Mine is only seven years old but it is leaving a gross film on things no matter what I do. I have had multiple service calls. I do everything they say to do and yet it seems the issue is getting worse. I think my model is the 804. It was about 1500.00 dollars seven years ago, the top of the line, and I have to say I have not been thrilled. I am calling the appliance place tomorrow and seeing what other brands they like, Bosch and Asko too, and what they recommend. I hope to have it in by the end of the week because my glasses look nasty and it does not come off when you wash by hand!! I am using the same powder in the same amount as I was told by the Miele repair guy, so I am not sure what gives.
