Congratulations on your new machine. I've had mine for about a year and love it. What I really like about the machine is I can load it up like crazy. I don't have to worry about not putting plastics on the bottom or stuff melting and burning. Plus, it's in the kitchen which is part of the family room and you can barely hear the thing running. I've posted a link over to That Homesite, The Garden Web, Appliances. It's a pretty good site, lots of infomation to sift through.
Depending on your Bosch model you may have the option for a hotter final rinse. The set up instructions are in the back of your manual. I find this helps with the lighter plastic items. Like those throw away leftover containers. I just keep using mine over and over.
The Bosch dries via a condensation system. So apparently the heavier or more substantial the item the better it will dry. What I do is let the thing finish it's drying cycle. Wait about 1/2 hour then open the door and let steam out and wait until the dishes are cool enough to handle. This usually gets those light plastic items dry.
Our water here in Las Vegas is hard as rocks. In the rinse aid dispenser you can adjust the amount of rinse aid. Try the different settings to see which one works best for you. Again, this also helps with the water sheeting and final drying as well.
You may also notice, depending on your water hardness, detergent use, that the stainless will get marks or calcium looking build up. I just hit mine with some Limeway or CLR and it looks find, hasn't hurt the machine. A little on a sponge then run the machine on a light cycle.
They also don't have a food grinder for those odd bits that get in the machine. At the bottom there is a screen. I check mine about once a month. Twist out the part on the top of the screen. Clean that part, the screen and the very fine metal screen under the large piece. I did find the fine metal screen getting a calcium build up, so I hit it with the CLR and it's back to new.
