10. Descaling

To keep your machine functioning correctly, it must be
periodically descaled. How often this must be done depends
on the hardness of the water. You can find out how hard your
water is by asking the local water board. In the case of hard
water (approx. 20° dH), we recommend that you descale the
machine every three months. For decalcification purposes
we recommend use of the Jura decalcifying tablet. These are
available from your local dealer.
Note: The machine must be descaled if there is a notice-
able reduction in coffee flow and/or the tempera-
ture of the coffee decreases.
Important: The Jura decalcifying tablet was specially designed
for Jura devices and in particular for the decalci-
fication cycle. You can therefore be sure of opti-
mum results.
