I have a Sunpentown SP 3000 hot water pot. It heats and holds 3 liters of water fairly quickly. I put only filtered water in it; we have a reverse osmosis system. I wouldn't think of putting our "softened" hard water in it!
Recently I noticed tiny little bits of white stuff floating on the surface of the water. It's the consistency of tooth paste. I don't wash the pot with soapy water; I just let it air dry. What could this material be? Do I need to worry? The operation of the appliance isn't affected at all.
I do tend to leave the pot on for many hours, sometimes overnight if I have to make a quick business of my breakfast in the morning.
Here's the pot:
