Decalcifying of The Coffeemaker
The coffeemaker must be decalcified regularly. The frequency depends on the
hardness of your water and how often you use the coffeemaker.
Recognizable indications that descaling is necessary are:
• increased noise during boiling
• longer preparation time.
• if usage is frequent, descaling should be carried out as follows:
with soft water once a year
with medium hard water every quarter year
with hard water once a month. In doubt regarding the water hardness in your
area, you may call your local water department. For ecological and health
reasons, we recommend the exclusive use of biological materials such as citric
acid, which can be obtained from drugstores. Dissolve 2 tablespoonfuls of citric
acid in 1/2 quart water and pour into the water container. Run this through 2 or
3 time as if making coffee, but using no ground coffee. The hot descaling
solution must be allowed to cool down before being poured into the water
container. Finally do the same twice using clear water.
