17. ADJUSTING THE WATER HARDNESS
Important: If the Claris Cartridge is activated (see chapter 16a)
this chapter does not apply.
The water is heated inside the machine. With use, this leads to
calcium deposits forming inside the machine. The display will
remind you when it is time to perform a decalcifying cycle. The
machine is set to level 2 (medium hard water). If you have hard-
er water you need to set it to a higher level. If you have softer
water you can set it to level 1. If you are not sure about the
hardness of your water, ask your local water company for the
"Water Hardness in Grains." 

: grains 2-9     

: grains 10-19 

: grains 20-29

: grains 30+

You can also use the enclosed water hardness indicator strip to
determine the water hardness: 

• Insert the stick for one second into the water you want to 

use. Shake off any access water and wait for one minute.

• If all five fields of the test stick turn reddish, set the hardness 

level to 4. If four fields turn reddish, set the hardness level to 
3. If three or less fields turn reddish, leave the level in 
position 2.

You can change the hardness settings as follows:

• Push and hold the P button (Fig. 3e) until you hear a beep.

monitor is turned off. In this case the machine will NOT remind
you when it is time to decalcify. Turning off the monitor requires
you to use distilled water only or the Claris Filter (chapter 16a).
If you use regular or bottled water the machine will build up cal-
cium. If calcium build-up inside the machine is not removed, it
can lead to a complete machine break down.
