DISHWASHER ODORS
If you’re noticing food odors in your dishwasher, check for food soils stuck on the bottom of the tub and in hard-to-reach places. Then run a cycle with affresh® Dishwasher Cleaner or 2 cups of white vinegar. For a vinegar rinse, put vinegar in an upright glass on the bottom rack, then run a normal cycle with the dry option turned off.

The smell could also be coming from the garbage disposal, if the dishwasher drain is connected to it. Run the disposal to clean out any debris. Then clean the dishwasher and disposal with a fresh.
DISHES NOT GETTING CLEAN
Black or gray marks
These marks are created when aluminum items rub against other dishes. Make sure silverware is loaded so it does not touch other dishes. Throw-away aluminum items should not be loaded into the dishwasher at all but hand washed instead. Aluminum marks can be removed with a mild abrasive cleaner.

Brown stains
These are likely the result of water with a high level of iron. You can remove these stains from a fresh load of dishes by re-washing them with affreshaffresh® dishwasher cleaner in the covered section of the detergent dispenser instead of detergent. Follow with a normal wash cycle with detergent.

If the brown stains are a constant issue, you may want to consider the installation of an iron removal unit.
