How do I know if my water inlet valve is bad?

Common signs include the dishwasher not filling, overfilling, or leaking water. You might also hear a constant humming or buzzing sound even when the dishwasher isn't supposed to be filling. If the water supply is on and the screen filter is clear, a faulty valve is likely.

Can I clean a water inlet valve instead of replacing it?

While some valves have a small screen filter that can be cleaned, the internal components that regulate water flow are generally not repairable or cleanable. If the valve is failing internally, replacement is typically the recommended solution.

What causes a water inlet valve to fail?

Mineral deposits from hard water can build up over time, preventing the valve from opening or closing properly. Electrical failures in the solenoid or general wear and tear from repeated use can also lead to valve malfunction.
