Display shows “ADD WTR” or “ADD WATER” and unit will not start brewing even though the reservoir appears full.

Safety first: Unplug the coffee maker before cleaning internal parts or removing covers.

• 1. Verify reservoir seating: Remove the water reservoir completely and reseat it firmly. Make sure it is fully down and aligned with the base contacts or sensor area.
• 2. Clean the reservoir and float: If your GE model uses a floating indicator, remove the reservoir and gently shake it. If the float is stuck, soak the reservoir in warm water with a little white vinegar for 20–30 minutes, then rinse thoroughly. Ensure the float moves freely.
• 3. Descale the sensor area: Fill the reservoir with a 1:1 mixture of white vinegar and water. Run a cleaning cycle if available, or start a brew cycle without coffee (if the unit allows). This helps dissolve mineral buildup on the internal water level sensor.
• 4. Inspect sensor wiring (advanced): With the unit unplugged, remove the base or rear cover to access the water level sensor (often a small switch or electronic sensor under the reservoir area). Check for loose connectors and reseat them.
• 5. Replace sensor if needed: If the message persists and wiring is intact, the water level sensor assembly may need replacement. Order the correct GE water level sensor for your model.
