Descaling
Descaling is necessary to keep your espresso
maker running efficiently.
• Your espresso maker should be descaled on
a regular basis.
• Use caution when descaling your espresso
maker as the acid substance within the
descaling powder may damage worktops or
any other surface it comes in contact with.
• The warranty of this machine does not
include espresso makers that do not
function, or do not function properly,
because descaling has not been carried
out.
We would advise you to use the Krups
descaling solution that is available from Krups.
Descaling depends on the hardness of the
water, but also on the frequency of use.
- To descale follow the following method:
• Remove the Claris-Aqua Filter System
cartridge (accessory not provided) if you
have fitted one.
• Unscrew the grid from the head of the
machine and clean it

• Dissolve a packet of KRUPS descaling

pour the whole batch into the empty water
container.
