NB: The number and types of wash programmes vary with the configuration of the model.
4.1.1 Automatic programme
Turbidity sensor
Some models fitted with a turbidity sensor can be equipped with a special
“Automatic” programme that optimises the cycle to compensate for the quantity of
dishes loaded and the amount of dirt on them. The sensor is located on the outside of
the sump and directly contacts the water.
The NTC sensor that controls wash water temperature and the infrared
turbidity sensor that checks the turbidity of the water (and thus the amount of dirt
deposited on the dishes) are contained in a single component.
Detection of dirtiness
The degree of turbidity is measured during the cold prewash.
A LED powered by the main board (connector H5) projects a beam of light at a photo receiver.
In the photo receiver circuit (connector H6 on the main board), a current circulates that is proportional to
the amount of light received (and is thus inversely proportional to the degree of turbidity).
The microprocessor measures the signal in the circuit and determines the most appropriate cycle for
the amount of dirt dissolved in the water.
Detection of load
The quantity of dishes loaded (full or 1/2 load)
is detected during the first heating phase in the
washing cycle by measuring the speed of water
temperature increase (NTC sensor, connector H8).

13
Full load: when the slope of the curve is less
than the programmed standard threshold
Half load when the slope of the curve is
greater than the programmed standard
threshold.
Phases in the automatic programme
Shown below are the variations in programme phases which are made as a function of dirt level and
load.

15
4.3 Options
Every dishwasher with the EDW2500 control system is equipped with an “Options” button:
1. When Options button is pressed repeatedly, all available options are displayed in sequence
oAll available options are displayed on the LCD in sequence
oThe LCD shows the current setting for the option displayed

4. Press “OK/START” button to confirm the new setting
oThe system now returns to the cycle selection mode
NB: If “Cancel” button is pressed repeatedly before point 4 is reached, the system exits the options mode
and returns to the cycle selection mode, and no modification is made.
Here is a description of all the options available:
4.3.1 Eco-drying:
this option must be selected every time it is desired, and its availability depends on the duration of the cycle
that will be run. The option is selected by pressing the relative button, and the relative icon then appears on
the LCD. It is available in all programmes with at least 15 minutes of drying time (excluding “Short
Intensive”, “Short”, “Short 30 min”, “Soak” and “Heat plates”):
Drying time is reduced to only 15 minutes
“Energy Label” programmes are shorted by 39 minutes; all other programmes are shortened by 9 minutes
4.3.2 Extra rinse:
this option must be selected every time it is desired. When it is selected, the relative icon appears on the
LCD. It can also be selected from the “Service” mode (see section 8). It is not available in the “Soak” and
“Heat plates” cycles:
A rinse with pulse washing is added that lasts around 9 minutes.
4.3.3 Detergent
•NORMAL
•“3 in 1”: When this option is selected, it remains selected until it is disabled, and the relative icon
appears on the LCD. The option modifies the phases in the programme to optimise performance
when “3 in 1” detergent tablets are used. It is not available in the “Soak” and “Heat plates” cycles:
The programme length and the temperatures are specially varied to dissolve the detergent tablets
Water exchange (dilution drainage) is diminished)
Rinse-aid is not dispensed from the corresponding container
Regeneration (washing of resins) and salt are disabled from the corresponding container
•“Bio”: When this option is selected, it remains selected until it is disabled, and the relative icon
appears on the LCD. The option modifies the phases in the programme to optimise performance
when “bio” (organic) detergent is used and is available in all programmes:
The wash times and certain temperatures are increased (in all programmes except for “Soak” and
“Heat plates”)
4.3.4 Rinse-aid:
When this option is selected, it remains selected until the setting is changed. Only when the “3in1” option is
selected, in case of not satisfying drying results, it enables or disables the delivery of rinse-aid from the
detergent dispenser. If delivery is disabled, the “Put the rinse aid” advisory does not appear on the display”.
4.3.5 Water hardness:
When this option is selected, it remains selected until the setting is changed. Using a sequence of water
hardness values expressed in French degrees, the user can adjust the amount of water loaded into the
machine between regeneration steps. The adjustment is subdivided into 10 levels. If the first level is set,
the regeneration step is disabled and the “Put the salt” advisory does not appear on the display.
4.3.6 Language:
When this option is set, it remains set until the setting is changed. The language, in which the menus,
programmes, options and advisories are displayed and heard, can be changed.

The name of the programme
The time from the beginning to the end of the cycle, in minutes
The number of segments corresponding to the number of phases in the selected wash cycle
The symbols that characterise the programme
START
4. Press the “OK/START” button and close the door
If delayed start has been selected:
The countdown starts: The time decreases by hours [19 hrs – 18 hrs …..1 hr] and by minutes
during the final hour [1 hr - 59 min – 58 min… 0]
When the countdown is over, the machine starts automatically
RUNNING OF
THE CYCLE
5. During the cycle, the Beam on Floor, if featured, will project a beam on the floor

new phase in the cycle.
6. To interrupt a programm in progress:
Open the door carefully
or
Switch the appliance off with S0 button
NB: To restart the programme, close the door and/or press button S0 once again

6 ELECTRICAL COMPONENTS AND FUNCTIONS
6.1 EDW2503 Electronic control system
The EDW2503 electronic control system consists of:
•One central display board with LCD and uses a separate ON/OFF button.
•One main board (fig. A) placed in the lower part of the appliance, anchored to the base by a
plastic support (as for appliances “DIVA” EDW2000/2003/2500).
The “Talkie” version features also an electronic board, placed under the control panel and contained in
a plastic box, specific for the voice control and connected electrically to the speaker positioned on the inner
door.
6.1.1 Functions performed by the mother board
Acquires cycle programming and commands through the input and output boards.
Powers all the electrical components (solenoids, wash pump, detergent/rinse-aid dispenser, drain
pump, heating element, fan motor)
Controls the temperature of the wash water using a signal from an NTC sensor, and controls the
speed of the wash pump using a signal from a tachometric generator.
Monitors the pressure switches and the rinse-aid / salt sensors.
6.1.2 Memories contained in the electronic control system
The main board is equipped with an EEPROM that is external to the microprocessor and which is
used to store data on machine configuration, programming for the cycle, and status of the cycle in case of a
power failure or alarm.
The configuration data is programmed at the factory by a computer with a DAAS interface. This
data determines the operation of the appliance (number and types of programmes, options, LEDs, etc).
