Updated July 2026 — full head-to-head comparison.

Overview of the Frigidaire FDPH4316A and SPT SD-6501W Dishwashers

When comparing the Frigidaire FDPH4316A and the SPT SD-6501W dishwashers, the primary distinction lies in their pricing and feature sets. The Frigidaire is priced at $399.00, making it about 11% cheaper than the SPT at $447.55. Both dishwashers cater to households needing efficient cleaning for up to 14 place settings, but they offer different functionalities that may appeal to various consumer preferences.

Design and Build Quality

The Frigidaire FDPH4316A features a plastic tall tub, which is durable and easy to clean, while the SPT SD-6501W boasts a stainless steel interior that enhances durability and provides a modern aesthetic. The sleek top-control design of the Frigidaire contributes to a minimalist look with hidden controls, whereas the SPT’s tall tub design allows for more flexibility when loading larger dishes. This aesthetic difference may influence your choice based on kitchen decor and personal preference.

Wash Cycles and Programs

The Frigidaire FDPH4316A offers 4 wash cycles: Energy Saver, Heavy, Normal, and Quick, with a notable Quick Wash cycle that cleans dishes in just 60 minutes. In contrast, the SPT SD-6501W provides 6 wash programs, including Heavy, Normal, Light, Eco, Glass, and Rinse. This additional versatility could make the SPT a more appealing option for households with diverse dishwashing needs, although the Frigidaire's efficient Quick Wash feature stands out for those in a hurry.

Energy Efficiency

Both dishwashers are ENERGY STAR certified, meaning they meet or exceed federal guidelines for energy efficiency. The Frigidaire, priced lower, could result in significant savings on energy bills, especially considering its efficient design that saves water as well. While the SPT also promotes energy and money savings, its higher price point may offset some of those benefits in the short term.

Drying Performance

The Frigidaire FDPH4316A includes MaxDry™ technology for enhanced drying performance, which is essential for busy households. On the other hand, the SPT SD-6501W features a heated drying function that aims to provide efficient drying as well. While both models offer effective drying solutions, the Frigidaire’s advanced technology may give it a slight edge in ensuring dishes come out dry and ready to use.

Noise Levels

The noise levels of both dishwashers are not directly compared in the specifications. However, the SPT SD-6501W operates at a quieter 55 dBA, which can be a significant advantage for those who prefer a quieter appliance, especially in open-concept spaces. The Frigidaire does not specify its noise level, which may be a consideration for those in search of a quieter kitchen experience.

Customer Rankings and Popularity

In terms of sales rank, the Frigidaire FDPH4316A holds a better position at 1309, indicating its popularity among consumers. The SPT SD-6501W, with a sales rank of 5011, may not be as widely purchased, potentially reflecting differences in consumer preference or brand reputation. This popularity could suggest greater satisfaction among users of the Frigidaire model.

Which should you buy?

Ultimately, the choice between the Frigidaire FDPH4316A and the SPT SD-6501W depends on your specific needs and preferences. If you prioritize a lower price and quick washing capabilities, the Frigidaire at $399.00 stands out as a strong option. However, if you prefer a stainless steel interior, additional wash programs, and quieter operation, the SPT at $447.55 might be worth the investment. Consider your household’s dishwashing habits and aesthetic preferences to make the best choice for your kitchen.
