Whirlpool WDT740SALZ Reviews & Ratings by Customers and Consumer Reports

Designed for households that want a dependable, full-size built-in dishwasher without unnecessary complexity, the Whirlpool WDT740SALZ 24-inch dishwasher is best suited to busy families, rental properties, and everyday cooks who prioritize consistent cleaning, straightforward controls, and a clean, modern look. As an appliance specialist, I view this model as a practical “workhorse” option in Whirlpool’s lineup—focused on real-world usability rather than niche features. In day-to-day performance, the Whirlpool WDT740SALZ is built around the fundamentals that matter most: effective soil removal, stable wash coverage, and predictable drying results when loaded correctly. A stainless-steel tub is a meaningful durability and hygiene advantage in this class, helping resist staining and odors over time while supporting better heat retention during the drying phase. For many kitchens—especially in colder climates, including parts of Canada—heat retention can translate to more consistent end-of-cycle dryness, particularly on normal and heavy cycles. Usability is a strong point. Rack layout and adjustability are geared toward typical North American dish loads, with enough flexibility for mixed items like cereal bowls, cookware, and taller glasses. Controls and cycle selections are generally intuitive, which reduces the learning curve for multi-user households. Noise levels are typically well-managed for a modern built-in dishwasher, making it a reasonable fit for open-concept spaces, though ultra-quiet performance seekers may still prefer to verify the listed decibel rating for their specific installation needs. Efficiency is also aligned with current expectations: normal cycles are designed to balance water and energy use with cleaning performance, and the machine rewards good loading habits and proper detergent dosing. Like most dishwashers in this category, it performs best when users scrape (not rinse) heavy food soils and avoid blocking spray paths. Limitations are mainly about expectations. This model may not suit buyers who want premium-level drying for all plastics without using rinse aid, or those who prefer advanced cycle customization and specialty wash zones. As with many mid-tier dishwashers, plastics and lightweight items can retain some moisture, and heavily baked-on cookware may require a heavier cycle or pre-soak. Verdict: the Whirlpool WDT740SALZ is a solid choice for shoppers who want a durable, stainless-tub dishwasher with dependable everyday cleaning and easy operation. Those seeking top-tier drying performance, maximum rack modularity, or the quietest possible operation may want to consider more feature-forward alternatives.
