I wouldn't recommend purchasing a Samsung Dishwasher. Their repair process is VERY poor. Having purchased a dishwasher in August, I have had a service technician at my house 5 times. This brand new dishwasher really never worked. We are now in November and the dishwasher still does not work.
Samsung basically ignores the situation saying that the technician has to declare the appliance unrepairable. Clearly, Samsung has no idea how to be in the appliance business. Can't imagine if this was a fridge or stove.
