Important Safety and Operating Instructions

Before operating the Café Aromis 8000 Series, read the separate safety booklet supplied with the machine.

The machine must be used according to its operating, cleaning, and maintenance instructions.

Coffee Bean and Grinder Precautions

• Do not use caramelized or flavored coffee beans because they may damage the machine.
• Adjust the grinder only while the machine is grinding coffee beans.
• Do not turn the grinder adjustment knob more than one notch at a time.
• The manufacturer recommends waiting until approximately 100–150 cups have been prepared before changing the initial grind setting.

Water and Filter Precautions

• Use fresh water in the water tank.
• Do not fill the tank with demineralized, distilled, or mineral water.
• Use the water within one to two days.
• If the machine has not been used for three days or longer, empty and thoroughly rinse the water tank before refilling it with fresh drinking water.
• Prepare the AquaClean filter according to the on-screen instructions before activating it.
• Do not use Brita filters in place of Philips AquaClean filters.

Cleaning and Descaling Precautions

Only suitable cleaning and descaling products should be used.

Warning: Do not use descalers based on sulfuric acid, hydrochloric acid, sulfamic acid, or acetic acid (vinegar).

These substances may damage the water circuit and may not remove limescale correctly.

Failure to descale the machine can also void the warranty.

The LatteGo Pro cleaning program dispenses small jets of hot water. The machine’s displayed instructions must be followed during this operation.

Before First Use

Setting Up the Coffee Machine

Before preparing the first drink, the machine must be assembled and configured.

1. Connect the power cord to the socket at the back of the machine and to the electrical supply.

3. Wait one minute.
4. Count the red squares displayed on the strip.
5. Select the corresponding water hardness level on the machine.
6. Confirm the selection.

The number of red squares selected on the display should match the test strip.

To change the setting later, open:

Menu > Machine Settings > Water Hardness

Select the required level and confirm.

Assembling LatteGo Pro

The LatteGo Pro hot and cold milk systems consist of a milk container, a frame, and a storage lid.

The milk container and frame must be assembled properly to prevent leakage.

Understanding the Wi-Fi Indicator

AquaClean Water Filter

The Café Aromis 8000 Series supports Philips AquaClean water filters.

The AquaClean filter helps maintain the taste of coffee and reduces limescale buildup inside the machine, reducing the need for descaling.

How to Install and Activate AquaClean

The machine does not automatically recognize a newly installed AquaClean filter. Each filter must be activated through the maintenance menu.

Before installation, the machine must be free of limescale.

1. Open the Menu.
2. Select Maintenance.

4. Select AquaClean.
5. Tap Install.
6. Follow the displayed instructions to prepare the filter.
7. Soak the filter in water as directed.

Proper preparation is important. If the filter is not soaked correctly, air may enter the machine instead of water.

This can produce excessive noise and prevent coffee from being brewed.

If the filter activation reminder has expired, the machine must be descaled before a new AquaClean filter can be activated.

When to Replace the AquaClean Filter

The AquaClean filter stops working after approximately 95 liters of water have passed through it.

The machine displays a reminder when replacement is necessary.

Philips also recommends replacing the filter at least every three months, even when the replacement reminder has not appeared.

To replace the filter:

1. Remove the old AquaClean filter from the water tank.
2. Prepare the replacement filter according to the displayed instructions.
3. Install the new filter.
4. Activate it through the maintenance menu.

If the filter was not replaced in time, the machine may require descaling before the replacement can be activated.
