Preparing the coffee machine for use

Selecting the display

You can choose from the following options:

On: the display will always show the date and time (even when the machine is switched off).

Off: the date and time are not displayed when the machine is switched off.

Night dimming: the date and time are only displayed between the hours of 5:00 and 23:00.

^Touch the arrow sensors until the option you want is highlighted. Touch the OK sensor.

The coffee machine will use more energy depending on the option you choose for the display. Information about this will appear in the display.

"Set-up successfully completed" will appear in the display.

"Fill and replace the water container" will appear in the display.

^Fill the water container with fresh, cold tap water.

Tip: Please continue to work though the further steps outlined in the operating instructions so that you can familiarise yourself with the coffee machine and set it up for your specific requirements.

Water hardness

The water hardness level indicates how much calcium is dissolved in the water. The higher the calcium content, the harder the water, and the harder the water, the more often the coffee machine will need to be descaled.

The coffee machine measures the quantity of water and steam used. The number of drinks which 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.

The machine has four programmable levels:
