How do I descale my Dedica?
Descaling is required when the "descale“ red light goes On, on the display. The frequency of descaling depends on the hardness of the water in your area. It's important to perform the water hardness tests, to set the descaling rate on the machine accordingly.
We recommend to always use the De’Longhi water filter, to widen the time between descaling procedures.
The descaling procedure takes around 25/30 minutes to be completed so be sure to have enough time to finish the process. It's highly recommended to use our descaling solution, EcoDecalk, as it contains the correct ingredients to perform a perfect descaling.
Make sure to watch the video or follow the step-by-step guides to properly complete all descaling procedures.
