40
Minutes
Please note
• Before use, read the instructions and the labelling on the descaler pack.
• It is important to use De'Longhi descaler only. Using unsuitable descaler and/or performing descaling incorrectly may result
in faults not covered by the manufacturer's guarantee.
• Descaler could damage delicate surfaces. If the product is accidentally spilt, dry immediately.
When the light (B3) comes
on, it is time to proceed descal-
ing the machine. The descaling
cycle can be run in any moment.
Setting the water hardness (see
Section (10)) will increase (harder
water) or decrease (softer water) the
frequency of the need to descale the
machine.
4. Make sure the portafilter is
not attached and position a
container under the brew-
ing unit (A10), hot water
spout (A11) and steam
wand (A9).
