Water hardness
A "PLEASE 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 manual).
Dip it fully in the water for a few seconds. Remove it and wait
30 seconds until its colour changes and a number of red dots are
formed. For example, if there are 3 red dots on the test strip, you
must set the water hardness level to 3.
If you no longer have a water hardness test, you can find the data in
the table below.
2. Press the touch key 'MENU' (2) and press the scroll touch keys
(5 and 7) until the menu option "WATER HARDNESS" appears.
Confirm the menu option with the touch key 'OK' (9).
3. The display shows the current setting. Press the scroll touch
keys (5 and 7) until the established hardness level is displayed.
9
Confirm the selection with the touch key 'OK'. The appliance 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. The table below shows the water hardness
setting your machine requires.
