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.

Setting the water hardness

We advise you to adjust the water hardness to the water hardness in your region for optimal
performance and a longer lifetime of the machine. It also prevents you from having to descale the
machine too often.
Use the water hardness test strip supplied in the box to determine the water
hardness in your region:
1 Immerse the water hardness test strip in tap water or hold it under the tap for 1 second (Fig. 42).
2 Wait 1 minute. The number of squares on the test strip that turn red indicate the water hardness
(Fig. 43).
Set the machine to the correct water hardness:
1 Press the on/off button to switch off the machine.
2 When the machine is switched off, tap and hold the aroma strength icon until all lights in the icon
go on (Fig. 2).
3 Tap the aroma strength icon 1, 2, 3 or 4 times. The number of lights that are on should be the same
as the number of red squares on the test strip (Fig. 44). When there are no red squares on the test
strip (so all squares are green) please select 1 light.
4 When you have set the correct water hardness, press the start/stop
5 Press the on/off icon to switch on the machine.
Since you only set the water hardness once, the aroma strength function is used to select the water
hardness. This does not affect the aroma strength of the drinks you make afterwards.

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 Calc / Clean light starts to flash slowly, you need to descale the machine.
1 If attached remove LatteGo or milk frother.
2 Remove the drip tray and the coffee grounds container, empty them and put them back into place.
3 Remove the water tank and empty it. Then remove the AquaClean water filter.
4 Pour the whole bottle of Philips descaler in the water tank and then fill it with water up to the Calc
/ Clean indication (Fig. 45). Then place it back into the machine.
5 Place a large container (1.5 l) under the coffee dispensing spout and the water spout.
6 Press the Calc / Clean icon for 3 sec. and then press the start/stop
