Detailed Product Reviews

1. Kenmore 24" Built-In Dishwasher - UltraWash Plus, EasyFlex Third Rack, TurboDry, SmartWash & Reach-Thru Handle - 15 Place Settings - 45 DBA - ENERGY STAR Certified - Stainless Steel

Kenmore 24" Built-In Dishwasher - UltraWash Plus, EasyFlex Third Rack, TurboDry, SmartWash & Reach-Thru Handle - 15 Place Settings - 45 DBA - ENERGY STAR Certified - Stainless Steel

Overview: This Kenmore dishwasher positions itself as a feature-packed mid-range option for busy households. With a 45 dBA noise level, 15-place-setting capacity, and ENERGY STAR certification, it balances performance with efficiency. The stainless steel finish and hidden touch controls give it a modern aesthetic that fits most kitchens.

What Makes It Stand Out: The EasyFlex Third Rack is a game-changer, adding 35% more loading space for utensils and tools while remaining removable when you need height below. The TurboDry system combines a built-in fan with a heating element, delivering remarkably dry dishes—even plastics. SmartWash technology automatically adjusts water temperature and pressure based on soil levels, while built-in leak detection provides peace of mind. The Accela Wash and Sani Rinse options add versatility for time-pressed or hygiene-conscious users.

Value for Money: At $593, this model sits in the sweet spot between budget and premium. You’re getting high-end features like sensor washing, third-rack flexibility, and superior drying typically found in $700+ units. The ENERGY STAR rating ensures long-term utility savings, making it a smart investment for families who run daily cycles.

Strengths and Weaknesses: Strengths include exceptional drying performance, flexible loading options, quiet operation, smart sensors, and proactive leak protection. The 45 dBA rating is impressively quiet, though not library-silent. Weaknesses are minor: the third rack adjusts by removal rather than sliding, and hidden controls may require a learning curve.

Bottom Line: This Kenmore delivers premium features at a mid-tier price. It’s ideal for families seeking flexibility, quiet operation, and superior drying without breaking the bank. Highly recommended.


2. Sharp SDW6726MS 24-inch Stainless Steel Dishwasher, 47 dB Library Quiet, Third Rack, Power Wash Sprayer, 12 Place Settings,

Sharp SDW6726MS 24-inch Stainless Steel Dishwasher, 47 dB Library Quiet, Third Rack, Power Wash Sprayer, 12 Place Settings,

Overview: Sharp’s entry-level SDW6726MS targets compact households seeking quiet operation without premium pricing. At 47 dB with Library Quiet technology, it’s suitable for open-concept living and nighttime cycles. The 12-place-setting capacity and stainless steel construction make it a solid, if basic, performer for smaller families who prioritize peace over maximum loading space.

What Makes It Stand Out: The Power Wash sprayer is the headline feature—a specialized third sprayer that tackles heavily soiled dishes with enhanced scrubbing power. Built-in soil sensors automatically adjust cycles for optimal cleaning efficiency, while the adjustable third rack provides dedicated space for flatware. The front touch controls offer straightforward operation without complexity, keeping the interface clean and user-friendly for all household members.

Value for Money: Priced at $579, it competes directly with mid-range offerings but delivers fewer premium features. The 12-place-setting capacity limits its appeal for larger families compared to 15-setting competitors at similar prices. However, the Power Wash system and quiet operation justify the cost for those prioritizing targeted cleaning power over capacity and advanced drying technology.

Strengths and Weaknesses: Strengths include genuinely quiet performance, effective soil sensors, and the targeted Power Wash sprayer that handles tough messes. The stainless steel finish is durable and attractive. Weaknesses are notable: limited 12-place-setting capacity, a basic third rack without slide adjustments, and the absence of a dedicated drying system like TurboDry. Cycle options are fewer than competitors, and there’s no leak detection mentioned.

Bottom Line: Best suited for couples or small families in apartments or open-concept homes where quiet operation is paramount and loads are consistently small. For larger households, consider capacity-first alternatives that offer more flexibility.


3. Sharp SDW6736MS 24-inch Stainless Steel Dishwasher, Third Rack, Library Quiet 47 dB, Power Wash Sprayer

Sharp SDW6736MS 24-inch Stainless Steel Dishwasher, Third Rack, Library Quiet 47 dB, Power Wash Sprayer

Overview: The SDW6736MS is Sharp’s enhanced version of their quiet dishwasher line, maintaining the 47 dBA rating and 12-place-setting capacity while adding meaningful upgrades that improve flexibility. It targets eco-conscious smaller households wanting more customization without increasing budget or noise levels.

