KitchenAid 404 vs. 604 Comparison
Cleaning Performance & Features
Both models deliver a fantastic clean, but the 604 takes it a step further. It includes an advanced clean water wash system that removes food particles from the water between wash cycles, ensuring only clean water cleans your dishes. The 604 also features more specialized cycles, like an Express Wash and a better-optimized pots and pans setting.
The most significant feature difference is the 604's Wi-Fi connectivity. This allows you to monitor cycle progress, start the dishwasher remotely, and receive notifications on your smartphone, a convenience the 404 does not offer. For core cleaning, the 404 is excellent, but the 604's technology provides a more enhanced experience.
Capacity & Flexibility
While both dishwashers include a third rack, which is a big advantage for loading utensils and small items, the 604's FreeFlex™ Third Rack is deeper and more versatile. It accommodates 6-inch glasses, mugs, and bowls, freeing up significant space on the other two racks. The 404's third rack is primarily for flatware and small utensils.
Both models feature adjustable middle racks to make room for taller items, but the 604's premium ball-bearing rails make sliding heavy, fully loaded racks smoother and feel more substantial.
Noise Level
Here, the KitchenAid 604 has a clear edge. At 44 dBA, it's one of the quietest dishwashers you can buy. You'll barely know it's running, which is a major benefit in kitchens that are open to main living areas. The 404 model is still very quiet, usually operating between 44 and 48 dBA, but the 604 is consistently "whisper quiet." If low noise is your absolute top priority, the 604 is the way to go.
Price & Value
There is a considerable price difference of approximately $300-$400 between the two models. The 404 delivers tremendous value, providing premium features like a third rack and a stainless steel tub for a mid-range price. It handles all the essential tasks extremely well. The 604's higher price tag is justified by its near-silent operation, advanced smart features, superior rack flexibility, and enhanced drying system. The "value" of the 604 depends entirely on whether you will actively use and appreciate these premium upgrades.
Which One Should You Choose?
Both are fantastic dishwashers, but they are built for different homes and priorities.
Choose the KitchenAid Dishwasher 404 if:
- You're looking for the best combination of performance and value.
- A quiet dishwasher is important, but absolute silence is not a must-have.
- You want essential high-end features like a third rack without paying for smart technology you might not use.
- You have a small- to medium-sized household with standard dishwashing needs.
Choose the KitchenAid Dishwasher 604 if:
- Minimizing noise is your top priority, especially in an open-concept kitchen.
- You have a large family or frequently entertain and need maximum loading flexibility and capacity.
- You love smart home technology and want to control and monitor your dishwasher from your phone.
- You are willing to invest more for the most advanced features, best drying performance, and a more refined user experience.
Frequently Asked Questions
What's the main difference between the KitchenAid 404 and 604?
The main differences are in features, noise, and price. The 604 is quieter (~44 dBA vs. 44-48 dBA), has Wi-Fi connectivity for smart control, a more flexible third rack (FreeFlex™), and includes premium cycles and drying systems. The 404 is more affordable and focuses on delivering excellent core cleaning performance with essential features.
Is the KitchenAid 604 worth the extra money?
Whether it's worth it depends on your lifestyle. If you have an open-concept living space where noise is a major concern, or if you'll use the smart features and extra capacity regularly, then the upgrade can be easily justified. If you just need a great, reliable dishwasher, the 404 offers better value.
Do both models have a third rack?
Yes, both dishwashers have a third rack. However, the 604's FreeFlex™ Third Rack is more spacious and can hold deeper items like mugs and small bowls, providing more loading flexibility than the utensil-focused third rack on the 404.
Does a stainless steel tub really matter?
Yes. Both models feature stainless steel tubs, which offer better drying performance by retaining heat, resist stains and odors more effectively than plastic tubs, and are more durable over the long term.
How quiet are these dishwashers in the real world?
A decibel rating in the mid-40s is very quiet. The 604 at 44 dBA is about the sound of a library - you will likely hear more water sounds than the motor itself. The 404 is also quiet, comparable to a soft conversation, and is a big improvement over older dishwashers.
Are KitchenAid dishwashers reliable?
KitchenAid has a strong reputation for making durable and reliable appliances, including their dishwashers. Both models are built with quality components and are considered a solid investment for a kitchen.
Are these dishwashers ENERGY STAR certified?
Yes, both the KitchenAid 404 and 604 series are typically ENERGY STAR certified, meaning they meet strict standards for energy and water efficiency, which can help lower your utility bills.
What is the benefit of the Wi-Fi feature on the 604 model?
The Wi-Fi feature lets you connect the dishwasher to your home network and control it with a smartphone app. You can start a load remotely, check how much time is left in a cycle, get notifications when it's done, and even download specialty cycles.
