The water level sensor isn't making proper contact. The fix is to reset the reservoir connection.
FIX:
- Remove the water reservoir completely.
- Re-seat it firmly. Ensure it's properly installed on the hook on the side or back of the brewer and pressed down firmly into the water reservoir base.
- Ensure the Configurable Water Reservoir Latch on the back is installed securely.
- Press START BREW to resume the cycle.
IF THAT DIDN'T WORK: The sensor or internal connection may be faulty. Contact Ninja Customer Service at 1-877-646-5288.
HEADS UP: "Add Wtr" means the system doesn't have enough water to complete your selected brew size. If the reservoir is truly full and correctly seated, the error is a sensor issue.
