Possible Causes

Water reservoir not fully seated on base, Water level below minimum sensor, Faulty water level sensor or float in reservoir, Blocked reservoir outlet port

How to Fix / Troubleshooting

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

Check water level and seating:

  • Remove the water reservoir and fill it at least to the MIN or SMALL CUP line.
  • Inspect the bottom outlet valve for debris or coffee grounds; rinse thoroughly.
  • Reinstall the reservoir firmly, ensuring it clicks or sits flush on the base.

Clear airlocks and blockages:

  • With the reservoir removed, inspect the water inlet on the coffee maker body for scale or debris.
  • Use a damp cotton swab to gently clean the inlet area.
  • Reinstall the reservoir and gently tap it down to ensure good contact.

Test brew:

  • Plug the unit back in, power on, and select a small brew size.
  • If ADD WATR still appears despite a full reservoir, try a full descale cycle to clear internal sensors.

If the message persists after cleaning and descaling, the water level sensor or reservoir assembly may be defective and should be replaced.
