Product review (1 stars): Indeed it is very quiet
Well, yes, this is the quietest dishwasher we have ever owned.  The way they apparently got it so quiet is by eliminating the noisy operations that lead to clean dishes.  Many of the dishes in a load will come out clean but many in random and every changing pockets will not -- regardless of load density or method of stacking.  The rack configurations are weird and do not match any of our normal dishes.  As a result about 10% of our mugs and plates have now got chips at the rims from bumping together. Oh and did I mention that the dishes are not dry at the end of the cycle?  The dishwasher is like a dysfunctional member of the household who has forced us all to change our behavior to enable it.  We pre wash dishes to the point where it is hardly useful to put them in the dishwasher at all.  We don't even think of putting certain shapes and sizes of dishes in and instead wash them by hand.  At the end of the cycle we leave the door open for 15 minutes to let the plates dry.  It is infuriating, especially considering how much we paid for the darn thing.  Although it is only 3 years old we are getting ready to junk it and get something else.
