Re: Top Rack of Bosch SHU43 is not cleaning the glasses.
I was having the same problem, as well as others. I took out the filter at the bottom and cleaned it thoroughly. I think it was spraying old food remains onto the clean dishes. I would never recommend this dishwasher to anyone. I can't believe it is top rated.

Open door check wash arm position start washer for a minute
Confirm wash arm has rotated
Check for plugged spray tips at either end of wash arm.
Use small tweezers to remove
Check for rack and dishes interfering with arm rotation
Place cup in upper rack with opening up cycle washer.
Confirm that cup quickly fills with water
Not washing check water level in tub mim 1 1/2 inch
Discontinue use of rinse/dry liquid additive.
Confirm rinse/dry additive not leaking from dispenser into tub
Washer detergent contains sparkle additive and too much sparkle/rinses/dry additive will coat dishes
Try alternative wash detergent that contains minimal rinse/dry additive and use without liquid rinse/dry additive.
It will take several wash cycles after the elimination of rinse/dry to purge the oily film from dishes and machine..
If success "joy" is achieved with no additives then cautiously add back wash detergent with additives. Additives are important to facilitate drying and protecting the glassware china from leaching. The leaching process permanently etches the surface of glassware leaving a cloudy appearance.
If you are not using a water softener use a rinse aid such as Jet Dry. This will help to eliminate scum on glassware. Use the solid form of Jet Dry. If you use a water softener you need to decrease the amount of detergent.
You can determine the cause of cloudy glassware by soaking a glass in vinegar for 5 minutes. If the cloudiness is removed it is a hard water deposit and more detergent is likely needed. If the cloudiness is not removed it is a permanent condition known as etching. In this situation, use less detergent and stop pre-washing. In actuality, dishwashing detergent needs a bit of soil to work on, otherwise it will tend to foam up.
There are three typical causes of chronic cloudiness on glassware/dishes.
The incoming water may be too hot. Make sure the water is at or below 140 degrees F.
Test to see if cloudiness is removable by hand cleaning or soaking for 5 minutes in white vinegar. If it is removable, it's due to hard water. Use a good quality detergent, and match the amount of detergent used to the water hardness and use a rinse aid. (Some low quality detergents clean poorly and leave a film.)
Glassware may be etched, due to too much detergent, too high water temperature, or pre-washing. Etching is not reversible, so it's important to correct the problem promptly.
Hopefully these hints will help you to home in on the problem.
Yes. pour two cups of white vinegar into the empty machine. Run your hottest and longest cycle. Always turn on the hot water in the sink and let it run as hot as it will get before you start your machine.
This will clean your machine. Repeat this cleaning as often as necessary. J.
The problem is hard water. Go to www.dishwasherfilter.com. They have a new product out that solves this problem once and for all. It filters the water entering your dishwasher and removes the hard minerals that cause these spots. Very affordable and guaranteed to leave your dishes looking amazing every time.
If the glasses are old or the softener has been allowed to run out of salt a few times the glasses have become etched. When hard water has soap added, the hot water and soap precipitates some of the hardness (limestone - what cement is made from) into particles and the dishwasher shoots this around in the dishwasher and "sandblasts" everything. Once the glass is etched you have to replace it. In future, a. never run out of salt. b. wash good glassware, crystal and fine china by hand.
