Descaling Procedure (30 Min.) - Philips 4300 serie Benutzerhandbuch

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 in the 'Clean' menu.
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.
