DIY steps
- Disconnect electrical power to the dishwasher, then shut off the water supply by locating the shut-off valve under the sink and turning it clockwise. Verify the water supply is off by opening the dishwasher door after a brief fill attempt or by relieving pressure at the fitting. Wear protective gloves and safety glasses.
- Identify the actual inlet fitting and disconnect it using the manufacturer-specified method; do not assume it uses a hose clamp. Place a bucket under the valve to catch remaining water, then remove the mounting screws that hold the old valve in place.
- Carefully pull the old valve out of the mounting bracket, taking note of the wire connections. Use a nut driver to loosen any retaining nuts that secure the valve to the bracket. Remove the old valve and set it aside.
- Install the new water inlet valve by reversing the steps above. Ensure the valve is securely fastened to the mounting bracket with the retaining nuts. Tighten the hose clamp to secure the water supply line.
- Reconnect the wire connectors to the new valve, ensuring they are securely attached. Turn the water supply back on and check for leaks at the valve and supply line connections.
- Verify the dishwasher is functioning properly by running a test cycle. Check for leaks and ensure the valve is operating correctly.
- Clean up any spills or debris from the repair, and dispose of the old valve responsibly.
