4.4 Descaling
The coffee machine needs descaling when the
orange LED on the key (steam) ashes.
The warning will be displayed every time
the machine exits the stand-by status, until the
descaling procedure is performed.
Proceed as follows to run the descaling cycle:
• Empty the water tank (11) completely and
remove the water softening lter (if present).
• Fill the water tank (11) up to MAX with a
solution of water and descaler following the
doses recommended by the manufacturer.
• Remove the lter holder (3) and position a
container under the dispenser (2) and the
steam wand (7).
• Turn the machine on by pressing the ON/
OFF button.
• As soon as the machine is ready, hold the
key (22) down for 10 seconds until the
orange LED has a xed light.
• Turn the steam knob (8) anti-clockwise.
• Press the key (22) to start descaling, the key
(22) starts to ash.
• The descaling cycle automatically performs
a series of rinse cycles at intervals to remove
lime scale from the inside of the coffee
machine, continuing until the tank (11) is
empty.
• The descaling cycle stops and the white
LED (22) switches on.
• Remove the water tank (11), empty it and
rinse it out.
• Fill the tank (11) with water to the maximum
level mark and insert it into its housing.
• Position an empty container under the steam
wand (7), an empty container under the
dispensing unit (2) and check that the steam
knob (8) is horizontal.
• Press the steam key (22) again to start the
rinse cycle.
• When the tank (11) is empty, it means that
the rinse cycle has ended and the machine
goes back to ready status.
• Turn the steam knob (8) clockwise.
Personal injury hazard.
• The descaler contains acids that
can irritate the skin and eyes.
• Follow the manufacturer's
instructions and safety warnings
on the packet scrupulously in
the event of contact with skin or
eyes.
• Use descaler products
recommended by Smeg to
prevent damage to the coffee
machine.
