Kenmore 22-14589 24" Built-In Dishwasher - UltraWash, SmartWash, Sanitize Rinse, SmartDry, and Leak Detection - 14 Place Settings - 57 DBA - ENERGY STAR Certified - 24" - Black vs Sharp SDW6504MS Stainless Steel Dishwasher, 24-inch Pocket Handle, 52 dB, Hybrid Tub, 12 Place Settings, 5 Cycles, Heated Dry

Price and Value Comparison

The Kenmore 22-14589 is about 50% more expensive than the Sharp SDW6504MS, priced at $599.99 compared to $399.00. This $200.99 difference represents a significant upfront cost gap. However, the Kenmore’s higher price is justified by its ENERGY STAR certification and advanced features like SmartWash, Sani Rinse, and leak detection, which are absent in the Sharp model. The Sharp dishwasher offers better value for budget-conscious buyers seeking reliable performance without premium extras. Despite being less expensive, the Sharp ranks higher in bestseller rank (132 vs. 1496), suggesting stronger consumer demand at a lower price point.

Capacity and Interior Design

The Kenmore 22-14589 accommodates up to 14 place settings, offering two more than the Sharp SDW6504MS’s 12-place setting capacity. This extra space is enabled by a MoreSpace Adjustable Upper Rack that can be raised, lowered, or removed entirely, providing flexibility for tall items and delicate stemware. The Sharp model includes an adjustable upper rack with a 2-inch height adjustment, allowing room for taller dishes but lacking the full removal option. Both dishwashers feature fold-down tines for flexible loading, though only the Kenmore explicitly mentions a half-load option. The Kenmore’s larger interior makes it better suited for larger households or frequent entertaining.

Cleaning Performance and Technology

The Kenmore 22-14589 uses SmartWash technology to detect soil levels and automatically adjust water temperature, pressure, and cycle time, ensuring optimal cleaning without user input. It also features a 3-stage UltraWash Filter that captures particles as small as a grain of fine sand. The Sharp SDW6504MS relies on standard cycles without sensor-based adjustments, though it does include a sanitization cycle to reduce bacteria. While both offer five wash cycles, the Kenmore’s combination of sensor-driven optimization and multi-stage filtration provides a more intelligent and thorough clean. The absence of such automation in the Sharp means users must manually select the appropriate cycle based on load type.

Drying Efficiency and Features

Both dishwashers include a heated dry option, but the Kenmore’s SmartDry technology goes further by selecting the best drying cycle and adjusting for optimized performance. It uses hot water to promote condensation on the stainless tub, directing moisture down the drain—ensuring dishes come out cabinet-ready. The Sharp SDW6504MS offers heated dry as well, but no mention is made of adaptive drying logic or condensation management. The Kenmore also includes an Extra Dry option for hard-to-dry items, a feature not present in the Sharp model. These differences suggest the Kenmore delivers superior drying results, especially for plastic or non-porous materials.

Noise Level and Quiet Operation

The Sharp SDW6504MS operates at just 52 dBA, described as library quiet, making it ideal for open-concept kitchens or homes where noise is a concern. The Kenmore 22-14589 is rated at 57 dBA, slightly louder but still within typical residential ranges. While both models are designed for quiet operation, the Sharp’s lower decibel rating gives it a clear advantage in noise-sensitive environments. The Kenmore’s higher noise level may be noticeable during evening use, particularly if the kitchen is adjacent to living areas. For those prioritizing silence, the Sharp is the better choice.

Build Quality and Durability

The Kenmore 22-14589 features a stainless steel tub that retains heat and resists stains, contributing to long-term durability and efficient drying. Its 3-stage filter system is designed for easy removal and monthly cleaning, enhancing maintenance convenience. The Sharp SDW6504MS uses a hybrid construction combining a stainless steel interior with a heavy-duty plastic floor, aiming for durability while reducing cost. While this design may compromise some heat retention, it maintains structural integrity. The Kenmore’s all-stainless interior suggests greater resistance to corrosion and longer lifespan, though neither model specifies material longevity beyond these details.

Safety and Smart Features

The Kenmore 22-14589 includes built-in leak detection that monitors water flow and automatically drains the tub if a problem is detected, helping prevent water damage before it starts. This feature is not mentioned in the Sharp SDW6504MS specifications. Additionally, the Kenmore offers Delay Start for scheduling cycles up to 24 hours in advance, useful for off-peak energy usage. The Sharp includes a child lock feature to prevent accidental starts, a safety benefit absent in the Kenmore’s description. Both models have back-lit control panels, but only the Sharp explicitly highlights this for ease of use. The Kenmore’s suite of smart features—including automatic cycle adjustment and leak protection—offers a more comprehensive safety and convenience profile.

Which should you buy?

Choose the Kenmore 22-14589 if you prioritize maximum capacity (14 place settings), advanced cleaning intelligence (SmartWash, 3-stage filter), superior drying (SmartDry, Extra Dry), and proactive leak detection—all backed by ENERGY STAR certification. Though priced $200.99 higher at $599.99, its robust feature set justifies the cost for families needing consistent, high-performance cleaning. Opt for the Sharp SDW6504MS if you want a quieter, more affordable option at $399.00 with a sleek pocket handle, 52 dBA operation, and sufficient capacity for smaller households. Its hybrid tub and child lock add practical value, but it lacks the Kenmore’s automated sensors, enhanced filtration, and leak protection. For most buyers seeking balance between price and performance, the Sharp offers better value—but for those willing to invest in smarter, safer cleaning, the Kenmore is the superior choice.
