Descaling
The hardness of the water will lead to a scaling up of the appliance over time .
Limescale impairs the functionality of the appliance, reduces the quality of the
tea and increases energy consumption .
NOTE
►
Ask your local water utility for information about the hardness of the water .
If your water is very hard, descaling is necessary sooner, with softer water
later . Use a descaler suitable for household device and follow the usage
instructions .
1) Use a standard commercial lemon-based descaler . Always follow the in-
structions on the packaging of the descaler .
2) Insert the brewing system into the jug
3) Add the descaler solution to the jug
MAX marking and never less than the MIN marking .
4) Wait 10 minutes and then switch the appliance on .
5) Allow the solution to boil and then wait until it has run through the brewing
system .
6) If necessary, repeat the process . You can re-user the descaler solution but
you will have to allow it to cool down first .
7) Once the limescale has been loosened, boil clear water and run it through
the system . Repeat around 2–3 times .
8) Afterwards, clean the jug
