Inspect and Secure Water Inlet Lines and Valve

1. Locate the water inlet valve, typically found at the rear of the refrigerator near the water supply connection.

2. Inspect the water lines connected to the valve for any contact with the cabinet or other components that could cause vibration.

3. Use plastic zip ties or foam insulation tape to secure loose water lines away from vibrating surfaces.

4. Ensure the water inlet valve itself is firmly mounted to the refrigerator frame, as a loose valve can create a buzzing sound during water intake cycles.
