I met you lovely wife several years back to pick up something I bought, and she was a good bit out of your league if I remember correctly...Yep
My wife wanted the “super quiet” Bosch dishwasher.
I love my wife.
I bought her one……
And then I had to go buy all the “hidden cost” parts to install it.
You live. You learn.
P.S. I love my wife. But there are times when I wish my wife would be as quiet as that damn dishwasher.
We bought Kitchen Aid dishwasher 2-3 years ago and it's the quietest dishwasher I've never heard. The only way we hear anything is if someone puts a bowl lid or something similar on a middle shelf. I've installed close to 50 and unless the sales person talks you into an install kit, you'll have to reuse the old or go back and buy a set. I Always buy a new supply line that is designed to "shunt" the water flow if it detects a leak.
