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 https://www.usa.philips.com/c-m-
