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 if you use soft water (up to18dH).
- Once every month if you use hard water (more than 18dH).
Contact your local or regional water board for information on the hardness of your tap water. If you use the kettle more than 5 times a day, you may have to descale it more often.
