Here's a comprehensive guide to troubleshooting a dishwasher that won't fill with water:

Common Causes and Initial Checks

• Check if the water supply valve is fully open
• Inspect the water inlet hose for kinks or blockages
• Verify the door is properly latched - dishwashers won't fill if the door isn't secure
• Make sure the water pressure is adequate (should be at least 20 PSI)

Components to Check

• Water inlet valve
  • Look for visible damage or mineral buildup
  • Listen for a humming sound when the cycle starts
• Float switch
  • Check if it moves freely
  • Clean any debris that might be blocking it

DIY Troubleshooting Steps

1. Turn off the power to the dishwasher
2. Check the water supply line connections
3. Clean any visible debris from the water inlet
4. Inspect and clean the filter if your model has one

When to Call a Professional

Contact a qualified technician if you:

• Notice electrical issues
• Find damaged components
• Try basic troubleshooting without success

⚠️ Always disconnect power before attempting any internal inspection or repairs.
