Electromagnetic field occurs due to movement of pressur-
ized membrane. The spring moves vertically by nucleus
due to electromagnetic field. The water level is regulated
according to the frequency changes of the spring by elec-
tronic card.

Push the door lock slider with screwdriver.

Select the 1st program and start the machine.

Unplug power cable when as soon as water intake finishes
and drum begins to rotate.

Check the water level inside the drum with ruler. It should
be 10 cm ±1.

The washing machine has an asynchronous motor. It is
controlled by the PCB. It is essential to check the motor for
correct diagnosis and quick servicing. In the below picture,
socket points on the motor is shown to measure with multi-
meter.

Check the motor tacho terminals on the motor socket with 
multimeter as shown in the picture above.

 You can determine the ohm value by measuring from the 
pink cable at 16th and red cable at 6th position in the large 
socket (refer to section 12 Wiring Connection Diagram) as 
shown on right figure. For resistance values, refer to the 
table below.

Check the motor stator terminals on the motor socket with 
multimeter as shown in the picture.

 You can determine the ohm value by measuring from the 
black cable at 18th and brown cable at 8th position in the 
large socket (refer to section 12 Wiring Connection Dia-
gram) as shown on right figure. For resistance values, 
refer to the table below.

Door lock is activated at the beginning of the program in 
order to prevent the door from opening. Locking is gener-
ated by supplying power to PTC-bimetal, after max 6sec 
(220V), the bimetal will be warm and ready to close the 
contacts. Thus the first impulse to the solenoid will allow 
the contact to close and consequently the slider will be 
locked by the pin of the sliderlock. The second impulse 
causes no electrical and mechanical modifications. It can 
be unlocked by the third impulse; the contact is opened 
even if the PTC-bimetal remains energized.

• In case of lack of electric energy during a washing cycle, the 

PTC-bimetal assembly will cool down and after minimum 60 
sec (considering previous power supply of 30 sec min and 
T=20 

°C) the door will be unlocked and thus can be opened.

• In case the door is closed when current comes back, the 

PTC-bimetal assembly will heat again, the slider lock will 
lock, the contact will close and the program will continue 
from where it stopped.

Nominal voltage          250 V

Check the resistance value on the component with multi-meter as shown in below figures. Resistance value on the (PTC over-

load + solenoid) should be 240

Ω ±20% at 25 °C. That resistance value can be measured from terminal 3-4 (refer to section12 

Wiring Connection Diagram).

This socket shows the connection between terminal 3-4 (See wiring diagram below). The resistance read from terminal 3-4 is the 

resistance of PTC overload plus resistance of solenoid.
