DE-SCALING THE KETTLE

For de-scaling you may use white vinegar.
WARNING:
avoid injuries to your respiratory tracts. Always ensure good ventilation during de-
scaling.
1. Fill the kettle with ½ litre of vinegar and add approx. 1 litre water up to the
"Water MAX" filling level. Close the kettle using one of the lid sets. Simply leave
the kettle stand for at least 1 hour.
2. To assist de-scaling with large amounts of scale: You may warm up the solution
to the lowest possible temperature (50°C, "Custom" program), and cancel ope-
ration by holding the "Start/Stop" button pressed for 3 seconds as soon as the
solution is heated and the signal sounds. For this ensure good ventilation, and
keep the kettle closed via a lid set. Leave the solution cool down within the kettle
for at least 1 hour.
3. Empty the kettle and rinse the interior of the kettle with clear tap water.
4. Then fill the kettle to the "Water MAX" filling level (1.5 litres) with clear tap water
and bring the water to the boil ("Hot water" program). Thereafter, discard the
water and rinse the kettle again.
5. Repeat the complete procedure, if there is still any scale left.
