How to Check the Water Inlet Valve

The water inlet valve controls the water flow into your dishwasher. If this valve is faulty, your dishwasher will not let water in. To check it, first, unplug your dishwasher from the electrical outlet for safety reasons.

Locate the water inlet valve: Open the dishwasher door and remove the bottom dish rack to get a better view of the bottom of the dishwasher. The water inlet valve is usually located at the bottom, either towards the left or right side.

Remove the kickplate: The kickplate is a panel at the bottom of the dishwasher. Use a screwdriver to unscrew and remove it.

Disconnect the valve’s wire harness: The wire harness is a plastic connector that provides electrical connectivity to the valve. Carefully pull it apart to disconnect.

Test with a voltmeter: Set your voltmeter to the Ohms setting and touch the probes to the valve’s terminals. If the reading shows no continuity, then the valve is faulty and needs to be replaced.

Replace if necessary: If the valve is defective, consult your dishwasher’s manual for the correct part number and replace it accordingly.

Testing the Float Switch

The float switch prevents the dishwasher from overfilling with water. If this switch malfunctions, it can prevent water from entering the dishwasher.

Locate the float switch: Open the dishwasher door and look towards the bottom of the tub. You should find a small dome-shaped float switch.

Check its movement: Lift the float switch up and down gently to see if it moves freely. If it’s stuck or sluggish, clean around it to remove any debris.

Test for electrical issues: Use a voltmeter to test the float switch for electrical continuity. A lack of continuity means the switch is faulty and needs replacing.

Inspect Hose Connections

Loose or damaged hose connections can also be a reason why your dishwasher is not letting water in.

Locate hose connections: These are usually found at the rear or bottom of the dishwasher. You may have to pull the dishwasher out slightly for better access.

Secure all connections: Use an adjustable wrench to tighten all hose connections. Make sure not to overtighten, as this could cause additional damage.

Look for leaks: If you find any leaks or notice that a hose looks damaged, it’s best to replace it.

Examine the Door Latch

The door latch ensures that the dishwasher door is securely closed, allowing the cycle to start. If it’s not working properly, water may not enter the dishwasher.

Test the latch: Open and close the dishwasher door multiple times to observe the mechanism.

Listen carefully: When closing the door, you should hear a distinct ‘click’ sound, indicating the latch has engaged.

Replacement: If the latch doesn’t make a clicking sound or feels loose, you’ll need to replace it. Consult your dishwasher’s manual for the correct part number.