What Makes It Stand Out: The third rack slides right-to-left, creating on-demand space—a notable improvement over the fixed rack in its sibling model. Wash Zones allow efficient half-load cleaning, reducing water and energy waste for more sustainable operation. The Power Wash sprayer remains, now complemented by heated dry capability and expanded cycles (6) and options (7), offering superior customization compared to most competitors in this price range.

Value for Money: At $579, identical in price to the SDW6726MS, this model is clearly the better Sharp value. You’re getting premium features like Wash Zones and enhanced drying at no extra cost. However, the 12-place-setting capacity still lags behind similarly priced competitors offering 15 settings, making it less ideal for growing families who need maximum loading flexibility.

Strengths and Weaknesses: Strengths include the flexible sliding third rack, efficient Wash Zones for small loads, comprehensive cycle selection, and genuine quiet operation. The stainless steel tub adds durability and improves drying performance. Weaknesses center on limited capacity, absence of leak detection, and a drying system less robust than fan-assisted alternatives. The 47 dBA rating, while quiet, isn’t class-leading.

Bottom Line: Choose this over the SDW6726MS for its superior flexibility and efficiency. Perfect for small households or eco-minded users who prioritize customization and quiet operation over raw capacity.


4. Kenmore Elite 24" Built-In Dishwasher - UltraWash Plus, TurboDry, QuietWash, SmartWash & TurboFlex Third Rack - 15 Place Settings - 42 DBA - ENERGY STAR Certified - Stainless Steel

Kenmore Elite 24" Built-In Dishwasher - UltraWash Plus, TurboDry, QuietWash, SmartWash & TurboFlex Third Rack - 15 Place Settings - 42 DBA - ENERGY STAR Certified - Stainless Steel

Overview: The Kenmore Elite represents the brand’s flagship offering, engineered for discerning homeowners who demand near-silent operation. At just 42 dBA, it’s one of the quietest dishwashers in its class, while maintaining 15-place-setting capacity and ENERGY STAR efficiency. The premium stainless steel design includes hidden controls and an LED status light.

What Makes It Stand Out: The TurboFlex Third Rack delivers 35% more loading space with enhanced adjustability. The MoreSpace Plus Upper Rack offers three height levels—unmatched flexibility for accommodating tall items. The combination of TurboDry’s fan-plus-heating-element system and SmartWash sensors ensures pristine results. QuietWash mode and the LED floor light exemplify thoughtful design for noise-sensitive environments.

Value for Money: At $830, this is a significant investment, positioning it against Bosch 800 series and entry-level Miele models. The value proposition hinges on whether you need 42 dBA silence and three-position rack adjustment. For large families in open-concept homes, the premium is justified. For others, the standard Kenmore at $593 offers better ROI.

Strengths and Weaknesses: Strengths include class-leading quietness, exceptional rack flexibility, superior drying performance, and comprehensive smart features. The build quality feels premium. Weaknesses are primarily cost-related—many features overlap with the cheaper Kenmore model. The Elite premium may be unnecessary for smaller households or those less sensitive to noise.

Bottom Line: If your budget allows and silence is paramount, this Elite model is outstanding. For most buyers, however, the standard Kenmore offers nearly identical performance at a 30% discount.


5. Kenmore 22-14632 24" Built-In Dishwasher - UltraWash Plus, SmartWash, Accela Wash, Sanitize Rinse, TurboDry, and Removable Third Rack - 15 Place Settings - 49 DBA - ENERGY STAR Certified - 24" - White

Kenmore 22-14632 24" Built-In Dishwasher - UltraWash Plus, SmartWash, Accela Wash, Sanitize Rinse, TurboDry, and Removable Third Rack - 15 Place Settings - 49 DBA - ENERGY STAR Certified - 24" - White

Overview: This budget-friendly Kenmore sacrifices some refinement to deliver core performance at an accessible price point. At 49 dBA, it’s the loudest in our comparison but still conversation-friendly and suitable for most homes. The white finish and 15-place-setting capacity make it practical for cost-conscious families prioritizing function over modern aesthetics.

