Scale deposits naturally form in your coffee maker. Regular descaling helps protect your coffee maker and ensures it a longer life. It will also help maintain a quality of coffee that remains constant over time.
Follow the instructions in your personal instruction manual for descaling your machine as techniques vary according to the model you own. We recommend using the descaling product provided by the manufacturer. For a daily average usage of 4 cups and if the water is hard, we recommend descaling your machine at least every 3 months. If you live in an area where the water is very hard, you may wish to descale more often.
After following the instructions in the user manual for starting the appliance, make sure that your electrical socket is working by plugging another appliance. If it still does not work, do not try to dismantle or repair the appliance yourself and take it to an approved repair centre.
An expresso has a stronger aroma than a "normal" coffee. In fact, an expresso can be distinguished by its rich aroma and the creamy foam on the surface of the cup. This requires a pressure of 15 bar (achieved only by espresso machines), water heated to 90-92°C and finely ground and measured coffee (7 g per cup).
The sign of a true Espresso is the froth which is created by pressure within the machine whilst the coffee is being made. The pressure is measured in bars (from 1.5 to 19) so the higher the bar pressure the richer and thicker the froth.
