We actually have two of these models, the other is now 7 years old at another house we own. We have always had good luck with KA appliances. Even after our bad experience with this one, we likely would have replaced it with another KA. Before this dishwasher we had an older Bosch that didn’t dry well (no heating element). My wife really likes this dishwasher. It cleans and dries well and holds a lot of dishes. We really didn’t want to replace it. Thanks also to everyone on this forum who posted pictures and comments. They were all very helpful. Forgot to mention the most important thing. Before attempting any appliance repair, be sure to get permission from your significant other! Mine couldn’t be happier.

I got a new KitchenAid dishwasher a couple of months ago. My previous dishwasher was also a KitchenAid which only lasted about four years and then the motor died. With the old dishwasher until it stopped working the dishes were always completely dry and there was no moisture whatsoever on the inside walls of the dishwasher. I’ve tried every cycle with this new one and I do extended dry and use rinse aid. andAt the end of the cycle, the dishes are wet and The stainless interior including the door very wet...Plus the dishes are not as clean as they should be

I've had a top-of-the-line KA DW (S model) for over 7 years and no problems at all except the door gasket seal came a little loose about a year ago and I had to reattach it with silicone - no big deal. The DW cleans and dries well and is very quiet. I have no idea about the current models but like any brand I'm sure there are problems with some units.

If you can send the drain down through the floor to a lower level P trap, you can do that. My saying this is not a recommendation "per se" in and of itself, it is just information, which may need further caveats. If the P trap for this DW is in the kitchen, you need to install a high loop. If you know what a high loop is, install that. High loop means to raise a portion of the dishwasher's flexible drain line as high as you can under the sink (e.g. with a piece of bailing wire). This will prevent contaminated water from backing into your dishwasher, unless the backup goes right up to the rim of your sink, in which case, an above-sink air-gap is the only thing that will prevent cross-contamination. The DW drain line branches into the sink drain line below the sink -- regardless of what type your faucet is. I suspect you have a contractor who I would consider a case of borderline fraud. Your contractor must know what a high loop is. He also must know that any dishwasher drain connecting to the kitchen P trap goes first through a high loop or an air gap. In both cases (high loop and air gap), the drain plumbing connection has no relationship to the faucet you chose to install. That is supply plumbing not waste plumbing. Perhaps I have misunderstood your post or you have misunderstood what you thought he said, or some other explanation is possible, et cetera. If not, you have a special case of a contractor saying that the faucet prevented him from raising the dishwasher hose in a high loop and thereby routing its waste water up first before it goes down into the P-trap and the house drain.
