Cleaning
Always remove the plug from the mains supply before
cleaning the machine!
The exterior of the machine should be cleaned, if necessary,
with a slightly damp cloth without additives.
Wash the lid and the egg tray in a normal sink.
Decalcification
The decalcification intervals depend on the hardness of the
water and the frequency of use.
If the machine switches off before the water boils, it probably
needs to be decalcified.
Do not use vinegar, but a normal citric acid-based decalcifier.
Follow the manufacturers' instructions!
