How to Replace a Water Inlet Valve on Your Dishwasher

Step 1: Shut off electrical power and water supply to the dishwasher

Unplug the dishwasher or shut off the house circuit breaker for the dishwasher.

To verify that power is disconnected, make sure the control panel doesn’t light up when you press a control button or the power button.

Find the water supply valve for the dishwasher under the sink (or in the basement). Close the valve to shut off the water supply going to the dishwasher.

Step 2: Remove the outer door panel and control panel

With the dishwasher door open, remove the Torx screws from the inner door panel. Support the outer door panel with one hand as you remove the final 2 screws so the outer door panel doesn't fall.

Separate the outer door panel and control panel slightly from the inner door panel, and rest the outer panel on the floor while you disconnect the user interface control wire harness from the control panel.

Pull off the outer door panel and control panel.

Step 3: Remove the bottom front access panel and toe panel

Using a nut driver, remove the screws that hold the bottom front access panel and toe panel in place.

Pull the access panel and the toe panel forward and remove them.

Step 4: Disconnect the water supply line

Place a towel under the water inlet valve.

Remove the dishwasher water supply line from the inlet valve assembly using the channel-lock pliers.

Wipe up any spilled water.

Step 5: Remove the water inlet valve

Remove the water inlet valve mounting screw and pull the water inlet valve out of the mounting bracket.

Pull the water inlet valve slightly forward to access the wire harness and water inlet tube connections.

Release the locking tab and disconnect the water inlet valve wire harness.

Release the wire clamp on the water inlet tube and pull the inlet tube off the water inlet valve.

Remove the water inlet valve.

Step 6: Install the new water inlet valve

Connect the water inlet tube to the new water inlet valve and secure the inlet tube with the wire clamp.

Plug in the wire harness.

Place the water inlet valve in the bracket and secure it with the mounting screw.

Step 7: Connect the water supply line

Connect the water supply line to the water valve and tighten it securely using channel-lock pliers.

Open the water supply valve and check the water supply line connection for leaks. Tighten the water supply line connection to stop leaks.

Step 8: Reinstall the bottom front access panel and toe panel

Position the toe panel on the dishwasher and then position the access panel in front of the toe panel. Insert the mounting screws and tighten the screws firmly.

Step 9: Reinstall the outer door panel and control panel

Position the outer door panel and control panel close enough to the inner door so you can reconnect the user interface control wire harness.

Reconnect the user interface control wire harness and attach the outer door panel and control panel to the inner door panel.

Reinstall the mounting screws.

 Tip: Use the longer screws to secure the control panel.

Step 10: Restore electrical power

Reset the house circuit breaker or plug in the dishwasher to restore electrical power.
