We have had our Miele dishwasher serviced numerous times. We use miele detergent and water softner, take apart the drain weekly and clean.
We have used Miele dishwasher cleaner which cleans the inside of the dishwasher. We have tried using a half detergent tablet. We have had the water softener on and then off and then back on. We were advised not to rinse the dishes as the technical said perhaps our dishes were too clean for the machine to work.
We have tried all of the suggestions for extended periods of time to no avail. The machine etches glassware, leaves spots on the glassware and silverware along with soap residue. It cannot clean anything green, like a small piece of lettuce or broccoli. It just get dried on the plate.
It also takes a random about of time to clean using the same cycle -- from 1 hour to 3.5 hours.
And it does not do a very good job of drying the dishes. It is very quiet and it take egg yolk off a dish like nobody's business!
