Are you perhaps using tabs? Dishwashers need detergent in the rinse cycle, otherwise they don't rinse well, and tabs don't let you do that. I've had friends who have always pre-rinsed because of wrong dishwasher use. Once they switched to powder and put some in the rinse cycle their dishes don't need pre-rinsing.

Thank you, I will definitely watch this. We have tried pre-wash detergent, tabs, liquid soap, powder detergents, in various combinations.

There may be something unusual wrong with our dishwasher. Although we clean its filter regularly, sometimes a kind of brown slime forms along the walls and around the filter, and I have to give it a deeper cleaning. Bosch had no idea what this was! I'm curious if anyone else has experienced something like that.

That almost sounds like your washer isnt using hot water. It would explain the poor cleaning performance and the weird growth in the filter.

whoa. sounds like your drainage might be at fault. i have never heard of anything like this. I'm not a plumber, or anything related, but dishwashers should not have slime and should not need cleaning. yikes.
