How to program the amount of beverage (volume control):

If you wish to adjust the amount of water for each button (for example, to specify the size of a single or double espresso), you can follow these general programming steps:

1. Entering programming mode: Press and hold the "Continuous Flow/Stop" button (the button designated for manual operation and usually located in the middle or at the end) for the first group for 5 to 8 seconds until the button lights start flashing.
2. Calibration setup: Place the portafilter (filter holder) with the ground and pressed coffee under the group head, and place the calibration cup (or scale) below it.
3. Starting the count: Press the button you want to program (such as the double espresso button), and the machine will start extracting the coffee.
4. Saving the quantity: When the desired amount is reached in the cup (e.g., 60 ml), press the same button again to stop extraction. This amount will be automatically saved for future doses.
