Before performing the descaling cycle, remove any water softener filters present inside the tank (7).

Stay near the machine for the entire duration of the descaling cycle since you may be required to fill the tank, for example. The entire descaling and rinsing cycle lasts approximately 40 minutes.

The coffee machine signals when it is necessary to carry out a descaling cycle on the basis of the water hardness set (For setting of the water hardness, see the “Setting water hardness” paragraph). If the button (14) lights up with a fixed orange light, it means that a descaling cycle is necessary, so as not to alter the taste of the coffee and damage the machine. However, coffee, steam/hot water can continue to be dispensed. Proceed as follows to perform the descaling cycle:

• Remove the filter-holder (20) from its seat

• Place a container with a capacity of at least 600 ml under the dispensing unit (21) and another with a capacity of at least 600 ml under the steam wand (22).

• Fill the tank (7) to level 1 L indicated on the back of the tank and add a dose of descaler indicated by the manufacturer for 1 litre of water.

• Press keys (11) and (14) simultaneously for 5 seconds to enter the programming menu.

• Turn the lever (15) anti-clockwise to the steam intensity position.

• Buttons (11), (12) and (13) switch off, while the button (14) flashes with an orange light.

• Press (14) to start the descaling cycle.

During the descaling cycle, the machine will make a few pauses to allow the descaler to act effectively Wait for the end of the cycle.

• The descaling cycle ends when the button (14) turns white.

• Remove the tank (7) and thoroughly rinse it under running water to remove any traces of descaler.

• Re-mount the tank and fill it up to “MAX” with clean water to perform the rinse cycle, then press the key (14) to start this cycle. The button (14) flashes.

• The rinse cycle ends when the key (14) lights up with a fixed white light.

• Re-position the lever (15) in the vertical position. The machine is ready for use again.

• 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.
