OPERATION
Cleaning, care and maintenance
4.
Cleaning, care and maintenance
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
f Check the taps regularly. Limescale deposits at the tap out-
lets 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.
f Have the protective anode checked by a qualified contractor
after the first 2 years of operation. The qualified contractor
will then determine the intervals at which it must be checked
thereafter.
Almost every type of water will deposit limescale at high temper-
atures. This settles inside the appliance and affects both the per-
formance and service life. The heating element should therefore
be descaled if necessary. A qualified contractor who is aware of
the local water quality will tell you when the next descaling is due.
