Whirlpool DU1055XTS 24 in. Built-in Dishwasher

We purchased Whirlpool appliances for our new home. The fridge and stove are great, but this particular dishwasher is horrible!!
It is so loud that we can't sit at our kitchen table and talk while it's running ,it can be heard over top of our vacuum cleaner, and as for setting the delay to come on during the night, forget it,the fact that it starts and stops many, many times during a cycle keeps us awake for hours. Did I say hours, it takes over 3 hours to do a normal load I cannot imagine how long it will take to do a heavy load. I have contacted Whirlpool, but don't really expect much, so if they won't replace it, then they will be coming out monthly to do service calls until they do, do something.
