Descaling the machine
The JURA builds up deposits of limescale over time
and automatically prompts you to descale it when
necessary. The degree of calcification depends on
the hardness of your water.
J
CAUTION
If the descaling agent comes into contact with the
skin or eyes, this can cause irritation.
T
Avoid contact with the skin or eyes.
T
Rinse off the descaling agent with clean
water. Should you get any descaling agent in
your eye, see a doctor.
CAUTION
If the wrong descaling agent is used, the machine
could be damaged and/or traces could be left
behind in the water.
T
Use only original JURA maintenance
products.
CAUTION
If the descaling operation is interrupted, there may
be damage to the machine.

Allow the descaling programme to run to
the end.

If the descaling agent comes into contact with
sensitive surfaces (e.g. marble), damage cannot be
ruled out.
