On a different note there are arguements from the actual article that say the buildup from crumbs and stuck on food get caught in some filter/tubing, but with a little bit of help from google and elbow grease, these are usually easy to fix on your own. However, I have had this particular dishwasher for 9 years and there have not been any malfunctions despite my lack of pre-rinsing. The one previous to this had issues with the filter that were easy enough to fix once we got the part.
Come on now.
