How to descale the machine?

Fill the water tank with the mixture and switch on the machine. Then fill the tank with fresh, clean water up to the MAX mark and operate the coffee maker again.
In stand-by mode, press the CALC button briefly to start the descaling process. The CALC button indicator flashes and the display shows the symbol (clock) . Press the CALC button to stop descaling after a few minutes (or during the operation). The descaling process is complete.
Note: The buzzer beeps twice and the machine goes into standby mode when the filter paper door is not closed properly.
