How to Use an F1 Semi-Automatic Coffee Machine’s Key Functions

If you’ve just started using a semi-automatic coffee machine like the F1, you’re likely wondering how to pull a shot, steam milk properly, or get hot water without guessing which knob does what. These basic functions might seem simple—but without clear steps, you could end up with weak shots, scalded milk, or wasted time. Here’s exactly how the key features on your F1 work.

In short: Set your shot size by pressing one of the preset flow buttons after loading the portafilter; steam milk by turning the steam knob counterclockwise (pull it out for more power); get hot water by turning the water knob counterclockwise (pull it out for a quick burst). Each function is controlled via dedicated knobs with clear mechanical actions.

How to Brew a Set-Dose Espresso Shot on the F1

To make a measured espresso shot, start by filling the filter basket (portafilter) with the right amount of ground coffee. Then, insert the portafilter into the group head. Choose one of the machine’s preset flow buttons according to the shot volume you want. Once you press the button, the machine will automatically begin brewing and stop once it reaches the pre-set water volume. If you need to stop the shot early, simply press the Stop button once—this will immediately halt the water flow.

Using the Steam Wand on the F1 Coffee Machine

The F1’s steam wand lets you texture milk for drinks like cappuccinos and lattes. To use it, turn the steam knob counterclockwise—the further you turn, the more steam is released. For a quick burst of high-powered steam, pull the knob outward. To reduce steam or turn it off completely, turn the knob clockwise. This control gives you both precision and the ability to ramp up steam output when needed, such as when frothing larger volumes of cold milk quickly.

Dispensing Hot Water from the F1 Coffee Machine

To get hot water from the F1, turn the dedicated hot water knob counterclockwise—the more you turn, the greater the water flow. For a short, quick release of hot water, pull the knob outward. Turning the knob clockwise decreases the flow or shuts it off entirely. This function is useful for preheating cups, diluting espresso, or making drinks like Americanos without needing a separate kettle.