What Makes It Stand Out: The Express Cycle cleans a full load in just 50 minutes—perfect for entertaining or busy weeknights. The Half Load option optimizes water and energy for smaller batches, a rare feature at this price. It retains TurboDry technology and SmartWash sensors, ensuring you don’t compromise on drying or intelligent cleaning despite the lower cost. Leak detection adds unexpected security and peace of mind.

Value for Money: At $445, this is exceptional value. You’re getting 15-place capacity, TurboDry, sensor washing, and a third rack—features typically reserved for $600+ models. The white finish limits aesthetic appeal, but functionally, it outperforms most competitors under $500. For rental properties or budget renovations, it’s nearly unbeatable and offers tremendous bang for your buck.

Strengths and Weaknesses: Strengths include outstanding affordability, full capacity, rapid Express Cycle, efficient Half Load option, and retained premium drying technology. Leak detection is a welcome safety net. Weaknesses are the 49 dBA noise level—noticeable in quiet homes—and the lack of rack adjustability or sliding third rack. The white finish may clash with modern stainless kitchens.

Bottom Line: For budget-focused buyers needing capacity and reliable performance, this is a standout choice. Accept the modest noise level and white finish, and you’ll save nearly $150 without sacrificing cleaning quality or essential features.

At just 42dBA, this fully integrated model delivers library-quiet performance while offering advanced features like Alexa voice control and a deep third rack for enhanced capacity.

What Makes It Stand Out: Library Quiet technology ensures peaceful operation at 42dBA, while the Power Wash sprayer tackles heavily soiled items with precision.

With six wash cycles and seven options, it adapts to any load.

Value for Money: Priced at $799.10, this dishwasher sits in the premium tier but justifies its cost through smart capabilities and exceptional quietness. Comparable smart models from other brands often exceed $900, making this a competitive choice for tech-savvy homeowners seeking luxury features without the highest price tag.

Strengths and Weaknesses: Pros: Exceptionally quiet 42dBA operation, Alexa voice control integration, effective Power Wash sprayer, flexible third rack, LED interior lighting, heated dry option.

Bottom Line: Ideal for modern kitchens where silence and convenience are paramount, the Sharp SDW6888JS delivers premium performance that tech enthusiasts will appreciate. The smart features and ultra-quiet operation make it worth the investment for those who value peace and connectivity.

Despite its reduced footprint, it maintains impressive functionality with eight place settings and a convenient third rack for utensils.

What Makes It Stand Out: This model’s wash zones allow independent upper or lower rack operation for smaller loads, conserving water and energy. The ultra-quiet 47dB performance ensures minimal disruption, while smart sensors automatically optimize cleaning. The fingerprint-resistant exterior and backlit touch controls add premium touches to its space-saving design.

Value for Money: At $799, this compact model commands a premium price, but it delivers features often missing in smaller dishwashers. The third rack and smart sensors are rare in 18-inch units, justifying the cost for urban dwellers or those with limited kitchen space who refuse to compromise on performance.

Strengths and Weaknesses: Pros: Space-efficient 18-inch width, independent wash zones, fingerprint-resistant finish, quiet operation, third rack inclusion, smart sensor technology. Cons: Limited eight place setting capacity, premium pricing approaches full-size models, may not suit larger households.

Bottom Line: Perfect for apartments, condos, or small kitchens, the Sharp SDW4523MS proves that compact doesn’t mean basic. Its intelligent features and flexible washing options make it the best choice for space-conscious buyers seeking premium performance.

The Smart Dishwasher Revolution Meets Third-Rack Innovation

The marriage of intelligent connectivity and adaptable interior design represents the most significant leap in dishwasher engineering in decades. Smart dishwashers bring a level of convenience and efficiency that goes far beyond basic automation, while third-rack flexibility addresses the real-world loading challenges that have plagued users since the first home dishwasher rolled off assembly lines.

What “Smart” Really Means in Dishwashing

A truly smart dishwasher does more than connect to your Wi-Fi network. It leverages sensors, artificial intelligence, and cloud connectivity to optimize performance, predict maintenance needs, and integrate seamlessly with your daily routines. These appliances can detect soil levels on dishes, adjust water pressure and temperature in real-time, and even order detergent automatically when supplies run low. The intelligence extends beyond the machine itself, creating a symbiotic relationship between the appliance, your smartphone, and your broader smart home ecosystem.

