3.4 Brewing Espresso
- Press and hold the power button for 3 seconds to turn on the machine. The indicator light will illuminate.
- For Cold Water Heating & Brewing: Press the power button once. The machine will heat the water to 176°F (80°C) and then automatically begin brewing. This process takes approximately 4-5 minutes.
- For Preheated Water Brewing: If you have already added hot water, press the power button twice. The machine will immediately begin brewing. This process is faster than heating from cold water.

5. Troubleshooting
If you encounter any issues with your WONDER FAMILY Portable Espresso Machine, please refer to the following common solutions:
- Machine Not Turning On: Ensure the device is fully charged. Connect it to a USB-C power source and allow it to charge.
- Coffee Not Brewing: Check that the water tank is filled to the appropriate level and that the coffee adapter is correctly assembled and securely attached. Ensure the power button is pressed according to the desired brewing mode (once for heating+brewing, twice for preheated brewing).
- Weak Espresso: Verify that the correct amount of ground coffee (0.18-0.28 oz / 5-8g) is used and that it is tamped properly. For capsules, ensure they are correctly inserted into the appropriate adapter.
- Battery Life Concerns: The machine provides approximately 5 cups of espresso when heating cold water internally. If using preheated water, it can produce up to 150 cups on a single charge. For extended use, consider using preheated water or carrying a power bank for recharging.
