Product review (5 stars): Oh just get the thing already--but shop around.
OVERALL:
Really a fantastic machine. Usually when I hear "efficient" I think 'ineffective'. Not so with this thing. I've had Bosch, GE and Kitchen-aid dishwashers, this one is the best so far---and for far less. It is Consumer Reports choice for 2016--- and it's recommended by both my friend who owns an appliance repair shop, and my friends at Lowe's. Bought this one on sale (normally 599, got it for 399), plugged it in, and ran it through the absolute ringer. ALL of the dishes in the house were dirty, dried on and icky (I really wanted to see how this thing performed and the unit arrived late). I went from the person who soaked and pre-washed EVERYTHING to a person who scrapes off the food and runs that baby---all in that single, trial run. VERY impressed. I used the "sensor" wash cycle and it delivered.. but you may want the 1 hour wash.

NOISE: You'll be checking to see if it's running. I promise. Turn the close captioning off. You won't need it anymore.

CAPACITY: I have a family of five who cooks from scratch...and everyone passes the buck on dishes; Which means I get stuck with them most of the time. What used to take three loads in a day now takes one. Right? Mama Happy Dance... that's me. Adjustable/removable top rack. Deep bottom. Top sprayer points down, sprayer under top rack, sprayer on bottom rack, and the top rack sprayer targets the silverware on the door. Like I said I went from three loads down to one. That's huge.

INSTALLATION:
-You need a 90 degree reverse threaded elbow for the water line, which is not included.
-Whirlpool provides the waste line, but not the water line.
-Whirlpool does not the provide the power cord... snag the one off your old washer or pick up a new one for 15 bucks or so.
-A little duct tape on the insulation at the back end of the washer keeps it from bunching on a tight install.
-Leveled at the factory but that's adjustable.

SHIPPING:
Please note I've seen some sellers list this as 80 lbs in weight. I'm dubious. Lowe's listed it as 55... and really it's so light I had it in out of the van and in my house before my husband got his tools together.

NEGATIVE REVIEWS: I would be dubious of these on various sites. When I go to shop for something I research it like a banshee. I've seen repeat complaints and those complaints change in BRAND, sometimes user name, but not content. This leads me to believe that some competitors are using the review boards with ill intent. While there may be legitimate complaints, of course, I am merely pointing to the things that raised red flags for me, which I compared to the learned recommendations of those whom I know to deal in appliances. I recommend you do the same.

I've seen prices vary widely. Shop around.

COMMON COMPLAINTS: Dry times and smell.
If people would read the owner's manual, they'd be happier.
--You must--I repeat MUST--use rinse aid. If it still isn't working, the "dose" of rinse aid is adjustable and can be changed with a dial in the reservoir. I had to make this adjustment and boom--dry dishes. Let the thing finish its dry cycle... so many do not. Let it air out and cool down for a few minutes before unloading if doing multiple loads.
--You must-- I repeat MUST clean the filter. It's incredibly easy and it keeps your dishwasher from smelling. Think of it this way: you would not leave the strainer in your sink full of gunk for even a minute... why would you do it with your dishwasher?
--Know where the heating element is. Put the plastics on the top---it heats from the bottom. Capice?

Half a cup to a cup of white vinegar on a quick wash will clear out any smells, should you experience them at all.

Questions? Bring em' on. Happy to help. I'm one of those careful shoppers, too.
