During the steam generation process, temperature keeps constant at
120C.
When the water inside the generator starts to decrease, temperature will
increase and thermostat interrupts power at 140C and it steps in again
when
the temperature drops to 125C.
Total
duration of step is 10 minutes.
Normal Operation
In case of thermostat failure,
thermofuse
interrupts power at 260C.
In case of thermostat and
thermofuse failure, relay
interrupts power after 10
minutes.

•Generator is activated for 10
minutes with the relay on the card.
•First steam generation is seen
within approx. 1-2 minutes.
•Generated steam enters into the
drum from behind the drum.
•If the water inside the generator
finished within 10 minutes, thermostat
temperature reaches 140C and it
stops the current of the generator,
later if the temperature decreases to
125C, it steps in again.
•Next step is taken after 10 minutes.

3.5 Water Level Sensor
An analog water level sensor supplied by 5 V is used. This sensor ensures instant
determination of water level by means of frequency values it generates corresponding to the
built up pressure. There are frequency values corresponding to all pressure values. Infinite
number of levels can be determined by an analog water level sensor. Subject to the selected
program, temperature and auxilliary function, water levels vary according to the wash criteria
of designed programme.
Analog water level sensors, in general sense, are elements to turn pressure-displacement.
Analog water level sensors generate frequency modulation as an output.
It basically consists of 2 capacitors, 1 coil and a rotator on itself or on the control system it is
connected to.
Pressure increase pushes a ferrite part in the sensor, into the coil. Thus, coil winding's
L(inductance) value changes and the value of the sensor-rotator system changes. In this
way, analog value of pressure can be measured.
Quantity of hot water to be taken in the machine in the programmes is controlled by water
counters. The task of water level sensor is to perform basic controls such as deciding to take
in water again, check the heater safety level, door opening level or foam level.
If there is an error in water counters or connections thereof, water is taken in by water level
sensor.
Cable inputs
is in the form of 5VDC / Data / GND.
Operation Voltage : 5 VDC
When empty, 625 ± 2 Hz should be read as

3.8 . Wash Motor
3.8.1 Atlas Motor
Picture 3.12 Motor (Atlas motor)
Picture 3.13 Integrated control board
Brushless motor is used. Motor stator consists of 3-phase coil and magnets are on the rotor.
Rotor position is detected from askoll-type hall sensor, stator windings are enegized with the
help of an inverter. In Atlas version,
Rotor position is detected without using hall sensor and stator windings are enegized with the
help of an inverter.
Along with the main board, there is an askoll-type motor driver card integrated on the motor.
However, motor card is discrete in Atlas type. While the motor and the motor card can give
service separately in Atlas type, service can be given in groups in the Askoll type as the
motor and the motor card are integrated. Motor speed is provided through communication of
the motor card and the main board with each other. Main board is the prevailing unit; what
the motor reference speed will be is determined by the main board.
However, all other control algorithms required for motor drive are realized by the motor driver
card. While the motor speed measurement is performed with the help of hall sensor in askoll
type, speed is detected thanks to software in atlas type without using an additional sensor.
Under abbnormal conditions (such as permanently locked rotor), thermic element is used to
protect the motor from overheating. Also, locked rotor condition is detected by the software to
ensure protection

3.10 Heater
It is used to heat up the water in the drum.
Since it is an electronically controlled machine, there are two thermic protectors
(thermofuses) at heater inputs.
When the heater operates dry, thermic element that is overheated open circuits the heater.
Open circuited heater cannot be reused. To prevent waterless operation of heater "during
heating", heater safety water level (Psafety) is defined in the microprocessor. When the
water level measured by the water level sensor falls below defined Psafety level, heater is
deactivated.
When the water temperature read by NTC reaches "selected temperature", heater is
deactivated by the microprocessor.
Operation Voltage : 230VAC 50-60 Hz
Power : 1950W
Resistance : 26W ± 3Ω

3.13 Liquid Dosing Pump
A liquid dosing pump supplied with 220 VAC is used for dosing liquid detergent and
softener. This is a piston pump. The pump motor makes a rotation movement to
make the piston, which is connected to a crank, move in a linear direction. The liquid
taken from the liquid detergent or softener container fills the empty section between
the pump cylinder and the piston. Every time the piston moves up and down, the
liquid taken will have been dosed and moved to the chamber in the door body. Then
the pump will stop and in the water intake step, through the showering holes on the
door body, the liquid detergent or the softener with water in the door body will be
transferred to the central powder detergent compartment in the drawer, and then to
the detergent box.

is full, and if the liquid level in the compartment is low, they go down to let the user
know that liquid detergent or softener must be filled. The floats are detected by the
sensors located under the detergent box. The check valves found at the rear end
of the softener and liquid detergent compartments prevent the spillage of the liquid
in the compartments when the drawer is open. Once the drawer is seated and
pushed back, there will be a flow line from the area shown as the softener and
liquid detergent inlet to the compartment at the backside of the detergent box. If
liquid detergent will be filled, the valve of the system at the back of the box will
open to let the detergent flow in, while softener entry is allowed when the valve is
closed. Before dosing, the pump will start to operate and move the piston to
transfer the liquid coming from the pump liquid entry to the temporary liquid dosing
section, which is located on the door body. When dosing is complete, the pump
will stop and main wash water will be taken in. The water taken will extract the
detergent in the temporary compartment to transfer it to the drawer from the
showering area. The washing liquids will be transferred from the drawer to the
detergent box, and then to the drum through the drum inlet hose. With the water
taken, all liquid residues on the flow line will be transferred to the drum as well.
This way, the channels where water and liquids will flow through in the next
washing and rinsing steps will be cleaned. Moreover, the liquid detergent and
softener will be prevented from mixing with each other, delivering unwanted
results. The dosing principle is the same for softener. Only when the washing will
be performed with powder detergent, the liquid detergent must be unselected on
the interface. Or, when liquid detergent will be dosed, there should be no powder
detergent in the main wash compartment. Otherwise, liquid detergent and powder
detergent will be taken in together.
