When the machine stops showing the filter activation message, 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 using 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.
1 Tap the 'Clean' icon and use the up and down arrows to select 'AquaClean'.
2 Tap the OK icon to confirm.
3 Tap the OK icon again when the activation screen appears. Follow the instructions on the screen.
4 Shake the filter for about 5 seconds (Fig. 45).
5 Immerse the filter upside down in a jug with cold water and shake/press it (Fig. 46).
6 Insert the filter vertically onto the filter connection in the water tank. Press it down to the lowest possible
point (Fig. 47).
7 Fill the water tank with fresh water and place it back into the machine.
8 If attached, remove the LatteGo (specific types only).
9 Place a bowl under the hot water spout/milk frother.
10 Press the start/stop
11 Hot water will be dispensed from the hot water spout/milk frother during 1 minute.
12 The filter is now successfully activated.
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 status
indicator drops to 0% to remind you to replace the filter. As long as the AquaClean status indicator is shown
on the display, you can replace the filter without having to descale the machine first. If you do not replace
the AquaClean water filter in time, the AquaClean indicator goes out after some time. In that case you can
still replace the filter but you first need to descale the machine.
When the AquaClean status indicator drops to 0% or when the machine reminds you to replace the
AquaClean filter:
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.
Descaling procedure (30 min.)
Please use Philips descaler only. Under no circumstances should you use a descaler based on sulfuric acid,
hydrochloric acid, sulfamic or acetic acid (vinegar) as this may damage the water circuit in your machine and
not dissolve the limescale properly. Not using the Philips descaler will void your warranty. Failure to descale
the appliance will also void your warranty. You can buy Philips descaling solution in the online shop at
www.philips.com/coffee-care.
When the machine needs descaling, a message appears on the display.