The Evolution of the Third Rack

The third rack began as a simple sliding tray for cutlery, but it has evolved into a sophisticated, flexible system that can accommodate everything from mason jar lids to culinary whisks. Early iterations were often fixed and shallow, limiting their utility. Modern flexible third racks feature adjustable tines, removable sections, and deeper wells that transform how you load unconventional items. This evolution reflects a fundamental shift from standardized design to user-centric adaptability.

Why Third-Rack Flexibility Changes Everything

The addition of a flexible third rack fundamentally alters your dishwasher’s capacity and versatility. It’s not merely about adding space—it’s about reimagining how that space can be used based on your specific needs on any given day.

Maximized Loading Capacity

A flexible third rack can increase your dishwasher’s capacity by up to 30%, allowing you to fit more items per load and run fewer cycles over time. By moving utensils and smaller items to the top, you free up valuable real estate in the lower racks for larger plates, pots, and pans. This efficiency translates directly into water and energy savings, as well as reduced wear on your dishes from fewer wash cycles.

Specialized Utensil and Tool Cleaning

Traditional cutlery baskets cram utensils together, often resulting in nesting that prevents proper cleaning and water drainage. A well-designed third rack spreads items out individually, ensuring complete water coverage and eliminating the dreaded “spoon nest” phenomenon. This is particularly crucial for bulky kitchen tools like tongs, spatulas, and measuring spoons that never quite fit properly in standard baskets.

Adaptability for Different Load Types

The real magic happens when you can reconfigure the third rack based on your load. Hosting a cocktail party? Remove sections to make room for dozens of stemless wine glasses. Meal prepping for the week? Adjust tines to secure multiple food processor blades and container lids. This adaptability means your dishwasher works for your lifestyle, not the other way around.

Essential Smart Features to Prioritize

Not all smart features deliver equal value. Some genuinely transform your experience, while others amount to little more than app-based gimmicks. Knowing the difference helps you invest wisely.

Remote Monitoring and Control

The ability to start, stop, or monitor your dishwasher from anywhere provides genuine convenience. Check cycle status while running errands, receive alerts when detergent is low, or schedule cycles during off-peak energy hours—all from your smartphone. Look for apps that offer detailed diagnostics and maintenance reminders, not just basic start/stop functionality.

Automatic Detergent Ordering

Integration with e-commerce platforms represents one of the most practical smart features available. Sensors track your usage patterns and automatically reorder detergent pods or rinse aid before you run out. This eliminates the frustration of discovering an empty box on a Sunday evening when stores are closed. The best systems allow you to customize reorder thresholds and choose your preferred brands.

Smart Cycle Selection and Optimization

Advanced soil sensors can detect how dirty your dishes are and automatically select the appropriate cycle, water temperature, and duration. Some models even use machine learning to recognize your household’s patterns, suggesting optimal run times and predicting when you’ll need to run your next load. This feature removes guesswork and ensures you’re never wasting resources on an unnecessarily intense cycle.

Integration with Smart Home Ecosystems

True smart appliances play nicely with others. Look for compatibility with major platforms like Amazon Alexa, Google Home, or Apple HomeKit. The best integrations allow you to create routines—like starting the dishwasher automatically when you leave the house or running a cycle when your solar panels are producing peak energy.

Decoding Third-Rack Designs

Third racks come in various configurations, each with distinct advantages. Understanding these differences helps you match the design to your specific kitchenware collection.

Fixed vs. Adjustable Third Racks

Fixed racks offer simplicity but limited versatility. Adjustable racks, featuring movable or removable sections, provide the flexibility to accommodate taller items in the middle rack when needed. Some premium models offer split-rack designs where you can raise or lower one side independently, creating a truly customizable loading environment.

Deep Third Racks for Oversized Items

Standard third racks struggle with larger utensils and cooking tools. Deep-rack designs feature increased vertical clearance, allowing you to lay down bulky items like ladles, whisks, and even small saucepan lids. This design is particularly valuable for serious home cooks who regularly use professional-grade tools.

Convertible Racks for Custom Loads

The most advanced third racks can transform entirely—converting from a utensil tray to a glassware rack or even a shallow pan holder. These convertible systems often feature collapsible tines and removable dividers, giving you the freedom to create custom configurations for unique loads.

