If you have a multimeter, you can use it to test the inlet valve assembly components.

Set the multimeter to the ohm (Ω) setting.

For the first solenoid, test the resistance between the red and blue wires on the white connector.

The acceptable resistance is 360 to 420 Ω.

Repeat the test on the yellow connector for the other solenoid.

The acceptable resistance is 360 to 420 Ω.

To test the flow meter, test the resistance between the red and black wires on the white connector.

The acceptable resistance is 4 kΩ to 30 kΩ.
