Descale the espresso machine every 4 or 5 weeks. Regular descaling ensures a better taste
and aroma of your coffee and extends the operating life of your espresso machine. Follow
these steps for descaling:
Prepare a water solution of citric acid: use 1 litre of water and 4 tablespoons of citric acid.
Pour the mixture into the water tank.
Attach the filter holder with an empty filter to the receptacle and install the drip tray with
the grate. Place an empty container on the grate.
Plug the espresso machine to the mains and turn on. Wait for the water to preheat.
turn the water flow on by pressing the (2c) button, wait for some time, repeat three times,
empty the dish as needed
Turn on the steaming switch (2d). Wait for the steam to preheat. Place an empty container
under the steam jet nozzle and release hot steam for about 1 minute.
Discard the unused water with citric acid. Add clean drinking water to the tank.
Repeat the descaling process with pure water only (by passing hot water through the filter
holder and venting steam) to remove residues of citric acid.
Remove the drip tray, turn off the espresso machine, unplug it from the mains and
wait
until it cools down completely
