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.

(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).

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

8.5  Parameters for automatic hood type dishwashers
Sym. Parameter Description Unit Min Max Factory
Default
 Enable “regeneration cycle” key (only for dishwashers with non-
continuous water softener) [See paragraph 9.1 DETERGENT
AND RINSE AID LEVEL SENSORS ACTIVATION].
-01 0

ALARMS ENABLE
0 = alarms disabled (to disable also warnings see  and
);
1 = alarms enabled;
If this function is disabled, faults can be detected so display do not
shows any alarm code.
-01 1
 Air gap with float level sensor normally closed (the level sensor is
closed when the boiler is empty). E.g. the boiler level sensor for
machines with incorporated continuous water softener.
-01 0

Forced start of a resin regeneration cycle (only for dishwashers
with incorporated continuous water softener). [See paragraph 9.2
DISHWASHERS WITH WASH TANK WATER CHANGE FRE-
QUENCY CONTROL].
-02 0

Max. rinse water hardness (only for dishwashers with incorpo-
rated continuous water softener). After modifying, disconnect and
reconnect the machine's main power supply by means of the
main switch. [See paragraph 9.2 DISHWASHERS WITH WASH
TANK WATER CHANGE FREQUENCY CONTROL].

9 SPECIAL FEATURES
9.1 DETERGENT AND RINSE AID LEVEL SENSORS ACTIVATION
By setting the parameter (in the  family) to 1, management of the level sensors located inside the
external detergent and rinse aid tanks is enabled. During the rinse phase, when the rinse aid inside the tank
has finished, the message appears on the display.
When the detergent inside the tank is finished, the message  is displayed and after a number of wash
cycles equal to  (in the  family) the dishwasher inhibits the activation of other wash cycles. There-
fore the detergent level in the tank must be restored.
9.2 DISHWASHERS WITH WASH TANK WATER CHANGE FREQUENCY CONTROL
WARNING:
Function included starting from firmware version 5.00.
If the parameter  (Cycles before drain) of the family  is set to a value higher than , a wash tank
water change frequency control is enabled. The purpose of this function is to display a message telling the
customer when a tank water drain cycle is required. In this way, if the customer does what the machine sug-
gests, washes will be done with sufficiently clean water.
The value set in the parameter  (Cycles before drain) indicates the number of wash cycles possible
between one tank water drain cycle and the next. When the number of wash cycles done since the last tank
water change reaches the value contained in the parameter  (Cycles before drain), the display shows the
message “” at the start of a wash cycle and the message “” at the end of the same cycle. When
these messages appear on the display at the start and end of the wash cycle, a tank water drain cycle must
be done to ensure washes with sufficiently clean water.
WARNING:
If the tank drain cycle is not done, the machine does not shut down, but will continue to do wash
cycles, showing the messages  and   at the start and end of the wash cycle
respectively.
9.3 PERISTALTIC TUBE FITTING AND REPLACEMENT INSTRUCTIONS

STEP 1 - FITTING THE TUBE
1. Position the roller. 2. Insert the tube of the suction part, turning the roller
clockwise.
3. Keep the tube in the seat in the housing and
continue turning the roller clockwise, being
careful not to damage the tube.
4. Keep the tube in the seat in the housing and con-
tinue turning the roller clockwise.
5. Turn the roller a full 360°. 6. Make sure to fit the union in the special seat (deliv-
ery).

STEP 2 - REMOVING THE TUBE
1. Position the roller as shown in the figure. 2. Lift the tube at the suction part and turn the roller at
the same time. Guide the tube, keeping it raised,
and turn the roller.
3. Remove the tube.
