Both dishwashers cater to households needing efficient cleaning solutions, but they offer distinct features that appeal to different preferences and needs. The Sharp model emphasizes quiet operation and a sophisticated design, while the Whirlpool focuses on robust cleaning capabilities and practicality.
Noise Level and Operation
The Sharp SDW6726MS operates at a remarkably quiet 47 dBA, making it ideal for open-concept homes where noise can be disruptive. In contrast, the Whirlpool WDP540HAMZ has a slightly louder operation at 55 dBA. While still relatively quiet, the difference in noise levels could affect your choice, especially if you often run your dishwasher during meals or late at night. The Sharp's Library Quiet technology ensures a peaceful kitchen environment, which might be a deciding factor for noise-sensitive households.
Cleaning Performance
The Sharp SDW6726MS features a powerful three-sprayer system with a specialized Power Wash sprayer that targets stubborn, heavily soiled dishes effectively. It also incorporates built-in soil sensors that automatically adjust wash cycles for optimal cleaning performance. Conversely, the Whirlpool WDP540HAMZ includes a Boost Cycle designed to tackle tough messes without the need for pre-rinsing. Its triple filtration wash system helps keep wash water cleaner, preventing food from redepositing on dishes. Both dishwashers provide excellent cleaning, but the Sharp offers advanced technology for delicate and stubborn cleaning needs.
Capacity and Flexibility
Both dishwashers can accommodate up to 12 place settings, making them suitable for medium-sized families. However, the Sharp SDW6726MS stands out with its adjustable third rack, allowing for enhanced storage flexibility, especially for flatware and serving utensils. This feature maximizes loading capacity and optimizes space usage. The Whirlpool WDP540HAMZ, while efficient, does not mention a third rack but still provides practical interior design features to facilitate easy loading and unloading. For households that frequently entertain or have larger dishwashing needs, the Sharp's design may offer a significant advantage.
Wash Cycles and Options
The Sharp SDW6726MS comes with five wash cycles and four additional options, including a heated dry feature that enhances drying performance. The Whirlpool WDP540HAMZ also offers five wash cycles, including a Quick Wash and Extended Soak, but adds options like High Temperature Wash and Sani Rinse for sanitizing dishes. While both models provide versatile washing capabilities, the addition of specialized options in the Whirlpool may appeal to users looking for more control over their washing preferences.
Design and Aesthetics

The Whirlpool WDP540HAMZ features a hybrid tub with a dark gray interior, designed to conceal stains while providing a durable washing environment. The visual appeal of both dishwashers aligns with modern kitchen designs, but the Sharp's fingerprint-resistant feature may be more attractive for those concerned about maintenance and cleanliness.
Reliability and Sales Performance
The Sharp SDW6726MS holds a sales rank of 979, while the Whirlpool WDP540HAMZ is slightly higher at 874. This indicates that the Whirlpool may have a slight edge in terms of popularity in the market.

The sales rank may influence your decision if you believe that higher popularity reflects better performance or customer preference.
Which should you buy?
When choosing between the Sharp SDW6726MS and the Whirlpool WDP540HAMZ, consider your specific needs. If quiet operation and advanced cleaning technology are your priorities, the Sharp SDW6726MS is a compelling option despite its higher price. However, if you seek a more budget-friendly choice with practical cleaning features and good performance, the Whirlpool WDP540HAMZ is an excellent alternative. Ultimately, both models deliver solid performance, but your decision may hinge on features that align best with your lifestyle and kitchen habits.
