What is a dishwasher water inlet valve?
The water inlet valve controls the flow of water into the dishwasher. It is responsible for allowing water to enter the dishwasher during wash programs and cycle and halt the flow when necessary, ensuring proper operation and water management.

If your dishwasher exhibits the following symptoms, it is likely a sign of a faulty water inlet valve.
- Less water flowing into the dishwasher.

How to replace a dishwasher water inlet valve?
Follow the steps mentioned below to replace a faulty dishwasher water inlet valve.
- Turn off the dishwasher’s power supply by unplugging the main power cord. Remove the screws securing the toe kick at the bottom front of the dishwasher to open the service panel.
