18. Descaling
Your IMPRESSA features an integrated descaling program. The clean-
ing operation will take some 40 min.
Original JURA descaling tablets which are specially designed for
the descaling program of your IMPRESSA are available at your
authorized dealer. Please note that machine defects or residues
in the water cannot be excluded if you use inappropriate
descaling agents.
If the IMPRESSA needs descaling, the corresponding message is
displayed.
You can still draw off coffee or hot water/steam and start the
descaling program later.
Before starting the descaling program, the machine must be
switched off. Once started, the descaling operation must not be
interrupted.
When using the descaling agent, immediately remove any
splashes or drips from sensitive surfaces, i.e. natural stone and
wooden surfaces, or take appropriate precautions.
In any case wait until the descaling agent is used up and the
tank is empty. Never refill descaling agent.
