A: When I 1st got it, I had trouble too. I think what you might be experiencing has to do with the reservoir top. If you don't put it on properly it's not going to spring into place. But the bubble where the light is will always fit together you just have to make sure you take your time to put it on there. But I'd be willing to bed has to do with the top on the actual vessel.And then you have to make sure you put it in the triangular shape the bottom and the top. It is a little tough at 1st
A: The red light means the unit is off or empty of water (automatic shutoff). The other three colors indicate the vapor output levels. The blue is the highest output, green is the mid level output and the yellow is the lowest vapor output. Your room size where the unit is operating will also determine the amount of humidity that the vapor can reasonably cover.
A: Those colors indicate the mist output settings. The first one is high, then medium and then low setting. Red is off, no mist at all.
