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).
