Here's what I don't understand
Don't the manufacturer's TEST these things with "really" nasty dishes (baked on) etc...to make sure they work well before starting production knowing that people are going to pay a LOT of money for these, knowing their reputation is on the line etc? I have a Whirlpool DU1055xptq that is 4.5 years old.
I had never had any experience with "quiet" dishwashers. Anywhere I have ever lived the dishwasher was pretty basic, not necessarily ancient, but still basic and pretty loud. When I first used the WP I couldn't believe how quiet it was based on what I was used to. I didn't hear the intense water sloshing that I was used to. The first load I was disappointed with the results. I discovered if I use Cascade Complete powder that the NASTIEST dishes come out clean in it. If I use ANY other detergent, I can see the difference.
With the older dishwashers, it didn't matter which brand I used. EVERYTHING usually came out clean. With this one, I HAVE to use CASCADE COMPLETE! Oh, and my rinse aid dispenser developed a leak so I can't use rinse aid.
