Bought this unit as a replacement for a GE Profile dishwasher that was 20 years old.  I have only used it about a dozen times, but this dishwasher seems to work well.  However, I generally give my dishes a quick wipe and rinse before putting them in the dishwasher.  I haven't tried it with dried on residue or using the sanitizer setting.  The dishwasher is very quiet.  I only notice it when it starts washing.  Otherwise, I don't know it is running.
