To de-scale the machine, carry out the following procedure:
1.Mix the de-scaling agent with water according to manufacturer’s instructions and pour the mix
into the machine’s water tank.
2. Place a suitable receptacle under the steam wand.
3.Press the ON/OFF button and wait until the heating process is completed, i.e. when the buttons
with the coffee symbols illuminate steadily.
4.Turn the knob and dispense a cup of hot water. Turn off the machine by the ON/OFF button and
leave in the de-scaling agent for about 10-15 minutes. Repeat steps 3 and 4 until the full amount
of de-scaling mix has been ejected.
5.When the de-scaling procedure is complete, turn the knob clockwise to the stop and turn OFF
the machine.
6. Remove the water tank from the machine.
7.Thoroughly rinse the water tank, fill it under running water, and reinstall it to the machine ensuring
that the clear hose is fully immersed in the water.
8.Press the ON/OFF button to turn ON the machine and wait until the buttons with the coffee
symbols stop blinking.
9.Place a receptacle of adequate capacity under the steam wand.
10. Turn the knob until 2/3 of the tank water has been dispensed.
11.Return the knob to the zero position and allow the machine to reach its operating temperature
again.
12.Use the knob again to dispense the remaining amount of water.
13.Do not forget to return the knob to the off position at the end by turning it clockwise!
14.The final step of the de-scaling process consists in letting hot water flow through the capsule
holder. To do this, simply follow the standard procedure for making caffè lungo, with the capsule
holder installed but with no coffee capsule in it.
De-scaling the natural way
A more environmentally friendly procedure consists in using an easy-to-make mix of water and citric
acid or water and vinegar (do not use vinegar essence).
Mix together 4 parts water and 1 part vinegar or citric acid.
Pour the mix into the water tank and follow the same procedure described above.
