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.
When the orange AquaClean light flashes:
1 Take out the old AquaClean water filter.
2 Install a new filter and activate it as described in chapter 'Activating the AquaClean water filter (5
min.)'.
Replace the AquaClean water filter at least every 3 months, even if the machine does not yet
indicate that replacement is required.

goes on. The start light starts flashing.
3 Tap the AquaClean icon again to deactivate the reminders. The light in the AquaClean icon goes
off.
4 Press the start/stop button to confirm your choice.
5 Press the on/off button to switch on the machine again. The AquaClean reminders are now
deactivated.
Note: The activation of a new AquaClean filter will automatically re-activate the AquaClean reminders.

performance and a longer lifetime of the machine. This also prevents you from having to descale the
machine too often. The default water hardness setting is 4: hard water.
