KitchenAid KDFE454CSS Review

When "good enough" actually isn't.


The KitchenAid KDFE454CSS (MSRP $1,549) really didn’t live up to our expectations. One of the most expensive dishwashers we’ve tested, it offers a large number of cycle choices and extra options for people who like to customize their washes. Unfortunately, it neither looks nor performs like other dishwashers in its price range. There is very little fundamentally wrong with the KDFE454CSS, but when you’re up against the likes of the Bosch SHE8PT55UC, or all the other dishwashers that clean better but cost half as much as this one, “good enough” isn’t going to cut it.

Design & Usability

The plastic panel cheapens the look.

How many bars do you have?

For its price tag, the front of the KDFE454CSS doesn’t look as industrial or professional as you might expect. Part of that has to do with the front-facing control panel, which is gray plastic. While not the prettiest thing, this design does make it easy to show off the KDFE454CSS’s myriad options. There’s a button for each cycle choice and additional wash option, along with a display on the right side. The display will tell you when a cycle is washing, drying, or clean, but in lieu of a digital timer, there’s a bar that slowly depletes as the cycle nears completion. It looks a lot like the signal bar on a cellphone, except you actually want it to be empty.

The interior doesn't look much different from lower-end machines.

The interior is stainless steel, with enough room to fit 11 standardized place settings. The racks are sturdy and stay on their tracks. The cutlery holder has slots to keep your silverware separated, which can also be folded away if you don’t need them. There is a row of collapsible tines on the bottom rack and two more on the top rack. There is also a pair of fold-down cup shelves on the top rack. While these are all neat, there’s nothing groundbreaking here, and certainly nothing that you wouldn’t find on a dishwasher that costs half as much.

At the end of the day, the KDFE454CSS really doesn’t have any faults when it comes to design or usability. Our main gripe is that we paid more, so we expected more. We’ve gotten features like a third rack, chopstick holders, and even an LCD screen from other $1,500 dishwashers, so there are really no excuses here. It can't even spare the expense for a numeric timer; isn't that one of the main reasons for having a forward display?



You have control.

While there aren’t that many ways to adjust the inside of the KDFE454CSS, it has plenty of options when it comes to how it washes dishes. For starters, there are six cycles to choose from: ProWash, Heavy Duty, Normal, Light/China, 1-Hour Wash, and Rinse Only. This covers practically every kind of load, and the ProWash cycle uses soil sensors to determine the right amount of washes and rinses to use in case you’re feeling indecisive.

Better in blue: the KDFE454CSS's high-intensity jet sprays.

If you’re not the “set it and forget it” type, the KDFE454CSS has many ways to customize your wash. The ProScrub option turns on the high-intensity spray jets located in the back of the washtub, for when you need some added power against baked-on stains. If you like turning up the heat, the Hi-Temp Scrub will raise the main wash temperature, Sani Rinse will do the same for the final rinse, and Heat Dry will dry your dishes at the end of a wash. Rounding out the list of features are a Top Rack Only option, 8-Hour Delay, and Control Lock.

Clearly outclassed by other dishwashers

The Normal cycle on the KDFE454CSS gave us high hopes. Even though it took a snooze-inducing two hours and 27 minutes, most of the test stains were removed. Unfortunately, we found that the dishwasher had a small problem with redeposit, which is when food particles from one item get stuck to another during the wash. Other than the long cycle duration, though, we were mostly happy with the Normal cycle.

The dishes actually came out worse...

Given how well the Normal cycle performed, we expected the Heavy Duty cycle to give us perfection. The cycle took three hours and 37 minutes, but the dishes actually came out worse than in the Normal. The minor redeposit issue we experienced with the Normal cycle got amplified during the Heavy Duty cycle. Most of the items on the bottom rack were nearly spotless, but the glasses and mugs we loaded up top got coated with stains from other dishes.

With such long Normal and Heavy Duty cycles, it was a relief that the 1-Hour Wash clocked in at 68 minutes. Not quite an hour, but we can be forgiving. In that short period, the KDFE454CSS did a decent job with the stains. We were pretty satisfied with how well this cycle did, and it can definitely be used to clean light soils in a pinch. The machine’s overall efficiency is pretty good, too. We estimated an annual running cost of $30.71.

Not the best high-end KitchenAid


While our overall evaluation of the KDFE454CSS is positive, it isn’t exactly a glowing review. And for $1,549, we expect it to do more than just glow. With a plastic control panel, long cycle times, and an issue with redeposit, this machine really doesn’t live up to its price. The ProScrub high-intensity jet sprays aren’t even exclusive to this particular dishwasher. In fact, if you want a high-end dishwasher, you don’t even have to look outside the KitchenAid family: the KUDE48FXSS will serve you better, and costs about $300 less.
