3. Securely replace the water tank cover.

3.2 Coffee Extraction

The machine offers both heated and direct extraction modes.

• Check Battery Level: Single-click the power switch to display the current battery level.
• Heated Extraction (for cold water):
      a. Add cold water to the tank.
      b. Double-click the power switch to enter the water boiling mode. The indicator light will blink orange.
      c. The machine will automatically heat the water (approx. 3-6 minutes) and then extract the coffee.
• Direct Extraction (for hot/cold water):
      a. Add pre-heated hot water or cold water to the tank.
      b. Press and hold the power switch for 2 seconds to enter direct extraction mode. The indicator light will blink green.
      c. The machine will extract the coffee directly without heating.

Place the coffee warehouse (cup) under the machine's nozzle to collect the extracted coffee.

4. Maintenance and Cleaning

Regular cleaning ensures optimal performance and longevity of your espresso machine.

4.1 Daily Cleaning

1. After each use, disassemble the capsule adapter/powder bin and the coffee cup.
2. Rinse all removable parts (capsule holders, powder bin, coffee cup) thoroughly with clean water.
3. Wipe the main body of the machine with a damp cloth. Do not immerse the main body in water.

4.2 Automatic Cleaning Cycle

To clean the internal system:

1. Fill the water tank with clean, fresh water (without any coffee capsules or powder).
2. Run the machine through a normal extraction cycle (either heated or direct extraction) to flush out any residue.
3. Repeat if necessary until the water runs clear.

4.3 Storage

Ensure all parts are clean and dry before storing the machine. Store in a cool, dry place away from direct sunlight.

5. Troubleshooting

• Machine not turning on: Ensure the battery is charged. Connect to a power source using the USB-C cable.
• Coffee not extracting: Check if the water tank is filled and if the coffee capsule/powder bin is correctly assembled and sealed. Ensure the battery has sufficient charge.
• Water not heating: Make sure you double-clicked the power button for heated extraction mode. Ensure the battery has sufficient charge for heating. Heating requires more power than direct extraction.
• Weak coffee: Check the coffee grind size (if using powder) or capsule type. Ensure the water level is appropriate for the desired strength.
• Leaking: Ensure all parts are securely tightened and properly aligned. Check for any damage to seals or gaskets.

If problems persist, please contact customer support.
