5. Cleaning, care and maintenance
Have the electrical safety of the appliance and the function
of the safety assembly regularly checked by a qualified
contractor.
The signal anode must be replaced by the qualified contrac-
tor as soon as the SERVICE ANODE indicator illuminates (see
chapter "Maintenance/ Replacing the signal anode").
Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Scaling
Almost every type of water will deposit lime at high temper-
atures. This settles inside the appliance and affects both the
performance and service life. The heating elements must
therefore be descaled from time to time. A qualified contrac-
tor who knows the local water quality will tell you when the
next service is due.
Check the taps/valves regularly. You can remove limescale
deposits at the spouts using commercially available descaling
agents.
Regularly activate the safety valve to prevent it from becom-
ing blocked, e.g. by limescale deposits.
