Troubleshooting - There is white or glittering flakes floating in the hot water and adhered to the inner container.

Any milky-white gritty surface (caused by calcium), White or glittering floating material (crystals of minerals), Discoloration in the finish like dark brown, gray, or green areas (metallic ion made on the fluororesin covering) are not discoloration or corrosion of the inner container itself, nor are they flakes from the fluororesin covering. While you are using this unit, minerals contained in the water (like calcium) can get stuck on the inner container or on the mesh filter. This is called "scale", It is not flakes of fluororesin and it is harmless. Water with a large content of minerals in it such as mineral water or ionized water, is more likely to cause a scale or white layer in the hot water. Clean the inner container with a wet soft sponge.


Note:

If the “scale” still remains, clean with citric acid.
