Descaling the appliance
The coffee system must be descaled regularly. The appliance will display a reminder message to descale and will eventually lock if not descaled.
The display will show "Please descale the coffee system. Remaining numbers of servings: 50". This message will now appear after each preparation. If the counter has elapsed to 0, the appliance will be locked.
Select "Descaling" to start the descaling immediately. The descaling takes about 20 minutes. If you want to continue at a later point in time, turn the unit off. The appliance can only be used again once descaling is performed.
Only use the enclosed descaling tablets for descaling. They are specially developed for the coffee system to optimize the descaling. The descaling tablets can be purchased from Miele.
Other agents may damage the machine and affect the taste of coffee and hot water.
The machine could also be damaged.
Use the supplied descaling funnel to protect the appliance front from the descaling agent. Clean up any descaling spills immediately to avoid damage to the appliance front. Thoroughly clean the water tank and the drip tray of descaling residues.
Descaling
For descaling purposes the machine automatically switches from the plumbed function to the water container.
^To descale the unit before it is heated up, select "Descaling" in the main menu.
^To start the descaling process before prompted by the machine (e.g. because of very hard water), select "Care".
^Select "Descaling" and then "OK".
The display prompts the user through the single steps of the descaling process. Follow the prompts.
If the descaling is started while the machine is still hot, the appliance will cool down for 10 minutes before the descaling begins.
The descaling process cannot be canceled once "OK" is selected. The process now needs to be completed. This is a safety feature to ensure the process will be completed. It is important for best results and the longevity of the machine.
