Attention! Do not immerse the appliance or its base in water or other liquids.
8.2 Descaling
In order to remove scale deposited inside the kettle and on the heating element,
prepare a solution of water and vinegar (1 part vinegar to 2 parts water). Pour the
solution into the electric kettle and heat it up, but DO NOT BOIL THE SOLUTION!
Leave the solution in the kettle for about 1 hour, then pour it out. Refill the kettle with
water up to the maximum level and boil the water. Pour the water out and remove
any residue with a damp cloth. If the water at your location leaves lots of scale,
frequent descaling is recommended. Do not perform descaling using chemicals
designed for coffee makers or irons.
Attention! Descaling frequency depends on the quality and type of water used.
Descaling should be performed when you notice that more than ¼ of the heating
element surface is covered with scale.
The appliance contains no parts that could be serviced by the user. Do not attempt
to repair the appliance on your own. Always have the appliance repaired by a
professional.
If the power cord is damaged, it must be replaced by the manufacturer, a service
centre representative or a properly qualified technician.
