8-Care and Maintenance
To clean the detergent residues, remove the detergent dispenser from its place by
pressing on the area marked on siphon. Wash the dispenser with water and also clean the
dispenser housing before inserting the dispenser to its place.
Figure-6
Clean the siphon (colored piece in the dispenser) every 30-40 washes. Pull out the siphon
by holding from its edges. To prevent clogging, clean the softener residues thoroughly and
make sure that the siphon fits into its place completely before any operation.
Do not leave any metal objects (pins, needles, etc.) inside the drum. These objects may
cause rust on the drum surface. Do not clean the drum with scratching elements.
At the end of the water intake connection module there exists a filter. These filters
prevent any dirt and objects passing into the machine. It is advisable that these filters
should be cleaned every 30-40 washes. To clean these filter, first turn the tap off. Then,
disconnect the hose and clean the filter with a thin brush. If the filter is very dirty, you may
clean it by pulling out with pliers.
To prevent any leakage, have a technician control the hoses every two years. If the
machine is placed at cold ambient temperatures, the water remaining inside the pump and
hose should be removed from the filters. Also to prevent freezing, empty the water intake
hose by disconnecting from taps.

Page 16
Cleaning the Pump Filter
To prevent objects entering into the pump, your machine
comes with a filter system that extends the pump life. It is
advisable that you should clean the filter at every 30-40
washes. Before opening the filter door, disconnect the
power. Open the kick plate cover with a help of a coin
(figure: 7). Place a little pan in front of the filter door to
prevent a little amount of water spilling from the machine.
Remove the filter by turning it counter-clockwise direction
(figure: 7). After cleaning the objects on the filter, place it
by turning clockwise and make sure that it is closed firmly.
Close the kick plate cover by pushing. If the filter does not
fit into its place, water will leak out from the filter.

9-Components
Mechanical Parts:
The tub is made of special plastic material. The tub is became from two parts and is
attached together with special fixing screws on the front side of the main tub. The main
motor is attached to the tub with four bolts. Placed behind the tub (on the right and the left
and one on the top) are three transport security bolt connection slots. There are three
concrete counterweights, one on the top and two on the bottom side of the tub. The drum
is made of stainless steel.
Dynamic system:
The tub is hooked onto the body with two springs. Besides, the tub is attached to the
body from the bottom by two friction type shock absorbers. The duty of the springs and the
shock absorbers is to conduct the vibrations caused at the tub to the body in order to
damp the motion and noise of the washing machine.
Program Controller Group (PWB):
The module is made up of a circuit that controls the all components of machine according
to the selected programs. The all connections are made by colored sockets to prevent the
wrong connections. PWB made by two parts, Main part and Display part. Main part is
coated with insulated material to prevent the board from environmental conditions. Display
part includes the one Dial Encoder for select the programs, LEDs and 7segment display
are indicate the selections, micro switches help program settings.
Main motor:
The main motor is a universal series motor. An electronic module controls it. The motor
speed is adjusted as the triggering angle of the bridge diode on the module depending on
the tacho signal.

Page 20
Triple Solenoid valve:
There is a triple solenoid valve to direct the water to the appropriate detergent drawer
compartment. Water flow is directed to the pre-wash drawer in Pre-Wash programs by pre-
wash valve, water is directed to the main wash detergent drawer in Main-Wash and Rinse
programs by main-wash valve. At the final rinse, water is directed to the softener drawer
by softener valve. There is a regulator inside the softener valve to reduce the flow rate.
Pressure Switch Sensor:
The output frequency of the sensor changes by the water level. The valves operate to
reach the required water levels. If pre-defined frequency level reaches, the valves close by
the PWB/controller.
Heater:
A 1450-watt heater is used. There are two thermo fuses on the heater. If the heater runs
without water inside the tub, the thermo fuse cuts off the line to protect the plastic tub
damages because of the over heating. The thermo fuses are not reusable. If the thermo
fuse cut off the line the heater should be change. Heater is controlled by a relay inside the
PWB.
Door lock:
PTC door-lock is used. When the door is closed, the PTC disk is heated up hence the door
is locked. After the program is terminated, the PTC is cooled down in max.70 seconds and
the door is released. Thus the door is prevented from opening during operation. The
machine does not operate when there is a problem with the door lock.
Pump motor:
It is a Mono-phase synchronous motor. Current is conducted from the program apparatus
at empty-water phase.
