I had pressed the CLEAN button on my Multiserve by mistake. What can i do to cancel the descaling mode?

If you press the CLEAN button by mistake you can skip the descaling procedure just following the below steps:

1) Move the lever to "coffee"

2)  remove the water tank and press the "clean" button
3) when the display shows 04 (it would take a minute) press the clean button again
4) after few seconds the unit will emit a beep and the clean light will turn off
