Before performing the descaling cycle, remove any water softener filters from the tank (3).

Stay close to the machine for the entire duration of the descaling cycle as user intervention may be required, e.g. to refill the tank. The descaling and rinsing cycle lasts 20 minutes in total.

The coffee machine indicates when a descaling cycle is required based on the set water hardness (for information on setting the water hardness, see the “Setting the water hardness” paragraph). 

The coffee machine must be descaled when the key (29) flashes orange. The warning will be displayed whenever the machine exits the standby state, until the descaling procedure is performed. However, coffee, steam/hot water can still be dispensed. 

To perform a descaling cycle, proceed as follows: 

• The descaler contains acids that can irritate the skin and eyes. 

• Scrupulously follow the manufacturer's instructions and safety warnings on the packet in the event of contact with skin or eyes.
