The Whirlpool WDF520PADM is well-rated, including excellent washing, and recommended by Consumer Reports. It does have the sani rinse feature. (I'm not a Costco member so I cannot see its price but it's very well-priced at $398 at Home Depot.) You don't have to spend the big bucks for a good dishwasher.

My friends Kitchenaid leaked and damaged his wood floor. Of course out of the 1 year joke warranty. Insurance paid for the new floor and he got another Kitchenaid. . .Then my friends Kitchenaid leaked and damaged his wood floor. Whirlpool is the parent company that began the one year warranty on all their appliances. A warranty that in no way mirrors the ordinary expectations customers have for an appliance. . . .In no instance will I support a company with those as a core part of their commercial goals.

"Whirlpool is the parent company that began the one year warranty on all their appliances."

Well, then you can buy the Ikea RENLIG or BETRODD dishwasher manufactured by Whirlpool with 5-year parts and labor warranties.

We have a KitchenAid (in the inlaw unit) and a Miele. The Miele works flawlessly on every single wash (even when I forgot to add detergent!) and hasn't ever given me any trouble in the many years that we have owned it.

The KitchenAid breaks regularly. The fix only requires a $20 part. But if I don't get and install that part every so often, the top basket comes crashing down. It's inefficiently organized and as a result holds much less. It doesn't have the super useful third-level cutlery tray that I get with the Miele. It doesn't have a built-in water softener. About every other wash, it has several items that I still need to wash by hand. It's quite aggravating. But yes, it's cheaper, and Consumer Reports likes it better. What a joke.

Having said that, the inlaw unit gets used much more rarely. The KitchenAid made sense there. But for a washer that is used on a daily basis, get something reliable that actually washes. Bosch and Miele are both trusted brands for dishwashers. There is a reason why they keep getting recommended when this question comes up.

no idea.
