Dishwasher Not Getting Water

Quick answer

First, check if the dishwasher's water inlet valve is receiving power and if the water supply is on. If the valve is faulty, replace it. Also, ensure the filter and spray arms are clear of debris.

Confirm the symptom

• Dishes are not being cleaned properly
• No water is entering the dishwasher during the wash cycle
• You can hear the dishwasher running but no water is visible inside

Tools and prep

• Screwdriver
• Adjustable wrench
• Flashlight
• Bucket
• Plumber's putty or Teflon tape
• Turn off the dishwasher's power supply
• Turn off the water supply to the dishwasher

Step-by-step troubleshooting

1. Check Water Supply Valve
   Do: Locate the water supply valve under the sink and ensure it is fully open.
   Observe: Water should flow freely when you turn on the valve.
   Means: If the valve is closed or partially closed, opening it should resolve the issue.
   Next: If water still doesn't flow, move to the next step.
2. Inspect Water Inlet Valve
   Do: Check the water inlet valve for any visible damage or blockage.
   Observe: The valve should be free of debris and the solenoid should click when the dishwasher is turned on.
   Means: A non-clicking solenoid or a clogged valve indicates a problem.
   Next: If the valve is faulty, replace it.
3. Test Water Inlet Valve
   Do: Use a multimeter to test the water inlet valve for continuity.
   Observe: The multimeter should show a reading if the valve is working correctly.
   Means: No reading indicates a faulty valve that needs replacement.
   Next: Replace the water inlet valve if it is not working.
4. Check for Clogs in Spray Arms
   Do: Remove the spray arms and inspect for clogs or debris.
   Observe: Spray arms should be clear of any blockages.
   Means: Clogged spray arms can prevent water from distributing properly.
   Next: Clean the spray arms and reinstall them.
5. Inspect the Dishwasher Filter
   Do: Locate and remove the dishwasher filter, then clean it thoroughly.
   Observe: The filter should be free of food particles and debris.
   Means: A dirty filter can restrict water flow.
   Next: Reinstall the clean filter and test the dishwasher.
6. Check the Float Switch
   Do: Ensure the float switch is not stuck in the up position.
   Observe: The float switch should move freely up and down.
   Means: A stuck float switch can prevent the dishwasher from filling with water.
   Next: If the float switch is stuck, clean or replace it.
7. Verify Dishwasher Settings
   Do: Check the dishwasher's settings to ensure it is not in a power-saving or rinse-only mode.
   Observe: The dishwasher should be set to a normal wash cycle.
   Means: Incorrect settings can affect water intake.
   Next: Adjust the settings to a normal wash cycle and test the dishwasher.

Common causes

Parts matching

If you need to replace parts, match these common components:

• Water Inlet Valve: Replaces the valve that controls water entry into the dishwasher
• Spray Arms: Distribute water during the wash cycle
• Dishwasher Filter: Filters out food particles and debris from the water

Purchase replacement parts that are compatible with your dishwasher model.

When to call a professional

• If the water inlet valve is damaged and you are unsure about replacing it yourself
• If the float switch is stuck and you cannot free it
• If the dishwasher still does not get water after replacing the water inlet valve
