Why does my kettle leave white flakes in the water?

White flakes in boiled water are usually caused by limescale, especially if the kettle is used with hard water. This is common in kettles with concealed or immersed heating elements, and the flakes are often a sign that the inside needs descaling rather than that the kettle is broken.

1. Unplug the kettle and let it cool fully. Expected result: it is safe to inspect the inside.
2. Look inside the kettle and around the heating area for white deposits. Expected result: visible scale is present if the flakes are limescale.
3. Descale the kettle using the cleaning method recommended in the product instructions. Expected result: the deposits reduce and the flakes become less frequent.
4. Rinse the kettle thoroughly and boil one fresh batch of water before use. Expected result: no loose particles remain in the cup.
5. If flakes still appear after descaling, or if the inside surface looks damaged, stop using the kettle and contact the retailer or store where it was purchased.

Do not drink water from a kettle that has loose internal material, peeling surfaces or any sign of damage around the heating area. If you are unsure whether the flakes are scale or something else, stop using the product and seek advice from the retailer.
