Operating Instructions
Preparing Your Espresso
- Grind Coffee Beans: Use freshly ground coffee beans. For optimal espresso, a fine grind is recommended.
- Fill the Basket: Add your desired amount of ground coffee (typically 15-18g) into the 51mm stainless steel basket. Use the WDT tool to distribute the grounds evenly to prevent channeling.
- Tamp the Coffee: Use the provided tamper to press the coffee grounds firmly and evenly. A consistent tamp is crucial for proper extraction.
- Assemble Portafilter: Attach the filled and tamped portafilter to the bottom of the MiiCoffee Eon machine.
- Add Water: Unscrew the top cap and fill the water tank with up to 80ml of fresh water. You can use cold water for self-heating or pre-heated hot water to conserve battery.
- Start Heating (if using cold water): Long press the power button to begin the self-heating process. The machine will heat the water to 92°C (197.6°F).
- Begin Extraction: Once the water is heated (or if using pre-heated water), place a cup under the portafilter. Double-click the power button to start the pre-infusion and extraction process. The machine will apply 20 bar pressure for optimal espresso extraction.
- Enjoy Your Espresso: Once extraction is complete, your fresh espresso is ready to enjoy.

Troubleshooting
| Problem | Possible Cause & Solution |
|---|---|
| No or slow extraction | Cause: Coffee grounds too fine or tamped too hard. Clogged basket. Solution: Adjust grind size to be coarser. Reduce tamping pressure. Clean the basket thoroughly. |
| Weak or watery espresso | Cause: Coffee grounds too coarse or not enough coffee. Insufficient tamping. Solution: Adjust grind size to be finer. Increase coffee dose. Ensure firm and even tamping. |
| Water leaking from portafilter area | Cause: Portafilter not securely attached. Gasket issue. Coffee grounds on gasket. Solution: Ensure portafilter is tightly screwed on. Clean the gasket area of any coffee grounds. If leaking persists, contact support. |
| Machine not heating water | Cause: Low battery. Heating element malfunction. Solution: Ensure the machine is fully charged. If the issue persists after charging, contact support. |
| Machine not turning on | Cause: Depleted battery. Power button not pressed correctly. Solution: Charge the machine fully. Ensure a long press (approx. 2-3 seconds) on the power button. |
