Descale your kettle regularly!
Descale your kettle from time to time to prolong its life and to safe energy. Limescale deposits in water will build up inside the kettle and stick to the internal surfaces. This will reduce the efficiency of the kettle, damage the seals, interfere with the quiet boil function and in extreme cases, void your warranty.
Most supermarkets sell de-scaling tablets, powders or liquids. These are inexpensive, easy to use and perfect for ensuring your kettle provides many years of faithful service. For cleaning external surfaces use a soft cloth moistened with a mild detergent solution. Do not use abrasive or strong chemical cleaners and always ensure the kettle is unplugged from the main supply and completely cool before cleaning.
