Display shows “H2O” and the coffee maker beeps without brewing.

Safety first: Turn the unit off before removing the reservoir.

Check water supply:

• Remove the water reservoir (if removable) and fill to at least the MIN line with clean, cold water.
• Ensure the reservoir is seated firmly so the bottom valve fully opens onto the base.
• Inspect the reservoir outlet valve for debris or scale; clean gently with a toothpick and rinse.

Fixed reservoir models:

• Open the lid and confirm water is above the MIN mark.
• Check for any floating water level sensor or float that may be stuck; gently move it with a plastic utensil if visible.

Reset: Unplug the unit for 2–3 minutes, plug back in, and attempt a new brew cycle.

If the H2O message persists with a full reservoir and clear outlet, the internal water level or flow sensor may be faulty and require replacement.
