Setting the water hardness
ATTENTION
Device damage due to calcification
Without a decalcification cartridge, the device may cal-
cify if the water hardness is set incorrectly.
Always work with a decalcification cartridge.
Set the device to the local water hardness.
Set the device to the current water hardness before us-
ing it in an area with a different water hardness (e.g. af-
ter a move).
Note
Your water board or municipal utilities authority can pro-
vide information on hardness of tap water.
The water hardness setting is stored until a new setting
(e.g. after a move) is made. The device is set to the
highest water hardness (level IV) in the factory. The de-
vice indicates the set water hardness with flash pulses.
Water hardness levels and flash pulses
Hardness °dH mmol/l
range
I Soft 0-7 0-1.3
II Medium 7-14 1.3-2.5
III Hard 14-21 2.5-3.8
IV Very >21 >3.8
hard
Note
The anti-calcification effect of the decalcification car-
tridge is activated as soon as the device is filled with wa-
ter and put into operation. Lime in the water is absorbed
by the granulate in the decalcification cartridge. Addi-
tional descaling is not required.
Note
The granulate in the cartridge can discolour on contact
with water due to the mineral content in the water, which
is no cause for concern and has no negative effects on
the device, cleaning work or the functionality of the car-
tridge.
Note
Do not pause for longer than 15 seconds when setting
as the device will otherwise be set automatically to the
last selected water hardness or the highest water hard-
ness set during initial start-up.
1. Make sure that the device is switched off.
2. Press the ON/OFF button and hold it for 6 seconds.
