JURA uses state-of-the-art RFID technology to enable communication between the filter and the espresso machine. All machines equipped with the Intelligent Water System (IWS ®) automatically recognise the insertion of the filter, automatically switch to filter mode and start the rinsing process. When the filter capacity is almost exhausted, the machine informs the user that the filter needs to be replaced. If the filter is not replaced, the machine activates the descaling mode. After a certain period of use, the machine informs the user that it needs to be descaled. This can only be done if the filter is removed from the water tank.

Limescale is deposited by heating the water. Limescale in the constricted pipes not only slows down the heating process and thus consumes more energy, but can even cause the machine to break down completely. Limescale also has a negative impact on the coffee itself. Although a small amount of calcium carbonate is essential for the taste of coffee, too much gives the water an unpleasant aftertaste and prevents coffee aromas, which are partly caused by the fluctuating temperature of the water.
