Care & maintenance

Empty the drip tray

Daily

1
Empty the tray
Remove and empty the drip tray daily, or sooner if the red full-tray indicator rises above it.

Rinse the brew group

Weekly

1
Remove the brew group
Switch off the machine. Remove the water reservoir and open the service door. Press PUSH and pull the brew-group handle to remove the brew group.
2
Rinse and air-dry
Rinse the brew group thoroughly under the tap, carefully cleaning its upper filter. Let it air-dry; do not dry it with a cloth.
3
Refit the brew group
Align the arrow on the yellow circle with the black arrow and N; if needed, lower the lever until it touches the bottom of the brew group. Slide the brew group along its rails until it clicks, without pressing PUSH. Close the service door and refit the water reservoir.

Keep in mind

Do not dry the brew group with a cloth: fibres can collect inside it.

Check the ground-coffee compartment

Weekly

1
Check for a blockage
Check the pre-ground-coffee compartment for blockage each week.
2
Clear the compartment if blocked

Keep in mind

Unplug the machine before clearing the compartment.

Wash the coffee grounds container

Clean the brew group with a tablet

Monthly

1
Use the specified tablet
Use only Philips coffee-oil-removal tablets for this cleaning procedure.
2
Start the cleaning program
Tap Clean, use the arrows to select 'Zetgroep reinigen', and press OK. Follow the on-screen instructions.

Keep in mind

This monthly tablet treatment is separate from the weekly water rinse.

Lubricate the brew group

Every 2 months

1
Remove the brew group
Switch off the machine, remove the water reservoir and open the service door. Press PUSH and pull the brew group out by its handle.
2
Apply Philips lubricant
Apply a thin layer to the piston (grey area), the shaft beneath the group (yellow area), and the guide rails on both sides.
3
Refit the brew group
Check that the arrow on the yellow circle at the side of the brew group is aligned with the black arrow and N. Slide the brew group along the side guide rails back into the machine until it clicks. Do not press the PUSH button. Close the service door and refit the water reservoir.

Replace the AquaClean filter

Every 3 months

1
Replace on time
Replace the filter at least every three months, or sooner when the filter reaches 0% or the machine asks. Replace it after more than 95 litres of water have passed through it. Remove the old filter. If the filter-status light has disappeared, descale the machine before fitting and activating a replacement.
2
Start activation
Tap Clean, select AquaClean with the arrows, and press OK. Press OK again when the activation screen appears and follow the display instructions.
3
Prepare the new filter
Shake the filter for about 5 seconds. Immerse it upside down in a bowl of cold water and shake and press it.
4
Fit the filter
Place it vertically on the filter base in the water reservoir and press it fully down. Fill the reservoir with fresh water and refit it.
5
Complete activation
Remove LatteGo if attached and place a bowl under the hot-water spout. Press start/stop. The machine dispenses hot water for one minute to activate the filter.

Keep in mind

The machine must be fully free of scale before using AquaClean.
Soak and prepare the filter before activation to prevent air being drawn into the machine.
Activation dispenses hot water.

Clean LatteGo

After each use

1
Run quick milk cleaning
With LatteGo correctly attached, place a cup under its spout. Tap Clean, select 'Quick milk clean', press OK and follow the display instructions.
2
Wash LatteGo
For washing, remove LatteGo and discard any remaining milk. Press the release button and separate the milk container from its frame. Wash the parts in the dishwasher or under the tap with lukewarm water and washing-up liquid.

Keep in mind

The quick-clean program releases jets of hot water through the milk system.

Empty the coffee grounds container

When the machine asks you to empty the coffee grounds container

1
Empty while the machine is on
Remove and empty the grounds container while the machine is switched on. Wait 5 seconds before putting it back.

Descale the machine

When the machine displays a descaling message

1
Start descaling
Tap Clean and select 'Ontkalken'. Follow the display instructions. Remove LatteGo, then remove, empty and refit the drip tray and grounds container.
2
Prepare the solution
Remove and empty the water reservoir, then remove the AquaClean filter. Pour in the entire bottle of Philips descaler and add water to the Calc/Clean mark. Refit the reservoir.
3
Run both cycles
Place a 1.5-litre bowl under the coffee and hot-water spouts. Press start/stop. Let the approximately 30-minute descaling and rinsing cycles finish; refill the reservoir when the display requests it.
4
Fit a new filter
When the machine stops dispensing and the procedure is complete, install and activate a new AquaClean filter.
5
If the procedure is interrupted
Empty and thoroughly rinse the reservoir. Fill it with clean water to Calc/Clean and switch the machine on. Before preparing a drink, dispense half a reservoir of hot water, then prepare two pre-ground coffees without adding coffee. Repeat the incomplete descaling procedure as soon as possible.

Keep in mind

Do not use descalers based on sulfuric, hydrochloric, sulfamic, or acetic acid (vinegar), because they can damage the water system.
Allow both descaling and rinsing to complete before use.
