Cleaning

Almost every type of water will deposit limescale at high tem-
peratures. Limescale will settle inside the appliance and affect
its function and service life. The heating elements must there-
fore be descaled if necessary. A qualified contractor who is
aware of the local water quality will tell you when the next de-
scaling is due.
u A damp cloth is sufficient for cleaning the appliance. Never
use abrasive or corrosive cleaning agents.
u Check the tap regularly. You can remove limescale deposits
at the outlet using commercially available descaling agents.
