Price Comparison
The EdgeStar BIDW1802SS is priced at $539.00, while the Whirlpool WDP540HAMZ is about 17% cheaper at $459.00. This significant price difference may influence your decision, especially if you are budget-conscious. The EdgeStar, with a higher price point, offers a capacity for eight place settings, which is less than the Whirlpool's twelve. If you need a larger capacity without the higher price tag, the Whirlpool may be the better option for you.
Size and Design
The EdgeStar BIDW1802SS is designed to fit into tighter spaces, measuring only 18 inches wide, making it a great choice for smaller kitchens or for replacing older appliances like trash compactors. In contrast, the Whirlpool WDP540HAMZ measures 24 inches wide, providing a more spacious interior that accommodates up to 12 place settings. If kitchen space is a constraint, the EdgeStar's compact design could be advantageous; however, for larger households, the Whirlpool's capacity may prove to be more beneficial.
Wash Cycles and Options
The EdgeStar offers six wash cycles, including Heavy, Normal, ECO, Glass, Rapid, and Rinse, along with three additional options such as Sanitize and Hi Temp. On the other hand, the Whirlpool boasts five wash cycles—Boost, Extended Soak, Heavy, Normal, and Quick Wash—and several options, including High Temperature Wash and Sani Rinse. While both models have versatile wash cycles, the EdgeStar's additional cycles provide more flexibility for various washing needs. However, the Whirlpool's Boost Cycle is designed specifically for tough messes, offering a quicker solution for stubborn food residue.
Noise Level
When it comes to noise, the EdgeStar operates quietly at 52 decibels, while the Whirlpool is slightly louder at 55 decibels. This difference may not be significant, but if a peaceful kitchen environment is a priority for you, the EdgeStar could be the more appealing option. Both dishwashers are designed to minimize disturbance, making them suitable for use during meals or overnight.
Interior Features
The EdgeStar features a silverware basket and cup tray, which helps in organizing utensils effectively. The Whirlpool, however, employs a triple filtration wash system that enhances cleaning performance by preventing food particles from re-depositing on dishes. Additionally, the Whirlpool has nylon-coated racks for durability and ease of use. If interior design and organization are important, the Whirlpool may offer more practical features for everyday use, while the EdgeStar focuses on compact functionality.
Safety Features
Safety is a key consideration in both models. The EdgeStar includes a leakage sensor that automatically shuts off water flow if a leak is detected, protecting your home from water damage. The Whirlpool, while it does not explicitly mention a similar feature, includes a Sani Rinse option that sanitizes dishes by heating the final rinse. The EdgeStar's leak protection may provide additional peace of mind for homeowners concerned about potential water damage, making it a strong consideration in terms of safety features.
Brand Reputation and Sales Rank
Both models come from reputable brands, with EdgeStar holding a sales rank of 657 and Whirlpool at 874. While both brands are trusted in the market, the slightly higher sales rank of the EdgeStar may indicate a stronger performance in terms of customer preferences. However, brand reputation can vary based on individual experiences, so it may be beneficial to consider user reviews and testimonials alongside these ranks when making your decision.
Which should you buy?
In conclusion, the choice between the EdgeStar BIDW1802SS and the Whirlpool WDP540HAMZ largely depends on your specific needs. If you prioritize a lower price, larger capacity, and practical features for everyday use, the Whirlpool is the clear choice at $459.00. However, if you have limited space and desire a quieter operation with additional wash cycles, the EdgeStar, priced at $539.00, may be worth the investment. Ultimately, evaluating your kitchen space, washing needs, and budget will lead you to the right decision.
