Adding Water and Brewing
The machine can brew with either cold or hot water. The water tank capacity is 80ml.
- Using Cold Water (Self-Heating): Fill the water tank with cold water. Press and hold the power button for 2 seconds. The machine will automatically heat the water to 92°C/198°F (typically 5-6 minutes for 70ml) and then automatically extract the coffee.
- Using Hot Water (No Heating): Fill the water tank with hot water. Double-click the power button to start brewing directly. This saves battery life and time.

Troubleshooting
If you encounter issues with your Omana Portable Coffee Machine, please refer to the following common solutions:
- No Power/Not Turning On: Ensure the battery is fully charged. Connect the machine to a power source and allow it to charge for at least 30 minutes before attempting to turn it on.
- Coffee Not Brewing/Weak Flow:
- Check water level in the tank.
- Ensure the coffee adapter is correctly installed and sealed.
- If using ground coffee, ensure it's not too finely ground or over-tamped, which can block the flow.
- Perform an automatic cleaning cycle to clear any blockages.
- Water Not Heating: Ensure you are pressing and holding the button for 2 seconds for cold water heating. Verify the battery has sufficient charge, as heating consumes more power.
- Leaking: Ensure all components, especially the coffee adapter and water tank, are securely tightened before brewing.
If problems persist, please contact Omana customer support for further assistance.
