2 MANUAL ACTIVATION OF DETERGENT AND RINSE AID DISPENSERS

When replacing detergents may be necessary activate the dispensers to fill hoses.

2.1DETERGENT DISPENSER ACTIVATION

dEt

Switch on the dishwasher.

Press and hold down wash cycle 2 (“H” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) and “L” key (Par. 1.1 DESCRIPTION OF CONTROL PANEL), after two 'beep' the detergent dispenser starts work for 20 sec.

2.2RINSE AID DISPENSER ACTIVATION

rAi

Switch on the dishwasher.

Press and hold down wash cycle 1 (“G” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) and “L” key (Par. 1.1 DESCRIPTION OF CONTROL PANEL), after two 'beep' the rinse aid dispenser starts work for 40 sec.

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 operation: ex. before replacing main board).

	Switch on the dishwasher.
	Close the door and press and hold down Drain / self-cleaning cycle (“M”
	- Par. 1.1 DESCRIPTION OF CONTROL PANEL) and “L” key (Par. 1.1
	DESCRIPTION OF CONTROL PANEL). A buzzer signal indicates the
---	rinse pump activation and the display shows three blinking lines. Three
	beeps indicate the cycle end.

The parameters are divided into two families: user parameters and factory parameters.

In the family there are parameters for adjusting the detergent and rinse aid dispensers and the counters (wash cycles, drain/cleaning cycles, etc. ).

In the family there are all parameters that determine dishwasher operation: boiler and tank working temperature, duration of the phases of each cycle, etc.

To access the parameters menu, the unit must be in standby mode: switch on the unit and check that no cycles are selected. In the programming phase it is advisable to keep the hood open to avoid starting a cycle if the two buttons are not pressed together (see point 2 in the following example).

Example:

With reference to Table 1 ACCESSING THE PARAMETERS MENU assuming the boiler temperature parameter is to be modified.

1.Switch the dishwasher off and then on again;

2.Enter the parameter mode by pressing and holding down the On/ff buttons (“A” - Par. 1.1 DESCRIPTION

OF CONTROL PANEL) and wash cycle 2 (“H” - 1.1 DESCRIPTION OF CONTROL PANEL) for approx. 5 sec. The display shows the message ;

3.Press the wash cycle 2 (“H” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) button to go to the family;

4.Press the button (“L” - 1.1 DESCRIPTION OF CONTROL PANEL) to access the boiler parameters family;

5.Press the button (“L” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) again to display the boiler temperature parameter ;

6.Press the button (“L” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) again to display the boiler temperature parameter value;

7.Use wash cycle 1 (“G” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) and wash cycle 2 (“H” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) to modify the parameter value; use the wash cycle 1 button to decrease the value and the wash cycle 2 button to increase it;

NOTE: If the tank LED is on, the parameter value corresponds to the factory-set value.

8.Press the button (“L” - Par. 1.1 DESCRIPTION OF CONTROL PANEL) to confirm the value and return to the display of parameters.

NOTE: To exit the parameter mode and return to the display of the families, press wash cycle 3 (“I” - Par. 1.1 DESCRIPTION OF CONTROL PANEL).

Similarly it is possible to change the other values; afterwards, switch the machine off and then on again.

5 USER PARAMETERS

5.1DISPENSERS PARAMETERS - DETERGENT AND RINSE AID DOSAGE

In this paragraph is explained how to set the dosage for the detergent and rinse aid dispensers. For each dispenser there are two parameters: the initial dosage and the dosage during cycle execution.

By changing the parameter is possible to set the desiered unit of measure ( =g/l or =seconds). If

= need to set he parameters on the concentration in g/l, while if = parameters correspond to the activation times in seconds.

Sym.	Parameter Description	Unit	Min	Max	Factory Default
	Dispensers unit of measure ( =g/l or =seconds)	-	-	-
	Initial Detergent Dosage (during filling tank)	[g/l]	0	4,00	2,00
		[s]	0	240	55
	Initial Rinse Aid Dosage (starts when tank filled)	[g/l]	0	1,00	0,12
		[s]	0	180	11
	Detergent Dosage During Cycle Execution (during wash phase)	[g/l]	0	4,00	2,00
		[s]	0	182 (*)	5
	Rinse Aid Dosage During Cycle Execution (when refilling boiler)	[g/l]	0	1,00	0,12
		[s]	0	62 (*)	2

(*) Note for external dispensers (if: = ):

•if 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 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 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 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:

•the dispenser is not activated during filling tank;

•the dispenser is supplied during washing phase and the probe automatically dose the right

detergent amount.

5.1.1 Peristaltic tube fitting and replacement instructions

Described below is the procedure for inserting and removing the tubes from the peristaltic pumps, in case of tube replacement.

An exploded view of the parts involved in the tube fitting and removal operations is given below.

Tube

Ruoller

Front box

STEP 1 - FITTING THE TUBE
