Identifying the Problem

The first step in solving a dishwasher valve not working issue is to identify the problem. The water inlet valve controls the water supply to your dishwasher. If dishes come out dirty or the machine isn’t filling, a faulty valve might be the culprit.

Things You Will Need

To tackle the issue, you’ll need some essential tools:


Adjustable wrench

Teflon tape

Replacement valve (Check your manual for specific part number)

Shut Off the Water Supply

Before you proceed with any plumbing-related repairs, it’s essential to eliminate any potential water hazards by turning off the water supply to your dishwasher.

Locate the Shut-off Valve: This is usually situated under your kitchen sink. You should see two valves—one for hot water and one for cold water. The one connected to your dishwasher is typically the hot water valve.

Turn Off the Valve: Rotate the valve clockwise until it’s in the off position. If the valve is hard to turn, you may need a pair of pliers to give you extra grip.

Unplug the Dishwasher: For safety, ensure that the dishwasher is unplugged from the electrical outlet to avoid any electrical hazards during the repair process.

Check the Valve

The importance of a thorough inspection cannot be overstated when dealing with a malfunctioning dishwasher valve.

Pull Open the Door: Open your dishwasher’s door to full extent to ensure you have complete access to the interior.

Remove the Bottom Rack: Slide out the bottom dish rack and set it aside. This gives you unobstructed access to the dishwasher’s lower section, where the valve is usually located.

Identify the Kickplate: The kickplate is the removable panel situated at the bottom front of your dishwasher. It’s often made of metal or plastic and is held in place by screws at each corner.

Get Your Screwdriver: Select the screwdriver that fits the screws on the kickplate.

Remove Screws: Carefully unscrew each of the screws while holding the kickplate in place. Keep these screws in a safe location, as you’ll need them to reattach the kickplate later.

Identify the Water Inlet Valve: Once the kickplate is removed, you should see the water inlet valve. It will be connected to a water hose and usually have electrical lines leading into it.

Look for Damage: Check the valve for any signs of wear and tear such as cracks, corrosion, or leaks.

Make an Informed Decision: If you see any form of damage or wear, it’s a strong indication that you should replace the valve. Make a note of the valve’s model number or take a photo to help you find a suitable replacement.

Replacing a Faulty Valve

If your valve is damaged and needs replacement, follow these steps carefully.

Position Your Wrench: Use an adjustable wrench to grip the connector where the water supply line meets the valve.

Turn Counterclockwise: Gently turn the wrench counterclockwise to disconnect the water supply line from the valve. You may want to place a towel under the area to catch any residual water.

Unclip Electrical Connectors: If the valve has electrical connections, carefully unclip them. Note how they are connected for easy reinstallation later.

Remove Screws: Use your screwdriver to remove any screws holding the valve in its place.

Wrap Teflon Tape: Take a length of Teflon tape and wrap it around the threads of the new valve several times. This helps prevent water leakage by creating a tighter seal.

Position the Valve: Align the new valve where the old one was located.

Screw in Place: Using your screwdriver, screw in the new valve securely. Make sure it’s tight but don’t overtighten as that may strip the threads.

Reattach Electrical Connectors: If your valve has electrical connections, clip them back in the same arrangement as before.

Use Adjustable Wrench: With your adjustable wrench, reattach the water supply line to the new valve by turning the connector clockwise.

Reassembly: Put the bottom rack back in place. Mount the kickplate, then apply the screws to secure it.

Testing the New Valve

It’s time to test your handiwork to ensure that the new valve functions as it should.

Restore Water Supply: Turn the shut-off valve back to the open position.

Plug in the Dishwasher: Reconnect the dishwasher to the electrical outlet.

Run a Wash Cycle: Select a quick wash cycle and let the machine run.

Inspect for Leaks: During the cycle, check for any water leaks under the dishwasher.
