Dishwasher noise
I'm not particularly bothered by dishwasher noise. It's a small price to pay for NOT having to wash dishes. Although I can understand those who want it dead quiet. If the kitchen is used as more than a kitchen--which is the case in many homes--noise might a real issue. For me, kitchens are basically mainly used for cooking and nothing else.
The noise argument is something heavily marketed at my nearest Home Depot. I don't know if it's store policy, or just the woman I see working there most times when I wander through. But in any case, if I wander through and look at something, she'll come and we'll talk. And her big argument for buying the model "over there" that's 2, 3 times the cost is how much quieter it is. My attitude is I really don't care about noise, and if I were to buy a 2, 3 times more expensive model it had better be 2, 3 times better as an appliance. Often, I fear, the only thing that goes up is the price and frill features.
I'm not alone in my views. The first time I had this noise talk at Home Depot I was tentatively shopping for my-then roommate, who's dishwasher was acting up, and might or might not be replaced. I heard the noise argument then. When I reported it later to my roommate, I heard something along the lines of: "I'll go with the noisy model, save money, and just turn up the volume on the TV!"
