Kay, I just bought the 500 version of this washer, the first of the month, and the matching dryer, as well. It replaced my Frigidaire front loader that died. I loved that machine, but it had to have so many repairs, it just was not worth fixing any more.
For what it's worth, here's my two cents on the Bosch, although I don't know the difference between the 100 and the 500. (I'm copying the list, for others who might be interested.)
The machine is very well made, and it offers a bunch of options that I like very much, including cold/warm/hot for both permanent press and cotton settings. It also has an "extra"sanitary cycle, plus a "kids" cycle that I may use once or twice, but I use cold for everything but linens and underwear, which is maybe one load a week. In addition to a lot of other cycles I'll rarely use, it has a "wool" cycle that is perfect for gently washing wool. I washed a load (10) of wool sweaters last week, using Eucalan, and it was a worry-free version of what I used to do with the old washer. It very gently tumbles the load just a couple of times, enough to wet the wool, lets it soak for 15 minutes or so, and then very gently spins the water out. Uses very little water. My sweaters looked very good, and I was pleased with the results. This cycle alone will save a fortune at the cleaners. I also used the "refresh" cycle once, when I just wanted to quickly wash something small; it takes about 25 minutes. That's another cool thing about this electronic washer--there is a display that shows roughly how much time is left in the cycle. It's not accurate to the second, but it's good to know about how much time is left.
One of the problems with my old washer was that the front door was easy to unseat. The Bosch door is canted backwards, and the handle is at the top, so it is not as fragile. Also, because the doorway is slanted, and because it uses so little water (5-15 gallons per load), you can open the door in the middle of a cycle without spilling water on the floor. I really like that feature. It holds a ton of clothes, too.
The wash results are good; it is just about the same as the old one, which I was very happy with. It does not seem to spin as much water out, though, which is good and bad. Good, because it's more gentle on the clothes; bad, because it may take slightly longer to dry. But it's just barely noticeable, so it's not the worst thing that can happen.
The other thing I don't care for so much, although I'm getting used to it, is the signal that lets you know the load/cycle is finished. It's LOUD, and insistent. My laundry room is between the kitchen and the family room, so it's not as necessary for me, but it does force me to get up and put the load in the dryer! In the past, I've forgotten. There is a way to turn it off, but it looks as though you have to make that decision every time you use it (I could be wrong; I'm famous for not reading manuals), but I've decided to let it boss me around for now.
The matching dryer replaces our 26-year old GE dryer that took me through raising two babies, bless its hard-working heart. But the Bosch is a dream. Lots of choices for drying cycles, a moisture sensor, and again, a signal. And a light inside! I've never had that, and I'm enjoying being able to see when I'm taking stuff out. I'm betting that my kids will no longer leave odds and ends here when they've done laundry on visits home.
Both the washer and the dryer continue to tumble the clothes until you open the door, which is a big improvement over sitting there getting wrinkled.
If anyone has more questions, let me know.
