3 COMPONENT OPERATING PRINCIPLES
3.1.1 Electronic Board Assembly
Picture 3.1 Power board
Picture 3.2 Display board
Picture 3.3 Vector board
Electronic board assembly comprises
the following:
•Power board
•Display board
•Vector motor board and
the extension cable.
The power board is designed to drive all
components and find high-voltage
circuits. Power is distributed to all high-
voltage components on the product, and
the mains input comes here.
The display board allows the user to
select programmes and other auxiliary
functions, as well as carrying out main
board functions.
Wash programs which are written onto
the microprocessor on the display board,
washing and spinning motor profiles,
protection algorithms and components
(motor, heater, pump, valves, door safety
lock, ntc, water level sensor,
spinning/temperature selection, water
meter) are controlled. Along with the LED
display, there are also buttons used for
function selection.

3.2 Water Inlet Valve
It is used to get adequate water for the machine when necessary.
Picture 3.4 Water inlet valve
Dual valve is used in the models with one water inlet and without steam
generator,
Triple valve is used in the models with one water inlet and steam generator (the
steam valve feature is explained in the relevant section),
Dual valve and an additional single valve are used in the models with double
water inlet and without steam generator,
Triple valve and an additional single valve is used in the models with dual water
inlet and steam generator (the steam valve feature is explained in the relevant
section),
Valves are activated via the triacs on the electronic board.
They are activated via the both valves in the softener step by use of crashed water
directing system and the water is directed to the medium compartment of the
detergent box.
3.3 Water Level Sensor
An analog water level sensor which is fed by 5 V voltage is used. This sensor ensures
that the water level is determined instantly with the frequency values which it generates
against the pressure created. There are frequency values corresponding to the all
pressure values. An infinite number of levels can be determined in the analog water
level sensor. Water levels change according to the wash criteria of the designed
program depending on the selected program, temperature and auxiliary function.
Analog water level sensors are pressure –displacement inverter components in
general.
Analog water level sensors generates frequency modulation as output.
There are basically 2 capacitors, 1 coil and an inverter circuit on itself or the control
system to which it is connected.
Pressure increase pushes a ferrite part inside the sensor into the coil. Therefore L
(inductance) value of coilwinding changes and the output value of the sensor –inverter
system changes. Therefore pressure value can be measured in an analog manner.
