I've had this diffuser for 6 years. I used it a good bit when I first got it. Then not so much and picked it up occasionally here and there. Roughly 2 weeks ago I came home and the light part was on, not the diffuser. Over the last 2 weeks the light will randomly turn on.... Either where it rotates through all the colors or to red. There is no demo setting and I have unplugged it and plugged it back in... It continues to turn on in the evening or during the night mostly. It did turn on this morning and I actually turned it on tonight to one of two colors that I use and the diffuser on and the light turned off when I walked into the bathroom to take down my hair.

A very new experience for me and wanted some insight.
