Descaling - Philips EP 4300 Series Service Manual

Functions/features explanation

Descaling

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.
When the machine needs descaling, a message appears on the display.
1. Touch the clean icon on the user interface and select 'Descaling' in the menu.
2. Follow the instructions on the screen.
3. If attached, remove LatteGo or the milk frother.
4. Remove the drip tray and the coffee grounds container, empty them and put them back into place.
5. Remove the water tank and empty it. Then remove the AquaClean water filter.
6. Pour the whole bottle of Philips descaler in the water tank and then fill it with water up to the Calc /
Clean indication (Fig. 48). Then place it back into the machine.
7. Place a large container (1.5 l) under the coffee dispensing spout and the water spout.
8. Press the start/stop button to start the descaling procedure. The descaling procedure lasts
approximately 30 minutes and consists of a descaling cycle and a rinsing cycle..
9. Wait until the machine stops dispensing water. Refill the water tank when the message appears on
the display. The descaling procedure is finished when the machine stops dispensing water.
10. Install and activate a new AquaClean water filter in the water tank.
11. When the descaling procedure is finished, the AquaClean light flashes for a while to remind you to
install a new AquaClean water filter.
Using the AquaClean filter reduces the need for descaling!
What to do if the descaling procedure is interrupted
You can exit the descaling procedure by pressing the on/off button on the control panel. If the descaling
procedure is interrupted before it is completely finished, do the following:
1. Empty and rinse the water tank thoroughly.
2. Fill the water tank with fresh water up to the Calc / Clean level indication and switch the machine
back on. The machine will heat up and perform an automatic rinsing cycle.
3. Before brewing any drinks, perform a manual rinsing cycle. To perform a manual rinsing cycle, first
dispense half a water tank of hot water by repeatedly selecting the hot water function and then
brew 2 cups of pre-ground coffee without adding ground coffee.
If the descaling procedure was not completed, the machine will require another descaling procedure as soon
as possible.
