Descaling
Limescale builds up in the coffee machine during use. The limescale buildup in the machine will depend on the hardness of your local water supply. Limescale must be removed regularly.
The machine will guide you through the descaling process. Various instructions will appear on the display, e.g. you will be prompted to empty the drip tray or fill the water container.
Descaling is required and takes approximately 20 minutes.
During the descaling program, water containing descaling agent will run out of the main dispenser and the hot water spout. This is followed by an activation period before a little more water with descaling agent is dispensed, etc.
The coffee system will remind you on the display when the descaling program needs to be carried out. The display will show "No. of uses until appliance needs descaling: 50". The remaining number of beverages that can be made before descaling will show in the display after each beverage is made.
^Tap the OK button to confirm this message.
When the number of remaining beverages is 0, the coffee system will lock. The display will read, "Descale the appliance".
You can turn the coffee machine off if you do not want to run the descaling program at this time. However, no more beverages can be prepared until the descaling program has been completed.
