DESCALING
When?
Descale the unit regularly, on average every 4 to 6 months. Regularly descaling ensures the quality of your
coffee will be consistent, lowers energy consumption, and extends the espresso machine's working life.
After a usage of 1,000 cycles, the four indicator lights will flash red twice to indicate that the appliance
needs descaling.
How?
You can use descaling product for coffee machines or water and citric acid.
1. Fill the water reservoir to the maximum mark with the descaling product, diluted according to the
instructions on the product packaging. If you use citric acid, fill the reservoir with 2 l of water and 3
to 4 tablespoons of citric acid.
2. Place the portafilter with filter but without ground coffee in the unit.
3. Place a collection container of at least 2 litres under the brewing head and the steam nozzle.
4. Insert the plug in the power socket, turn on the unit, and let it heat up.
5. Press and hold the hot water button for 5-10 seconds until you hear a signal. The appliance is then in
descaling mode.
6. During this descaling process, descaling liquid flows out of the brewing head and the steam nozzle.
This process takes 10-15 minutes. Once complete, the appliance will automatically switch off.
7. The unit must now be flushed with clean water to ensure no lime residue remains. Rinse the water
reservoir and fill it with clean water. Empty the collection container.
8. Repeat the descaling procedure, but now with clean water in the reservoir.
During the descaling process, the pump will switch on and off alternately. This is normal.
