, The light rings around the KEEP WARM button and the on/off button go on to indicate that
the keep-warm function is activated (Fig. 15).

, After 30 minutes, you hear an audible signal and the kettle switches off automatically.
Note: You can always stop the keep-warm process at any time. To do so, press the KEEP WARM button or
the on/off button or remove the kettle from the base.
Note: If you remove the kettle from the base, the set keep-warm temperature is lost.
Note: If the set keep-warm temperature is 100°C, the kettle keeps the water at a temperature between
90°C and 100°C to avoid excessive steam development. If the selected keep-warm temperature is 90°C,
80°C or 40°C (or 90°C, 80°C or 70°C for the beige-wood brown model), the kettle keeps the water at a
temperature between 5°C below and 5°C above the selected temperature.
cleaning and descaling
Always unplug the base before you clean it
Always remove the kettle from the base before you clean the kettle.
Never immerse the kettle or its base in water.
Do not use abrasive cleaning agents, scourers etc. to clean the kettle.
cleaning the kettle and the base
1 Clean the outside of the kettle and the base with a soft cloth moistened with warm water
and some mild cleaning agent.
Do not let the moist cloth come into contact with the cord, the plug and the connector of the base.
Cleaning the filter
Scale is not harmful to your health but it may give your drink a powdery taste. The anti-scale filter
prevents scale particles from ending up in your drink.
Clean the Triple action anti-scale filter regularly in the following way:
1 Take the entire filter out of the kettle (Fig. 16).
2 Slide the basket off the filter and take the stainless steel mesh out of the basket.
3 To clean the mesh, squeeze and rotate it under a running tap.
4 Gently clean the filter with a soft nylon brush.
5 Put the mesh back into the filter basket and slide the basket onto the filter again. Then slide
the filter back into the kettle.
Note: You can also clean the filter in two other ways. Leave the filter in the kettle when you descale the
kettle (see section ‘Descaling the kettle’) or remove it from the kettle and clean it in the dishwasher.
Descaling the kettle
Regular descaling prolongs the life of the kettle.
In case of normal use (up to 5 times a day), the following descaling frequency is recommended:
- Once every 3 months for soft water areas (up to 18dH).
- Once every month for hard water areas (more than 18dH).
1 Fill the kettle with white vinegar (8% acetic acid) up to three-quarters of the maximum level.
2 Add water to the maximum level.
3 Bring the water to boil.
