You can adjust the fill levels of each drink (tea/coffee Espresso Choco). It seems not be shown in any manual - but here is what you do. 1. Open the machine door. 2. Switch off the machine at rear 3, Hold down coffee button and switch on the machine. 4. After around 5 seconds the display will say volume 1: 5. Cycle through the volume settings by pressing the coffee or choco buttons for up and down. 6. Press the espresso to goto volume 2 and 3 (2 being espresso and 3 being choco) 7. After you have set the desired fill levels close the main door and the levels will be set for good.
