My kettle is noisy. What can I do?

All kettles regardless of manufacture will make a noise while boiling. Your kettle will get noisier as it reaches boiling point. Once your kettle has boiled the noise will get lower.
All kettles are designed to boil quickly, thus saving energy.
If your kettle has had a lot of use and shows signs of scale on the element, descaling will help to reduce the noise.
