KitchenAid is one of the most recognizable dishwasher brands in the world. Offering state-of-the-art cleaning features, spacious racks, and reasonable prices, it’s no surprise why many households use their dishwashers.
Finding the right KitchenAid dishwasher can be pretty overwhelming because of the wide array of options available. But not to worry, that’s what we’re here for.
Below, we’ll take a closer look at KitchenAid KDTM404KPS and KDTM604KPS dishwashers. We’ll go over their similarities and differences so you can find the right choice for you.

KitchenAid’s KDTM404KPS is an entry-level dishwasher with an affordable price and cutting-edge features—most of which you’ll find on the 604KPS models. It is equipped with an advanced clean water wash system, a ProWash cycle, and a FreeFlex rack.
The 404 model is a step up from the 304 models in terms of space and loading opportunities. Featuring a deep, angled third rack, it can fit up to 6” saucers, mugs, and glasses, unlike the standard rack.
This FreeFlex third rack even has rotating wash jets, which ensures that every item on the rack gets thoroughly washed and rinsed every cycle.
We like that all the racks offer ample flexibility, allowing you to accommodate a variety of dishes in a single load. Thanks to its cutting-edge wash system, you can also wash the greasiest pots with the most delicate glassware at the same time.
The ProWash cycle enables the dishwasher to detect the soil level of your dishes. Then, it automatically adjusts the wash time and temperature to give your dishes a thorough clean without wasting too much water and energy.
Combined with an advanced microfiltration system, the dishwasher can filter the food residue from the dishes, preventing them from getting redistributed. This ensures fresh, sparkling clean dishes after every wash.
The 404KPS has a condenser drying system, which uses hot water and heated air to dry the dishes. Although it can fully dry glasses, ceramics, and metals, it does struggle to get plastic items bone dry.
On the bright side, there is a significant difference in performance if you use Rinse Aid and the Extended Heat Dry Option for hard-to-dry plastics.
KitchenAid KDTM604KPS
Brand | KitchenAid |
Model | KDTM604KPS |
Dimensions | 23 ⅞” x 33 ⅝” x 26 ¾” |
Installation Type | Built-In |
Place Settings | 16 |
Noise Level | 44 dBA |
Number of Racks | 3 |
Wash Programs | Express Wash, Normal, ProWash™, Rinse, Tough |
Features | Fan-Enabled Pro-Dry System, PrintShield Finish, ProWash Cycle, FreeFlex Third Rack, SatinGlide Rails, Advanced Clean Water Wash System |
Tub Material | Stainless Steel |
Pros
- Advanced microfiltration prevents the redistribution of food residue
- Smart sensing capabilities
- Reliable drying performance
Cons
- No WiFi connectivity
The KDTM604KPS dishwashers are equipped with the best cleaning and drying features that KitchenAid has to offer. Combined with the FreeFlex Third Rack, it offers a lot of space and flexibility, allowing you to fit a wide range of items in a single load.
An advanced microfiltration system ensures the removal of food residue from the dishes, preventing them from getting redistributed throughout the cycle. This very system also circulates clean water across the three racks.
What we like about this wash system is that it enables you to wash the dirtiest cookware with the most delicate glassware. If you have a large household, it saves you a lot of time and energy by washing everything in a single load.
Additionally, it has smart sensing capabilities, which automatically adjust the wash cycles based on the soil level of your dishes. It makes dishwashing quick, easy, and hassle-free for every household.
Aside from its advanced cleaning capabilities, the KDTM604KPS dishwashers are equipped with KitchenAid’s ProDrying system. This uses a heating element and a fan to thoroughly dry your dishes, including plastic items.
The KDTM604KPS dishwashers offer great value for its price even though it lacks WiFi connectivity. Most modern dishwashers, even entry-level models, have such a feature that enables you to remotely monitor and control cycles.
Still, we don’t think it’s a dealbreaker. Even though it lacks remote controls, you can take advantage of its 1-24-hour Delay Start feature to delay the start time of a wash cycle and run the dishwasher during off-peak hours.
Overall, KitchenAid’s KDTM604KPS is a solid choice for large households looking for a reasonably-priced dishwasher with reliable cleaning and drying power.

Differences
- Drying system – One of the biggest differences between the KitchenAid 404 and 604 models is the drying system. The former uses a combination of hot air and water to dry the dishes, while the latter uses a heating element and a fan.
The 604 dishwashers have a superior drying performance because of their drying system. Compared to 404 models, they can dry plastic items better even without extending the drying cycle.
- Delay times – These two models also differ when it comes to the Delay Start, which is the feature that allows you to start a dishwasher cycle at a later time.
On the 404 models, you can set the delay start feature at 2, 4, and 8-hour intervals. The 604 models, on the other hand, can be set to 1 to 24-hour increments.

In terms of cleaning performance, the more affordable KitchenAid KDTM404KPS is up to par with the KDTM604KPS models. Since they have the same cutting-edge cleaning system, they can deliver consistent results.
The KDTM604KPS, however, is far superior in terms of drying. Since it has a fan-enabled ProDry system, it is capable of drying thick plastic items while the KDTM404KPS condensation drying system struggles to get them bone dry.
Overall, the KDTM604KPS is better. Although slightly more expensive, we think it’s worth the upgrade because of its reliable drying power.
