11.4. Valve
Valve is an electrical and mechanical component which is designed to
take water from the network system into the washing machine. It is
operated by PCB card.
Nominal voltage 220-240 V
Nominal power 8 VA
Frequency 50-60 Hz
Check the resistance value on the component with multimeter as shown below. Valve water flow rate should be between 6 - 8 L/min. Each valve coil
resistance values should be between 3.3 - 4.2 kΩ.
You can determine the resistance value of the main wash valve by measuring from the large socket which has one blue, one black and
two white cables as shown in the figure below (refers X5 on the wiring diagram). Each valve coil resistance values should be between
3.3 - 4.2 kohm.
