When you use the machine for the first time, the AquaClean light starts flashing
orange. This indicates that you can start using the AquaClean water filter. If you do
not activate an AquaClean water filter, the light will switch off automatically after a
while.
Once you have installed the filter and activated it with the AquaClean icon, the
AquaClean light turns blue to confirm that the AquaClean water filter is active.
When the filter is exhausted, the AquaClean light starts flashing orange again to
remind you to replace the filter with a new one.
When the orange AquaClean light is off, you can still activate an AquaClean filter,
you will need to descale the machine first.
Activating the AquaClean water filter (5 min.)
The machine does not automatically detect that a filter has been placed in the water tank.
Therefore you need to activate each new AquaClean water filter that you install with the AquaClean
icon.
When the orange AquaClean light is off, you can still activate an AquaClean water filter, but you will
need to descale the machine first.
Your machine has to be completely limescale-free before you start to use the AquaClean water
filter.
Before activating the AquaClean water filter, it has to be prepared by soaking it in water as described
below. If you don't do this, air might be drawn into the machine instead of water, which makes a lot of
noise and prevents the machine from being able to brew coffee.
1Shake the filter for about 5 seconds (Fig. 38).
2Immerse the filter upside down in a jug with cold water, shake/press it a bit and wait until no more
air bubbles come out (Fig. 39).
3The filter is now prepared for use and can be inserted into the water tank.
4Insert the filter vertically onto the filter connection in the water tank. Press it down to the lowest
possible point (Fig. 40).
5Fill the water tank with fresh water and place it back into the machine.
6If attached, remove the LatteGo.
7Place a bowl under the hot water spout/milk frother.
8Press the AquaClean icon for 3 seconds (Fig. 41). The start light starts to pulse.
9Press the start/stop button to start the activation process.
10 Hot water will be dispensed from the hot water spout/milk frother (3 min.).
11 When the activation process is finished, the blue AquaClean light goes on to confirm that the
AquaClean water filter has been activated correctly.
Replacing the AquaClean water filter (5 min.)
After 95 liters of water have flowed through the filter, the filter will cease to work. The AquaClean light
turns orange and starts to flash to remind you to replace the filter. As long as it flashes, you can
replace the filter without having to descale the machine first. If you do not replace the AquaClean
water filter, the orange light will go out eventually. In that case you can still replace the filter but you
first need to descale the machine.
