4. Cleaning, care and maintenance
f Have the function of the safety assembly and electrical safety
of the fitted accessories regularly checked by a qualified
contractor.
f Never use abrasive or corrosive cleaning agents. A damp
cloth is sufficient for cleaning the appliance.
4.1 Signal anode consumption indicator
Material losses

tor and if necessary replaced.

4.2 Scaling
f Almost every type of water deposits limescale at high tem-
peratures. This settles inside the appliance and affects both
the performance and service life. If a flanged immersion
heater is installed, the heating elements must be descaled
from time to time. A heating contractor who knows the local
water quality will tell you when the next service is due.
f Check the taps/valves regularly. You can remove limescale
deposits at the tap outlets using commercially available des-
caling agents.
5. Troubleshooting
Telephone your contractor.
