The E4 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.
E If you are using a CLEARYL Smart filter cartridge, you will not
be prompted to descale. However, should you need to
descale the E4, first switch the machine to descaling mode
(see section 7 “Maintenance – Switching the machine from
filter mode to descaling mode”).
Non-recommended descaling agents (e.g. vinegar) may contain
substances that could damage the machine or leave residues.
T Use only original JURA descaling tablets. These are formulated
especially for your machine.
