Ever wonder what it would be like to run your dishwasher and not have to compete with the distracting noise? The Samsung's dishwashers make it possible. A 6-layer insulation system reduces the sound level so that it?s super quiet. Need more evidence? Samsung also covered the entire base of the machine, to further decrease motor noise. And with options like a half load wash and delay start, you?ll enjoy every feature the DMR77LHS has to offer. Special features include: Sanitary, Quick Wash, Half Load, Normal, Heavy Wash, Auto Sensor, Concealed Heating Element, Triple Filter System, Start Timer Delay, and Child Security.
