3.11. Turbidity sensor (High power sensor)
Control both the temperature and the turbidity of the
washing water.
Positioned externally on the sump in direct contact
with the water.
Fitted with an NTC sensor for control of the
temperature.
Fitted with an infra-red system for control of the
turbidity of the water (i.e. the quantity of dirt in
the water).
Constantly transmits the two signals to the electronic
control system for processing.
By correctly combining the signals received from
the two sensors (NTC and turbidity), enables the
appliance to perform "automatic" washing cycles
which automatically optimize the washing cycle
according to the type of load, the quantity of the load
and the degree of soiling.
The light is collected by a new technology and
guides the light into the measurement zone.
- Use of larger LEDs
the light area increases from 3 to 20sqmm
small dirt pieces cannot block the light
beam anymore
- LEDs are located in a colder area
- less temperature fluctuations around the
LED’s
- higher precision during measurement
- improved signal stability
- measurement during higher pump speed is
possible
OLD NEW
1- Dirt pieces 2- Temperature between 15-70°C in
water
3- Constant 23°C measured, because
LEDs are outside the hot water area
4- The temperature sensitive electronical
components are out of the water
zone, where the temperature is colder
and more constant

3.12. Global Dispenser
Details
The new dispenser have the following main features:
• Low voltage driving - 5VDC => Safety improvement
• Multiple dosage => Performance/Quality improvement
• Sliding lid => Performance/Quality
improvement
It’s present on dishwashers with “Thin inner door”.
Assembly process as today. It is screwed in to door cut out in
an automated line.
1- Multi dosage -> No knob 2- Sliding door. Improved
access to wash
compartment and no
interaction with basket.
3- Rinse aid level detection

3.14. Door Lock with Auto Door Opening – 2nd generation
Doorlock
The door lock is fixed on the upper front
cross bar, springs are adjusted to 50/60N.
Doorlock with Auto door
opening
The mechanism to open the door is
integrated in the locking device to
guarantee process control
