5. Cleaning, care and maintenance
f Have the electrical safety of the appliance regularly checked
by an electrician.
Scaling
f Almost every type of water will deposit lime at high tempera-
tures. Limescale will settle inside the appliance and affect its
function and service life. The heating elements must there-
fore be descaled from time to time. A qualified contractor
who is aware of 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.
f Regularly activate the safety valve to prevent it from becom-
ing blocked e.g. by limescale deposits.
