The coffee machine needs descaling when the orange LED on the key (steam) flashes. 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 filter (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 filter 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 fixed light.

• Turn the steam knob (8) anti-clockwise.

• Press the key (22) to start descaling, the key (22) starts to flash.

• 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.

• 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.
