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 wires from it at the connector.

The acceptable resistance is 360 to 420 Ω.

Repeat the test on the connector for the other solenoid.

The acceptable resistance is 360 to 420 Ω.

To test the flow meter, test the resistance between the wires from it at the connector.

The acceptable resistance is 4 kΩ to 30 kΩ.
