We have a Bosch 800 series with the third rack. It also has a red light. I wish the light displayed numbers with time remaining, but maybe in the future. Ours doesn't have wifi or similar features, which I think is ridiculous for a small house. Our previous one lasted for 12 years and had an external display, and still worked when we replaced it but it was a bit noisy after a pump replacement.
The new one is so quiet you can barely hear it. The only loud noise is when the dirty water goes into the garbage disposal. You should load it with the plates scraped but not rinsed, it cleans better that way. You have to clean the filter after every cycle or two. Ours get some yellow goo in the filter trap from congealed/suspended fats, and there is usually some debris as well.
The best features are the more efficient rack, the ability to put plastic items anywhere, and the small upper rack for utensils. I also like the delay timer so you can use cheaper electricity if you have time of day service. Even if you don't most of our power comes from nuclear at night so less pollution. You will be very happy with your Bosch, no matter which model you bought. They all clean well.
