Why doesn't the clean light come on at end of cycle of my Bosch dishwasher?
It's an energy-saving feature. This is one of the ways the DW gets a good Energy Star rating. Having a light come on and stay on would use electricity. Depending on the model, it will tell you when it is working (red light, projected graphic, etc.), and when it no longer says it is working, then it's done. No light necessary.
