The brand raves about how quiet the dishwasher will be. This is rated at 43Db. Standing across the room my DB range is 46-49. I suppose when it is averaged with the dry cycle, they can legally state 43Db. But do not expect whisper quiet.  The dishes  come out beautifully clean. The steam at the end of the dry cycle doesn't seem to be so hot to worry about the impact on the finish of surrounding cabinetry. The red light just tells me the dry cycle hasn't finished. It certainly isn't needed for the wash cycle... at all.