Sizing and Space Considerations

Even the most feature-rich dishwasher fails if it doesn’t fit your kitchen layout or accommodate your household’s volume of dishes.

Standard Dimensions and Built-in Models

Most full-size dishwashers measure 24 inches wide, 24 inches deep, and 34 inches tall, designed to fit under standard countertops. However, third-rack models sometimes require slightly more interior height. Always measure your existing space carefully, accounting for any irregularities in flooring or cabinetry that might affect installation.

Compact and Drawer-Style Options

For smaller kitchens or households, compact 18-inch models and drawer-style dishwashers now offer third-rack flexibility. These space-saving designs often feature split drawers that can run independently, providing third-rack functionality in a more versatile package. They’re ideal for apartments, condos, or secondary kitchen spaces.

Performance Metrics That Matter

Technical specifications tell the real story behind marketing claims. Understanding these metrics ensures you choose a dishwasher that delivers on its promises.

Cleaning Power and Spray Patterns

Look beyond the number of spray arms and examine the coverage patterns. Smart dishwashers often feature targeted spray zones that activate based on load sensors. The best models use alternating spray patterns and variable pressure to ensure every item receives adequate water coverage, regardless of its position in the flexible third rack.

Drying Effectiveness and Technologies

Third racks can sometimes impede drying if not properly engineered. Advanced drying technologies like zeolite crystals, auto-opening doors, and fan-assisted drying ensure even plastic items on the top rack emerge completely dry. Some smart models adjust drying time and temperature based on humidity sensors and the specific materials detected in the load.

Energy and Water Consumption

Smart dishwashers with third racks should be more efficient, not less. Check for ENERGY STAR certification and compare annual operating costs. The most efficient models use as little as 2.5 gallons per load while still delivering superior cleaning. Smart features like leak detection and water usage monitoring provide additional conservation benefits.

Noise Levels and Quiet Operation

A flexible third rack can sometimes create more noise if items aren’t secured properly. Premium models feature sound insulation and brushless motors that operate below 40 decibels—quieter than a library. Smart apps can even alert you if rattling is detected during a cycle, allowing you to pause and rearrange items remotely.

Installation and Compatibility

The smartest dishwasher in the world becomes a paperweight if it doesn’t integrate properly with your home’s infrastructure.

Electrical and Plumbing Requirements

Most smart dishwashers require a dedicated 120-volt, 15-amp circuit and a standard hot water supply line. However, smart models may need a stronger Wi-Fi signal near the appliance. Consider installing a Wi-Fi extender if your router is far from the kitchen. Some models also require a specific water pressure range to operate sensors correctly.

Smart Home Network Prerequisites

Before purchasing, audit your home network. Smart dishwashers need stable 2.4GHz Wi-Fi (some support 5GHz) and may struggle on congested networks. Ensure your router can handle additional devices and consider creating a separate IoT network for security. Check compatibility with your existing smart home hub to avoid fragmentation.

Professional vs. DIY Installation

While many dishwashers can be self-installed, smart models often benefit from professional setup to ensure proper connectivity calibration and sensor testing. Professionals can also verify that your cabinetry and countertops can support the specific model, especially if you’re upgrading from a standard two-rack unit to a third-rack design.

Budgeting and Value Assessment

Smart dishwashers with third-rack flexibility span a wide price range. Understanding what you’re paying for helps maximize your investment.

Price Tiers and What to Expect

Entry-level smart third-rack models start around $800, offering basic connectivity and a simple adjustable rack. Mid-range options ($1,200-$1,500) add advanced sensors, better materials, and more sophisticated third-rack designs. Premium models ($1,800+) feature cutting-edge drying technology, superior build quality, and the most flexible rack systems.

Total Cost of Ownership

Factor in operating costs over the appliance’s 10-12 year lifespan. Energy-efficient models may cost more upfront but save hundreds in utility bills. Consider detergent costs—smart ordering features might lock you into specific brands at premium prices. Warranty length and service availability also impact long-term value.

When to Invest in Premium Features

Serious home cooks, large families, and tech enthusiasts benefit most from premium models. If you run your dishwasher daily, use specialized cookware, or have already invested in a smart home ecosystem, the additional cost pays dividends in convenience and performance. For occasional users, a mid-range model often provides the best balance.

