Overview of the Products

The EdgeStar BIDW1802SS and the SPT SD-6501W are two built-in dishwashers that cater to different kitchen needs and sizes. The EdgeStar model is an 18-inch wide unit designed for compact spaces, while the SPT model is a larger 24-inch option capable of accommodating more dishes. The EdgeStar is priced at $539.00, whereas the SPT is about 17% cheaper at $447.55. This price difference might influence consumers depending on their budget and space constraints.

Design and Build Quality

Both dishwashers feature modern designs, but they serve different purposes in terms of space. The EdgeStar BIDW1802SS, with its slim 18-inch width, is ideal for small kitchens or for replacing older appliances like trash compactors. In contrast, the SPT SD-6501W, at 24 inches, has a larger capacity, making it suitable for bigger families or households with more dishwashing needs. The SPT model also boasts a stainless steel interior, which contributes to its durability compared to the EdgeStar’s design.

Capacity and Place Settings

When it comes to capacity, the SPT SD-6501W has a clear advantage, accommodating up to 14 standard plate settings. This feature is particularly beneficial for larger households or those who entertain frequently. On the other hand, the EdgeStar BIDW1802SS can handle up to 8 place settings, which is more appropriate for smaller families or limited kitchen space. The difference in capacity may greatly affect the choice for users based on their specific dishwashing requirements.

Wash Programs and Efficiency

Efficiency is a crucial aspect of any dishwasher, and both models offer multiple wash programs. The EdgeStar BIDW1802SS includes six wash cycles: Heavy, Normal, ECO, Glass, Rapid, and Rinse, along with options for sanitize, hi-temp, and heated dry. Meanwhile, the SPT SD-6501W also features six wash programs: Heavy, Normal, Light, Eco, Glass, and Rinse. Both dishwashers are Energy Star certified, ensuring that they meet federal energy efficiency guidelines, which can lead to savings on utility bills over time.

Noise Level and Operation

Noise levels can be a significant factor for consumers, especially in open-concept homes. The EdgeStar BIDW1802SS operates at a quiet 52 dB, making it a suitable choice for those who require a peaceful environment while the dishwasher is running. The SPT SD-6501W, however, has a slightly higher noise level at 55 dB. While both models are relatively quiet compared to older dishwashers, the EdgeStar has a slight edge in terms of quieter operation.

Additional Features

Both dishwashers come equipped with features that enhance user experience. The EdgeStar BIDW1802SS includes a leakage sensor that automatically shuts off the water flow in case of a leak, providing peace of mind for homeowners. The SPT SD-6501W, on the other hand, includes a top cutlery rack, which allows for flat placement of fine utensils, preventing them from falling through a traditional silverware basket. Each model offers unique features that cater to different user preferences.

Maintenance and Care

Maintenance is an essential aspect of keeping any appliance running smoothly. The SPT SD-6501W includes an error alarm that displays fault codes, which can assist users in identifying issues quickly. It also has a rinse aid warning indicator that reminds users when to refill rinse aid, helping to maintain optimal washing performance. The EdgeStar BIDW1802SS does not specify similar features but does include a silverware basket and cup tray, which are standard for dishwashers in its class.

Which should you buy?

Choosing between the EdgeStar BIDW1802SS and the SPT SD-6501W ultimately depends on your household needs and kitchen space. If you have a smaller kitchen and require a compact dishwasher, the EdgeStar is a solid choice with its quiet operation and leak protection. However, for larger households needing greater capacity and efficiency, the SPT SD-6501W offers better value at a lower price and additional features like a top cutlery rack. Consider your specific requirements to make the best choice for your home.
