  The Samsung DMT400RHW/XAA is a fairly large-capacity dishwasher that should be relatively quiet. It has touch controls hidden on the top door edge; an adjustable upper rack with foldable tines to create more space for larger or odd-shaped items; two cup clips to secure light items; and a digital leak detector that shuts the machine off with a leak of 1.5 ounces or more.

What People Are Saying:

User reviews are mixed, but slightly more users like the Samsung DMT400RHW/XAA dishwasher than dislike it, with about 60%-70% recommending it. Positive reviews say it's quiet and washes well, but even those who recommend it complain that it doesn't dry well, the sensor setting doesn't always get dishes clean and that fitting dishes in the racks can be awkward. Negative reviews agree that its quiet but say it's unreliable, doesn't clean well, has poorly designed dish racks and that debris accumulates under the door and creates a bad odor.
