I just purchased this dishwasher and wish I would have kept the one I had that was 15 years old.  This dishwasher takes several hours to wash a load.  Also, dishes come out extremely wet, not to mention, what about mold growing inside if everything remains wet.  My older washer ran a complete load in 48 minutes, plus dishes came out very dry and hot.  No water was left inside my older dishwasher.
