I have a Miele but have never implemented the water softener feature either.  It sounded way too complicated, and I've never bothered to find out if it's easier done than said.  Water here is fairly hard, but my glassware has remained clear.  I've gotten into the habit of adding maybe a teaspoon of LemiShine to the main wash detergent cup because I'm using tabs of Finish "power ball" or whatever -- the ones with the red M&M.  It doesn't do as good a job as Cascade IMO.  I'm almost done with the Finish tabs and may not have to add LemiShine once I start my new tub of Cascade tabs.

Also, it's been stated here many times that pre-rinsing can cause etching on glassware.  Since I don't generate enough to run the machine every day, I use the rinse & hold cycle to keep odors down.  When I know I'll be running the dishwasher after making a meal or doing some baking, I don't pre-rinse anything.  So far, that routine has worked to keep glassware clear and sparkling.

Another possibility: Could it be etching rather than just cloudiness? The manual for one of my many dishwashers said that etching (which is permanent) can occur with certain kinds of glass if cycles are long and the water is soft. I've always had mechanically softened water, which is super-soft.  Most glassware I've had has eventually gone cloudy and I've just replaced the glasses. It usually starts around the top couple of inches of the glasses, then spreads downward over time.

Am interested to find out if you have luck getting rid of the cloudiness.  I have some heavy restaurant glasses used for iced tea that are gradually going cloudy (or becoming etched).  I have six of them and try to use the same 2 or 3 all the time.  The ones that rarely get used feel much smoother than the etched ones.

Edit: Apologies, Alexander; I was interrupted by a phone call and didn't hit send until a couple of minutes after you'd already posted about etching.

I have a water softener and some of the glasses and bowls we use are cloudy.  Hold them up to the light just right and I can see streaks formed...they are etched.  I once saw some black Arcopal  dishes that were etched like that, but my Corelle does not etch.  My pyrex measuring cups eventually will etch too.  My mother's have done the same thing without a water softener...but I think it took longer with their water than it did for my softened water.  I just replace the glasses when they get too bad...or use plastic.

Your Husband causes this by pre-rinsing, I would use the water softener feature, and then use very little detergent, and then you no longer have to use expensive detergent tablets.

And stop pre-rinsing, I have seen this issue cause some of the more serious disagreements in a relationship.
