Aquaclean Water Filter - Philips LatteGo 4400 Series User Manual

Lubricating the brew group
To improve your machine's performance, we suggest that you lubricate the brew group every 2 months, to
ensure that the moving parts continue to move smoothly.
1 Apply a thin layer of grease on the piston (grey part) of the brew group (Fig. 32).
2 Apply a thin layer of grease around the shaft (grey part) in the bottom of the brew group (Fig. 33).
3 Apply a thin layer of grease to the guiding rails on both sides (Fig. 34).

AquaClean water filter

Your machine is AquaClean enabled. You can place the AquaClean water filter in the water tank to preserve
the taste of your coffee. It also diminishes the need for descaling by reducing limescale build-up in your
machine. You can purchase an AquaClean water filter from your local retailer, from authorized service
centers or online at www.philips.com/parts-and-accessories.
AquaClean filter status indication
When the AquaClean is active, the status of the AquaClean filter is always visible on the screen as a
percentage.
-
If the status of the AquaClean filter is 10% or less, the screen shows a message for 2 seconds each time
you switch on the machine. This message advises you to buy a new filter.
-
If the status of the filter is 0%, the machine asks you to replace the AquaClean filter every time you
switch on the machine.
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.
