4.2.6 Setting the water hardness

The DESCALE message is displayed after the appliance has been operated for a factory
set period of time calculated on the basis of the maximum quantity of lime scale which
may be contained in the water used. If necessary, this period of operation can be
extended, making descaling less frequent, by programming the appliance based on the
actual lime content in the water used. Proceed as follows:
1. Remove the "Total Hardness Test" strip (in front of your manaul). Then dip it fully in
the water for a few seconds. Remove it and wait around 30 seconds (until it changes
colour and a number of red dots are formed). For example, if there are 3 red squares
on the test strip, you must set the water hardness level to 3.
If you no longer have a water hardness test, you can fi nd the data in the table
below.
2. Press the MENU button. Then press the NEXT button repeatedly until the appliance
displays WATER HARDNESS 4.
3. Press the CHANGE button repeatedly until the number coincides with the number of
red squares on the test strip.
4. Press the OK button to confi rm the value. The coffee maker is now programmed to
provide the descaling warning when necessary, based on the actual hardness of the
water.
Information on the hardness of the water in your area can be obtained from the
local water board. In the table below you can fi nd the water hardness setting your
machine requires.
