If you have hard water and you
use your coffeemaker without a water filter, it should be decalcified regularly. The
frequency depends on the hardness of the water and how often you use your coffeemaker.
When using the water filter cartridge and exchanging it regularly, you normally will not
need to decalcify. However, if your coffeemaker takes much longer than normal to brew, the
appliance has to be decalcified. Important: Replace the water filter with the space
compensator for any decalcification procedure.
Follow the instructions of the manufacturer of the decalcifying agent.
Repeat the procedure as many times as necessary in order to reduce the brewing time per
cup to a normal level.
Allow the maximum amount of fresh cold water to run through at least twice to cleanse
the coffeemaker
