  • Page 33: Component Specifications

    11 Component Specifications 11.1. Drain Pump Drain pump is both a mechanical and electrical component which is used to drain water inside the washing machine. It has an synchronous motor inside. For better performance maintenance, pump filter should be cleaned regularly. Technical features 136 ...
  • Page 34 11.2. Heater Heating element (Resistance) is a component which is designed to regulate temperature of water inside the drum. It has three connections: Phase, neutral and ground con- nections. Technical features Nominal power 2000 W (±5%) Heater type Tubular heating element with NTC-sensor 26.4 ±5% ...
  • Page 35 11.3. NTC Component which sends signals to PCB about the water temperature inside the tub. The Resistance (Ohm) value of the NTC decreases as the temperature increases. Technical features Testing component Check the resistance value on the component with multimeter as shown below. You can determine the ohm value by measuring from the socket with two black cables (referring to X7 on the wiring diagram).
  • Page 36 11.4. Valve Valve is an electrical and mechanical component which is designed to take water from the network system into the washining machine. It is operated by PCB card. Technical features Nominal voltage 220-240 V Rated flow 7 L/min (±15 %) Nominal power 8 VA Operating water pressure...
  • Page 37 11.5. Electronic Pressure Sensor (EPS) 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.
  • Page 38 11.6. Motor 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.
  • Page 39 11.7. Door Lock 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.
  • Page 40 11.8. DC Module Board • DC module electronic board is used as an additional board in DC machine models in order to convert AC voltage to DC voltage and provide bridge and relay components. • Input of DC board is provided by X1 connector and output of board is provided by X2 connector.
  • Page 41 11.9. Circulation Pump The component is used for circulation of water inside the drum in order to increase washing performance. Technical features Nominal voltage 220-240 V Frequency 50 Hz 169,5  (±5%) Resistor (coil) Testing component Check the resistance value on the component with multimeter as shown below. Resistance value should be between 160 - 180 ...
