Overview of the Dishwashers

When comparing the EdgeStar BIDW1802SS and the Frigidaire FDSH4501A, the most immediate difference is their price and capacity. The EdgeStar BIDW1802SS is priced at $539.00, while the Frigidaire FDSH4501A comes in slightly higher at $579.00, making the EdgeStar about 7% cheaper. Additionally, the EdgeStar accommodates up to eight place settings, while the Frigidaire can hold up to 14, indicating a significant difference in capacity that may influence your buying decision.

Cleaning Performance

Both dishwashers offer impressive cleaning capabilities, but they employ different technologies. The EdgeStar BIDW1802SS features six wash cycles, including Heavy and ECO options, and has a sanitize feature that ensures hygienic cleaning. On the other hand, the Frigidaire FDSH4501A utilizes an EvenDry fan-assisted system along with a BladeSpray arm, ensuring a thorough wash and spot-free drying. If drying performance is a priority, the Frigidaire's EvenDry system could make it the better option.

Noise Levels

Noise levels are an important consideration for many buyers, and here the Frigidaire FDSH4501A has the edge. Operating at a quiet 49 dB, it is designed to be less disruptive during use. In contrast, the EdgeStar BIDW1802SS operates at 52 dB, which is still relatively quiet but may be slightly more noticeable, especially in open-concept living spaces. If a quieter operation is essential for your household, the Frigidaire may be the more suitable choice.

Energy Efficiency

Energy efficiency is a crucial factor in modern appliances, and both models boast ENERGY STAR certification, indicating they meet strict energy efficiency guidelines. However, the specific energy consumption rates are not provided, making it difficult to compare their efficiency directly on that front. The Frigidaire's mention of being energy-smart along with its larger capacity suggests it may provide better efficiency when fully loaded compared to the EdgeStar, especially in households with higher dishwashing needs.

Design and Dimensions

In terms of design, the EdgeStar BIDW1802SS is notably compact with dimensions of 17.75 inches wide, making it an excellent choice for smaller kitchens or as a replacement for older appliances like trash compactors. The Frigidaire FDSH4501A, being 24 inches wide, offers a more spacious interior but requires more kitchen space. The choice between these two will largely depend on your kitchen layout and available space.

User-Friendliness

User-friendliness is highlighted in both models, but they cater to different preferences. The EdgeStar BIDW1802SS includes a silverware basket and cup tray, which are thoughtful additions for organizing utensils. Conversely, the Frigidaire FDSH4501A features a three-level rack system, which allows for better organization of various dish sizes and types. If you prioritize versatility in loading and unloading, the Frigidaire's design may enhance your experience.

Sales Rank and Popularity

Popularity can often indicate consumer satisfaction, and the sales ranks of these dishwashers reflect their market performance. The EdgeStar BIDW1802SS has a sales rank of 657, while the Frigidaire FDSH4501A has a rank of 1623. The higher sales rank of the EdgeStar suggests it may be favored by consumers, potentially due to its price point and compact design, making it a popular choice for those with limited space.

Which should you buy?

In conclusion, choosing between the EdgeStar BIDW1802SS and the Frigidaire FDSH4501A largely depends on your specific needs. If you require a compact dishwasher that is about 7% cheaper and can efficiently handle up to eight place settings, the EdgeStar is a suitable option. However, if you prioritize larger capacity, quieter operation, and advanced drying capabilities, the Frigidaire may be worth the additional $40. Ultimately, your decision should be based on your kitchen space, dishwashing frequency, and preference for specific features.
