Possible Causes
Reservoir not detected as full enough, Faulty water level sensor, Blocked reservoir outlet, Misaligned reservoir float
How to Fix / Troubleshooting
Safety first: Unplug the coffee maker and allow it to cool.
- Fill reservoir: Remove the reservoir, fill it to the MAX line with fresh water, and reseat it firmly.
- Check outlet: Inspect the reservoir outlet valve for debris or scale. Rinse thoroughly and ensure water flows freely when the valve is pressed (if accessible).
- Clean float: If your reservoir has a visible float, make sure it moves freely and is not stuck by mineral deposits. Soak the reservoir in warm, diluted vinegar if needed, then rinse well.
- Test brew: Plug the unit back in and start a water-only brew cycle. Observe whether E10 reappears.
- If E10 remains: The internal water level sensor or associated circuitry may be faulty. Professional diagnosis and replacement are recommended.
