Dishwasher does not fill with water; you may hear a humming or clicking, then the cycle cancels; F4E1 or water inlet error appears.

Safety First: Turn off power and shut off the dishwasher's water supply valve under the sink.

Check household supply:

• Verify the shutoff valve to the dishwasher is fully open.
• Ensure there are no kinks in the stainless or plastic supply line.

Inspect inlet valve:

• Remove the lower access panel to locate the water inlet valve where the supply line connects.
• Disconnect the supply line (have a towel ready) and inspect the inlet screen for debris. Clean gently with a soft brush; do not damage the screen.
• Check the wiring connector to the valve; ensure it is tight and not corroded.

Test and replace if needed:

• If you have a multimeter and are qualified, test the valve coil for continuity. An open coil indicates a bad valve.
• Replace the inlet valve if the coil is open, the valve is leaking, or cleaning the screen does not restore filling.
