How to check inlet valve?

Checking a water inlet valve to determine if it is functioning correctly involves a combination of visual inspections and electrical multimeter testing. First, unplug the appliance and shut off the water supply. Inspect the valve body for visible cracks, rust, or mineral leaks. Check the inlet mesh filter screen for hard water sediment clogs. Next, set your digital multimeter to ohms (resistance) mode and test the electrical continuity across the solenoid coil terminals; an open circuit or infinite resistance reading indicates a burned-out coil that requires replacing the entire valve assembly.

Checking a water inlet valve for proper mechanical and electrical operation involves a systematic diagnostic process. Always turn off the electrical power breaker and shut off the home water supply line before inspecting internal appliance components. First, remove the service panel to access the valve and look for visual signs of cracking, mineral crusting, or active water weeping. Second, check the wire mesh filter screen inside the inlet port for clogs. Third, use a digital multimeter set to ohms to test the electrical continuity of the solenoid coils; a normal coil will show a specific resistance value, whereas an open circuit indicates a burned-out winding. Finally, verify power delivery during a fill cycle. You can verify that your checks are complete when you confirm whether the valve accepts water and seals tightly.
