Descaling is required when the  "Ready to start? (=20min)" message appears on your screen. The frequency of descaling depends on the hardness of the water in your area.

It is always recommended to use the De'Longhi SoftBalls, perform the water hardness test and use our eco-friendly descaling solution, De'Longhi EcoDecalk

The descaling procedure takes around 20 minutes to complete, so be sure to have enough time to finish the process. 

STEP-BY-STEP Guide:

Important! Before use, read the instructions and the labelling on the descaler pack. 

It is important to use the De'Longhi descaler only. Using an unsuitable descaler and/or performing descaling incorrectly may result in faults not covered by the manufacturer's guarantee. 

If present, remove the SoftBalls before descaling the appliance.
