Product review (1 stars): Don't waste your time.
Don't waste your time.  The Samsung DMT400RHB is the worst dishwasher ever.  This dishwasher never cleaned our dishes as stated in specifications.  It always took 2  to 3 hours to complete a cycle. We tried all the manufacturer recommendations, used the proper detergents and rinse agent and basically washed our dishes before putting them in the dishwasher. The drying cycle is worthless. Dishes always came out wet after any cycle we used.  Don't even think about putting a dish in with food on it.  Any food particles just got cycled through and were left on the dishes.  In just over a year (just out of warranty), the dishwasher's "overwater" sensor broke and wouldn't finish a load.  We had this repaired by a reputable repairman to the tune of $170.00 parts and labor.  This fix worked for about three months and we started getting the same problem all over again.  Needless to say we got rid of this dishwasher.  I just want to let others know that the Samsung DMT400RHB is a piece of junk and Samsung "Customer Service" is non existent.  So save yourself some grief and buy another brand of dishwasher.
