KitchenAid Dishwasher 304 vs. 404 Comparison
Cleaning Performance & Cycles
The biggest distinction between the KitchenAid 304 and 404 lies in their cleaning technology. Both models utilize the ProWash system, but the 404's version features more advanced sensors that make more precise micro-adjustments to water use and cycle time based on soil levels, potentially resulting in better cleaning on very tough loads.
The most significant upgrade, however, is the 404's exclusive bottle wash cycle. This feature uses specially designed, high-pressure jets to clean the insides of tall or narrow items like water bottles, baby bottles, and vases - items that often stump standard dishwashers. If your household uses these items frequently, this feature alone could justify choosing the 404.
Design & Controls
Both dishwashers present a clean, minimalist aesthetic with fully integrated panels and hidden top controls that allow them to disappear into your cabinetry. They are nearly identical from the outside, sharing a stainless steel finish. However, the 404 model features small but noticeable refinements to its digital display and control panel. The interface is slightly more modern and intuitive, which enhances the high-end user experience.
Interior & Loading Flexibility
When it comes to loading capacity and flexibility, the two models are on equal footing. Both feature a spacious three-rack system that includes a dedicated third-level rack for utensils, silverware, and other small items, freeing up valuable space on the lower racks. They also have an adjustable middle rack to accommodate tall platters or pots in the bottom rack, as well as fold-down tines for custom configurations. For most daily uses, you won't notice a difference in loading capacity between them.
Price & Value
The KitchenAid 404 typically costs about $100-$200 more than the 304. Both are premium dishwashers that offer excellent performance and durability for their price. The value proposition comes down to your personal needs. For most users, the 304 delivers exceptional performance and a high-end experience that represents a great value. The extra cost for the 404 is justified if you will regularly use its specialized bottle wash feature or place a premium on having the absolute latest sensor technology.
Who Each One Works Best For
The KitchenAid Dishwasher 304 is the perfect workhorse for most modern households. It’s for the family or individual who wants a very quiet, efficient, and powerful dishwasher with lots of loading flexibility, without needing niche features. It offers 95% of the performance of the higher-end model for a lower price.
The KitchenAid Dishwasher 404 is geared toward families with young children, athletes with lots of water bottles, or anyone who frequently finds themselves hand-washing narrow-necked items. It’s also for the homeowner who appreciates subtle design upgrades and wants the smartest and most adaptable appliance technology KitchenAid offers in this line.

Frequently Asked Questions
What's the main difference between the KitchenAid 304 and 404?
The primary difference is that the 404 model includes more advanced ProWash sensors for smarter cleaning and adds a dedicated bottle wash cycle. The 404 also features a slightly more refined and intuitive control panel for an enhanced user experience.
Are both dishwashers quiet?
Yes, both the 304 and 404 operate at an identical 44 dBA, which is considered very quiet. This ensures they won't disturb conversations or other activities in an open-concept living space.
Do both the 304 and 404 have a third rack?
Yes, both models are equipped with KitchenAid's third-level utensil rack. This feature adds significant loading flexibility by providing a dedicated space for spatulas, silverware, and small cups, which frees up room on the lower racks.
Which model is more energy efficient?
Both models are ENERGY STAR certified, meaning they meet or exceed federal guidelines for energy and water efficiency. Their consumption levels are very similar, so there is no significant difference in energy savings between them.
Does the stainless steel finish resist fingerprints?
Both models often feature KitchenAid’s PrintShield™ Finish, which is a specialized coating on the stainless steel that resists smudges and fingerprints. It makes cleaning the exterior much easier and keeps the appliance looking spotless.
How is the interior tub constructed?
Both the 304 and 404 have stainless steel interior tubs. Stainless tubs are more durable than plastic, resist stains and odors, and can help with drying by retaining heat at the end of a cycle and promoting condensation.

KitchenAid dishwashers typically come with a standard one-year limited manufacturer's warranty covering parts and labor. Extended warranties may be available for purchase through the retailer.
Which dishwasher offers better value?
The answer depends on your needs. The KitchenAid 304 arguably offers better overall value for the average user, providing nearly all of the premium experience for a lower price. However, if the 404's bottle wash feature is a must-have for you, then its added convenience provides excellent value for that specific requirement.
