11.5. Valve
Valve is an electrical and mechanical component which is
designed to take water from the network system into the wash-
ine machine. It is operated by PCB card.
11.5.1. Technical Features
11.5.2. Checking of Component
Check the resistance value on the component with multimeter
as shown in below pictures.
Valve water flow rate should be between 6 lt/min - 8 lt/min.
Each valve bobbin resistance values should be between 3,3 -
4.2 kohm.
Checking the component
11.5.3. Component Controlling By Con-
nection Measurement
You can determine the ohm value of the main wash valve by
measuring from the blue cable at 5th and white cable at 15th
position or the pre-wash valve by measuring from the black
cable at 14th and white cable at 15th position in the large
socket (refer to 13 Wiring Connection Diagram) as shown in
belows figures.
Each valve bobbin resistance values should be between 3,3 -
4.2 kohm.
Nominal voltage 220 - 240 V
Nominal power 8 VA
Frequency 50-60 Hz
Rated flow: 7 lt/min (±15 %)
Operating water
pressure 0.0,3 - 1 Mpa
