Danby ice maker displays 'Add Water' or similar indicator even though the reservoir is full.

Safety first: Unplug the unit before accessing the reservoir sensor.

Steps to fix false 'Add Water' alerts:

• Reseat reservoir: Remove and reinstall the water reservoir, ensuring it is fully seated and engaging any internal switches.
• Clean the float and sensor: Remove the float from the reservoir (if removable) and clean it and the guide tube with warm soapy water. Rinse thoroughly.
• Check for damage: Inspect the float for cracks that could allow water inside, making it sink. Replace if waterlogged.
• Test the float switch: With the unit unplugged, test the float switch or reed sensor for proper operation using a multimeter. Replace if defective.
