Positioned as a mid-to-high-range model, this dishwasher aims to solve the biggest frustration in open-concept living: the loud, grinding hum of a cleaning cycle.
The primary draw of the KDFS324SPS is its impressive 41 dBA noise rating. When you are paying for a KitchenAid, you are paying for a machine that cleans as well as it looks, and this model promises both through its PrintShield finish and ProWash technology. In this review, we will dive into the technical specifications and real-world performance to see if it truly earns its spot in your kitchen.
Key Features and Specifications
The Whisper Quiet Performance
The headline feature of the KitchenAid KDFS324SPS is the 41 dBA noise level. To put this into perspective, a standard conversation typically registers at 60 dBA, while a quiet library is around 40 dBA. Most budget dishwashers sit between 50 and 55 dBA, which is loud enough to require turning up the volume on a nearby television. At 41 dBA, this unit is virtually silent; you might find yourself checking the indicator light just to confirm it is actually running.
PrintShield Finish
For families with children or pets, the PrintShield™ Finish is a significant quality-of-life upgrade. Standard stainless steel is notorious for showing Every fingerprint and smudge, requiring constant buffing. KitchenAid's specialized coating resists smudges and fingerprints, making the exterior remarkably easy to clean with just a soft cloth and water. It maintains the professional look of stainless steel without the high-maintenance upkeep.
Rack Layout and Flexibility
This model features a 3rd Level Utensil Rack, which is designed to hold silverware, spatulas, and measuring cups. This clears up valuable space in the lower racks for larger pots and pans. Additionally, the middle rack is adjustable, allowing you to lower it to fit tall wine glasses or raise it to accommodate oversized platters on the bottom level. The tines are robust and well-spaced, accommodating a full load of 14 to 15 place settings with ease.
Cleaning Performance Test
ProWash Cycle
The KDFS324SPS utilizes the ProWash™ Cycle, which is a sensor-based cleaning system. Instead of simply running a timed wash, the sensors monitor the soil levels in the water throughout the cycle. If you have a particularly heavy load of greasy pans, the system automatically adjusts the water temperature and cycle time to ensure everything comes out spotless. This takes the guesswork out of choosing a cycle and helps conserve water when the dishes are only lightly soiled.
Drying Performance
Drying performance is often where mid-range dishwashers struggle, particularly with plastic containers. This KitchenAid model uses the Fan-Enabled ProDry™ system. It combines a heating element with a dedicated fan that circulates hot air around the tub. While no dishwasher is 100% perfect at drying the recessed bottoms of plastic Tupperware, the ProDry system is significantly more effective than the condensation drying found in many European-style models. Your glassware will typically come out streak-free and bone-dry.
KitchenAid KDFS324SPS vs. The Competition
Vs. Bosch 800 Series
The most common comparison for this KitchenAid is the Bosch 800 Series. While Bosch is famous for its CrystalDry technology (which uses minerals to generate heat), KitchenAid relies on the fan-assisted ProDry system. Bosch 800 models are also exceptionally quiet (usually 42 dBA), but many users prefer the KitchenAid's more traditional American-style rack layout and the specific look of the KitchenAid knurled handle. KitchenAid tends to have more robust tines, while Bosch focuses on maximum density.
Vs. Whirlpool Lower Tier
Whirlpool (which owns KitchenAid) offers several models that look similar for $200 to $300 less. However, the upgrade to the KDFS324SPS is usually worth it for two reasons: noise and build quality. The Whirlpool models generally run at 47 to 50 dBA and lack the 3rd level rack and the fan-assisted drying system. If you spend any time in your kitchen while the dishwasher is running, the silence of the KitchenAid provides a tangible upgrade in home comfort.
Pros and Cons
Pros
- Extremely Quiet: At 41 dBA, it is one of the quietest models in its price bracket.
- Professional Aesthetics: The knurled handle and PrintShield finish provide a high-end look.
- Effective Drying: The fan-enabled system handles plastics better than many competitors.
- 3rd Rack Utility: Greatly increases the capacity for small items and silverware.
Cons
- Cycle Times: Like most high-efficiency dishwashers, a full heavy-duty cycle can take over 2 hours.
- Price Point: It is a significant investment compared to entry-level stainless steel models.
- Depth: The professional handle sticks out further than pocket-handle models, which may be a concern in very narrow galleys.
Final Verdict
The KitchenAid KDFS324SPS is an excellent choice for homeowners with open-concept floor plans where kitchen noise carries into the living area. It strikes a nearly perfect balance between high-end cleaning technology and user-friendly features like the PrintShield finish. If you have a large family or frequently host dinner parties, the rack flexibility and 3rd level utensil tray will be highly utilized.
While the cycle times are long, the results are consistent. If you want a dishwasher that you can start after dinner and completely forget about while you watch a movie ten feet away, this is the machine for you.
