbers of cycles that can be made after a regeneration cycle (only for
dishwashers with non-continuous water softener) [See paragraph 9.1 resin
regeneration cycle.]. - 20
NRE Regeneration cycle counter (only for water softener dishwasher)
[See paragraph 9.1 resin regeneration cycle / paragraph 9.4 Dishwashers with
incorporated continuous water softener]. -
