It is not enough to have an espresso machine to get coffee. The coffee will not make itself, after all. You obviously need to turn it on. But for that, it is important to understand how the espresso machine works. This is exactly what we invite you to discover through this article.
Stocking your espresso machine
Before starting the preparation of your espresso, you must first add the basic ingredients, which are water and coffee. Depending on the model used, the containers for these can be removable, which generally makes the task easier for users. It should also be noted that coffee can be used in various forms.

The coffee preparation mechanism with an espresso machine
Once the espresso machine is loaded, plug it in and press the power button. The preparation mechanism is then activated, allowing you to obtain your drink in one or two cups a few minutes later. The different steps of this preparation process are as follows. As soon as the “on” button is pressed, an electric charge is sent to the water pump. This allows it to draw the necessary volume of water to prepare the espresso.

The drawn water is directed to a second pump whose role is to compress it and convey it to the solenoid valve and then to the boiler. The water is heated there. The final temperature is generally between 93 and 110 degrees Celsius. Only after that does the infusion with the coffee take place. The resulting drink flows through the opening designed for this purpose. The flow stops once the defined volume is reached. However, it should be noted that the flavor of the coffee obtained depends on the pressure level of the machine. The minimum recommended value is 9 bars.
The operation after coffee preparation
Once you have collected your espresso in your cup, the machine stops. However, the water heating element does not stop. To avoid any unpleasant surprises when the electricity bill arrives, make sure to unplug it once you are finished, especially if you do not plan to use it again soon.
In addition to all this, we will add the extra features that allow, for example, to prepare other drinks besides coffee. We must also not forget the cleaning system, without which the quality of the drinks obtained would leave much to be desired. Therefore, it is essential to choose your espresso machine with the utmost care.
