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 that comes included in the instruction
manual set. 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, this information can be obtained
from the local water hardness board.
2. Press the touch key ‘MENU’ and press the scroll touch keys until the menu option
“WATER HARDNESS” appears. Confirm the menu option with the touch key
‘OK’.
3. The display shows the current setting. Press the scroll touch keys until the
established hardness level is displayed. 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.