Maintenance and Longevity

Smart features and flexible racks introduce new maintenance considerations that differ from traditional dishwashers.

Self-Cleaning Functions and Filters

Look for models with automatic filter cleaning and cycle reminders. Smart dishwashers can notify you when it’s time to clean the spray arms or run a maintenance cycle. Some even track water hardness and adjust settings to prevent mineral buildup, extending the life of internal components.

Software Updates and Security

Your dishwasher’s software needs regular updates to maintain security and functionality. Choose brands with a proven track record of long-term support. Check whether updates are automatic or require manual initiation, and understand the manufacturer’s policy on supporting older models. Security features like encrypted connections protect your home network.

Warranty Coverage Essentials

Standard warranties cover 1-2 years, but premium models often offer 5-10 year coverage on major components. Pay special attention to rack and rail warranties—these moving parts experience the most wear. Some manufacturers offer extended warranties that specifically cover smart components and sensors, which can be expensive to replace out-of-pocket.

Frequently Asked Questions

What exactly is a “third rack” in a dishwasher?

A third rack is a sliding tray located at the very top of the dishwasher tub, above the traditional upper rack. It’s designed to hold utensils, small bowls, lids, and other items that don’t fit well in standard baskets. Flexible third racks feature adjustable or removable sections to accommodate larger items and customize the loading space based on your needs.

Are smart dishwashers worth the extra cost?

Smart dishwashers justify their premium price if you value convenience, efficiency, and integration. Features like remote monitoring, automatic detergent ordering, and cycle optimization save time and prevent waste. For busy households or smart home enthusiasts, the benefits often outweigh the additional upfront cost. However, if you rarely use your dishwasher or don’t need remote access, a standard model may suffice.

Can I add a third rack to my existing dishwasher?

Unfortunately, third racks cannot be retrofitted to standard two-rack dishwashers. The entire tub design, spray arm configuration, and water distribution system are engineered specifically to accommodate a third rack. Upgrading requires purchasing a new dishwasher designed with this feature from the ground up.

What happens if the Wi-Fi goes out? Can I still run my smart dishwasher?

Yes, smart dishwashers function perfectly as traditional appliances without Wi-Fi. You can operate all basic cycles using the control panel. However, you’ll lose remote access, notifications, and smart features until connectivity is restored. Most models store usage data locally and sync it once the connection is reestablished.

How do I know if a third rack will fit my larger utensils?

Check the rack’s vertical clearance specifications in the product manual. Look for “deep rack” or “adjustable height” features if you regularly wash bulky items. Many manufacturers provide dimensional diagrams showing maximum item heights. Visiting a showroom with your actual utensils for a test fit is the most reliable way to verify compatibility.

Are smart dishwashers difficult to set up and connect?

Most modern smart dishwashers feature streamlined setup processes through companion apps. You’ll typically scan a QR code, connect to your 2.4GHz Wi-Fi network, and follow in-app prompts. The entire process usually takes 10-15 minutes. However, homes with complex network setups or mesh systems may require additional troubleshooting.

Do third racks really clean as well as traditional baskets?

When properly designed, third racks clean better than baskets because items are separated and receive direct water spray from dedicated jets. The key is water pressure and coverage. Premium models include targeted spray zones specifically for the third rack. Avoid overloading and ensure items are properly spaced for optimal results.

What smart features are actually useful versus gimmicky?

Truly useful features include remote monitoring, leak detection, automatic reordering, and cycle optimization based on soil levels. Gimmicky features might include playing music through the appliance speaker or overly complex app interfaces. Focus on features that solve real problems or save tangible time and money.

How much more do third-rack smart dishwashers cost?

Expect to pay $200-$400 more than comparable two-rack smart models, and $400-$600 more than non-smart two-rack units. The premium covers additional materials, engineering complexity, and sensor technology. Mid-range options around $1,200-$1,400 typically offer the best balance of features and value for most households.

What maintenance do smart dishwashers require compared to standard models?

Smart dishwashers require the same basic maintenance as standard models—cleaning filters, inspecting spray arms, and running occasional cleaning cycles. Additionally, you should keep the companion app updated, ensure firmware is current, and periodically check Wi-Fi connectivity. The smart components themselves are typically sealed and maintenance-free, but software updates are crucial for security and performance.
