Cleaning, care and maintenance
5. Cleaning, care and maintenance
f Have the electrical safety of the appliance and the function of
the safety valve regularly checked by a qualified contractor.
f Have the protective anode checked by a qualified contractor
after the first two years of use. The qualified contractor will
then determine the intervals at which it must be checked
thereafter.
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
Scaling
f 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.
f Check the taps regularly. Limescale deposits at the spouts
can be removed using commercially available descaling
agents.
f Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
