When the dishwasher is first
installed
Before using your dishwasher for the first
time:
• Ensure that the electrical and water
connections comply with the installation
instructions
• Remove all packaging from inside the
appliance
• Set the water softener level
• Pour 1 litre of water into the salt container
and then fill with dishwasher salt
• Fill the rinse aid dispenser.
If you want to use combi detergent
tablets such as "3 in 1", "4 in 1", "5 in
1" etc... set the Multi tab function
(see "Multi tab function").
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,
Clarke degrees, 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.
