machine stops dispensing water.
14 The machine will now heat up again. When the lights in the drink icons light up continuously, the
machine is ready for use again.
15 Install and activate a new AquaClean water filter in the water tank (see 'Activating the AquaClean
water filter (5 min.)').
-When the descaling procedure is finished, the AquaClean light flashes for a while to remind you

What to do if the descaling procedure is interrupted
You can exit the descaling procedure by pressing the on/off button on the control panel. If the
descaling procedure is interrupted before it is completely finished, do the following:
1Empty and rinse the water tank thoroughly.
2Fill the water tank with fresh water up to the Calc / Clean level indication and switch the machine
back on. The machine will heat up and perform an automatic rinsing cycle.
3Before brewing any drinks, perform a manual rinsing cycle. To perform a manual rinsing cycle, first
dispense half a water tank of hot water by repeatedly tapping the hot water icon (Fig. 14) and then
brew 2 cups of pre-ground coffee without adding ground coffee.
If the descaling procedure was not completed, the machine will require another descaling
procedure as soon as possible.
