To obtain the best ef ciency, quality and performance of the machine, you should always follow the
cleaning and care instructions provided in this manual.
Turn off the power switch when cleaning the exterior of the machine.
All external surfaces should be cleaned with a wet cloth that will not get out bers, threads or scratch the
machine.
Do not use aggressive cleaning detergents, solvents or degreasers. They can damage the machine.
Important:
Once a day or after 8 hours from the last dispensing of coffee, the following cleaning tasks must be
performed for maintaining the quality and performance of the water system in the machine:
Brewing Group: Place the empty porta- lter (without coffee) in the group head and dispense hot
water for one minute.
Steam wand: Position the wand outside the drip tray and open the steam tap for around one minute.
Hot water outlet: Place a container under the water outlet and open the tap for 20 seconds.
Daily cleaning
Rinse the group and porta- lter without detergent. (only using the membrane and hot water)
Clean the external surfaces of the machine, pay special attention to the stainless steel parts.
