Before using your dishwasher for the first time:
1. Ensure that the electrical and water connections comply
with the installation instructions
2. Remove all packaging from inside the appliance
3. Set the water softener
4. Pour 1 litre of water inside the salt container and then fill
with dishwasher salt
5. Fill the rinse aid dispenser
The water softener
The dishwasher is equipped with a water softener designed to
remove minerals and salts from the water supply, which would
have a detrimental or adverse effect on the operation of the
appliance.
The higher the content of these minerals and salts, the harder
your water is.
Water hardness is measured in equivalent scales, German
degrees (°dH), French degrees (°TH) and mmol/l (millimol per
litre - international unit for the hardness of water).
The softener should be adjusted according to the hardness of
the water in your area. Your local Water Authority can advise
you on the hardness of the water in your area.
The water softener must be set in both ways: manually, using
the water hardness dial and electronically, using the function
buttons on the control panel.
a) Setting manually
1. Open the dishwasher door.
2. Remove the lower basket from the dishwasher.
3. Turn the water hardness dial to position 1 or 2 (see table).
4. Replace the lower basket.
The dishwasher is factory set
at position 2.
b) Setting electronically
(The dishwasher must be switched off)
The dishwasher is factory set at level 5.
1. Press the On/Off button. The indicator lights of the
programme selection buttons will illuminate and 2 horizontal
lines (--) are visible in the digital display (setting mode).
If in the digital display is visible the number of a programme
(1 - 2 - 3 etc..), this means that a washing programme is set.
The programme must be cancelled: press simultaneously
the function buttons 2 and 3 for about 2 seconds. The
indicator lights of the programme selection buttons will
illuminate and 2 horizontal lines will appear in the digital
display, this means that the set washing programme has
been cancelled and the machine is now in setting mode.
2. Press simultaneously function buttons 2 and 3, until the
indicator lights of the function buttons 1, 2 and 3 start
flashing.
3. Press function button 1, the indicator lights of function
buttons 2 and 3 turn off while the indicator light of the
button 1 goes on flashing, the digital display indicates the
current level and a sequence of intermittent audible signals
are heard.
The current level is indicated by the number visible in the
display and the number of intermittent audible signals
heard.
Example:
dis 5 audible signals = level 5.
4. To change the level, press function button 1. Each time the
button is pressed the level changes. (For the selection of
the new level see the chart).
Examples:
if the current level is 5, by pressing button 1 once, level 6 is
selected.
if the current level is 10, by pressing button 1 once, level 1
is selected.
5. To memorise the operation, switch off the dishwasher by
pressing the On/Off button or wait about 60 seconds after
which the dishwasher will automatically return to setting
mode.
