Product review (5 stars): Great dishwasher for the money
UPDATE: 10 months after purchase, the dishwasher stopped working. After waiting two weeks for a Samsung technician, he was unable to fix it, claiming he had the wrong part. To Samsung's credit, they called me the next day and offered to refund me my total purchase price for the appliance, which I accepted. I guess the moral is that this isn't the most reliable dishwasher on the market, but Samsung stood by their product, at least during the warranty period, and made me whole for my purchase.

We researched dishwashers to replace a Bosch dishwasher that had recently gone to dishwasher heaven. We had consistent trouble with the Bosch electronics which kept going bad, so we avoided them even though they are recommended in many reviews as the best, including Consumer Reports. We kept coming back to the Samsung DMT800 and 400 and finally settled on the 400. The biggest difference we could see was that the 800 had a delayed start feature which we knew we'd never use.

This dishwasher gets everything squeaky clean, and we do absolutely no pre-rinsing of our dishes. The Samsung is so quiet that you honestly can't tell that it's running! The ergonomics of the unit are beautiful, with the controls on top of the door so the lines on the front of the dishwasher are only broken by the curved handle and three inconspicuous blue LEDs that track the progress of the wash.

I have only one minor complaint and one warning. The complaint is that there is no indicator to show that the dishwasher is finished and contains clean dishes. Consider this scenario. I turn the dishwasher on before I leave the house. My wife comes home later in the afternoon and has no way of knowing that the wash inside the unit contains clean dishes. Not a biggee, but it would be nice to have something that showed the cycle has completed.

The warning is that this dishwasher is just a tad deeper than other dishwashers. Be careful that you measure accurately and that you have sufficient depth for the Samsung. We needed to take down the sheetrock behind the unit to gain the extra quarter inch we needed.

All in all, it looks like we made a wise choice. I wouldn't recommend Bosch due to our experience with repairs, and after the first 3 weeks, the Samsung seems to have been a wise choice.

UPDATE: We've owned this dishwasher now for a few months and still love it. One correction to the lack of a completion indicator I made above. If you choose "Sanitize", that light will remain on after the cycle to show that the dishes inside are clean. The right-most blue indicator on the front of the door that is actually is programmed to show that the load is completed goes off after 20 minutes. We choose Sanitize for all of our wash loads and it is how we tell whether the dishes inside are clean. The light will go off once the door is opened to empty the dishwasher and not come on again until the next cycle.
