Display shows “ADD WATER” or water droplet icon; brew will not start even though reservoir appears to have water.

Safety first: Unplug the coffee maker before inspecting the reservoir base.

• Reseat the reservoir:
  • Remove the water reservoir completely.
  • Wipe the bottom mating surface and the base contacts with a clean, dry cloth.
  • Reinstall the reservoir firmly until it clicks or sits flush; ensure it is not tilted.
• Check the float (if visible):
  • Look inside the reservoir for a small plastic float.
  • Shake gently; if it feels stuck, soak the reservoir in warm soapy water and rinse until the float moves freely.
• Clean the outlet valve:
  • Inspect the bottom outlet of the reservoir for coffee grounds or scale.
  • Press the valve pin (if present) under running water to flush debris.
• Test without coffee:
  • Fill reservoir with water, reinstall, and run a water-only cycle to see if the error clears.

If the message persists with a properly seated, clean reservoir, the internal water level sensor or micro-switch in the base may be defective and require replacement.
