Dishwasher does not fill with water; you hear humming or nothing at all after starting.

Safety First: Turn off power and close the water supply valve before disconnecting hoses.

• Verify water supply: Confirm the under-sink shutoff valve is fully open and other fixtures have water.
• Inspect inlet hose: Check for kinks or crushing behind the dishwasher.
• Clean inlet screen: Disconnect the hose at the dishwasher and rinse the inlet screen to remove debris.
• Test fill: Restore connections, open the valve, restore power, and start a cycle to see if water enters.
• When to call for service: If there is still no fill and you hear a faint click or hum, the inlet valve may need replacement.
