First steps to use Display You can choose between the following options: - On: The date and time are always displayed even when the machine is turned off. - Off: The display will go dark as soon as the machine is turned off. - Night dimming: The date and time will be displayed between 5:00 and 23:00. ^ Tap the arrow buttons until the desired display type is highlighted. Tap the OK button. Depending on which option you select, the coffee machine may consume more energy. This is indicated by a message on the display. The display will then show the message "Set-up successful". The display shows the message "Fill and insert water container". ^ Fill the water container with cold, fresh tap water. Water hardness Water hardness is an indication of the amount of minerals dissolved in water. The higher the mineral content, the harder the water. And the harder the water, the more often the coffee machine will need to be descaled. The coffee machine monitors the quantity of water and steam used. The number of beverages that can be dispensed before the machine needs to be descaled will depend on the water hardness level set. Set the water hardness level on the coffee machine to the water hardness level for the local area to ensure that the machine functions correctly and is not damaged. This will ensure that the reminder to descale the machine will appear in the display at the correct time. If unsure of your water hardness contact your local water authority. You can program four hardness levels on the machine: Water hardness Hardness Setting range (hardness level) 0 - 8.7 gr/gal soft (0 - 8.4°dH) soft 1 8.7 - 14.6 gr/gal (8.4 - 14°dH) medium medium 2 14.6 - 21.9 gr/gal hard (14 - 21°dH) hard 3 more than hard 21.9 gr/gal (21°dH) very hard 4 15

Water hardness
Water hardness is an indication of the
amount of minerals dissolved in water.
The higher the mineral content, the
harder the water. And the harder the
water, the more often the coffee
machine will need to be descaled.
The coffee machine monitors the
quantity of water and steam used. The
number of beverages that can be
dispensed before the machine needs to
be descaled will depend on the water
hardness level set.
Set the water hardness level on the
coffee machine to the water hardness
level for the local area to ensure that
the machine functions correctly and is
not damaged. This will ensure that the
reminder to descale the machine will
appear in the display at the correct
time. If unsure of your water hardness
contact your local water authority.
You can program four hardness levels
on the machine:
