Frigidaire 24 in Front Control Built-in Tall Tub vs SPT SD-6501W 24″-wide Built-In Stainless Steel
Updated July 2026 — full head-to-head comparison.
Overview of the Frigidaire and SPT Dishwashers
The Frigidaire 24 in Front Control Built-in Tall Tub Dishwasher is priced at $379.12, making it about 17% cheaper than the SPT SD-6501W, which retails for $447.55. Both dishwashers are designed to meet the needs of modern households, but they feature distinct functionalities and designs that might sway your decision based on your specific requirements.
Both products are built with durability in mind, featuring stainless steel construction. However, the Frigidaire may appeal to those looking for a simplified washing experience with its four wash cycles, while the SPT boasts a more extensive functionality with six wash programs. Understanding these differences is crucial as you choose the right dishwasher for your kitchen.
Design and Build Quality
The Frigidaire features a front control panel and a tall tub design that enhances its usability, especially in tight spaces. It allows for easy access to controls without having to bend down. In contrast, the SPT has a built-in top-mount design that is equally practical. Its stainless steel interior not only adds to the aesthetic appeal but also contributes to the durability of the unit.
While both models are designed to fit standard kitchen spaces, the SPT's dimensions and taller tub provide a capacity for up to 14 standard plate settings. This feature can be a significant advantage for larger households or frequent entertainers.
Washing Performance
When it comes to washing performance, the Frigidaire dishwasher employs DishSense Sensor Technology, which adjusts the wash cycle based on the soil level of the dishes. This technology can help improve cleaning efficiency. In comparison, the SPT offers six wash programs including Heavy, Normal, Light, Eco, Glass, and Rinse, catering to a broader range of washing needs.
The SPT also includes an error alarm that displays fault codes, which can be helpful for troubleshooting. This feature is absent in the Frigidaire, which may be a consideration if you value advanced diagnostics in your appliances.
Energy Efficiency
Energy efficiency is a critical factor for many consumers, and both the Frigidaire and SPT models meet or exceed federal guidelines for energy efficiency. However, the SPT specifically highlights its ENERGY STAR certification, indicating that it not only saves energy but also reduces costs on your utility bills over time.
With the Frigidaire priced lower, you might expect it to be less efficient; however, both dishwashers are designed to be economical. The SPT's efficiency claims might resonate more with environmentally conscious consumers who want to minimize their carbon footprint.
Drying Capability
The drying capabilities of both dishwashers differ significantly. The Frigidaire does not specify a heated drying option, which might mean that drying performance could vary based on environmental conditions. In contrast, the SPT includes a heated drying function that promises more effective drying of dishes, reducing the chances of water spots and ensuring that your dishes are ready to use immediately after the cycle ends.
This heated drying feature can be particularly advantageous in humid climates, where moisture can lead to less effective air drying.
Noise Level
Noise levels are an essential consideration, especially for open-concept homes. The SPT operates at 55 decibels, which is relatively quiet and should not disrupt conversations or activities in adjacent rooms. However, the Frigidaire does not provide specific noise level details, leaving potential buyers unsure about its operational sound.
For consumers who prioritize a quiet dishwasher, the SPT’s defined noise level gives it an edge in this category. It’s important to consider your kitchen layout and how sound travels in your living space when making a decision.
Capacity and Flexibility
In terms of capacity, both dishwashers can accommodate a substantial number of dishes, but the SPT stands out with its ability to hold up to 14 standard plate settings, making it a suitable choice for larger families or those who entertain frequently. Additionally, the SPT features a top cutlery rack that allows for flat placement of fine utensils, which can be a game-changer for keeping smaller items secure during the wash cycle.
The Frigidaire, while not specified for plate settings, still offers a tall tub design that provides flexibility in loading. However, if maximum capacity and specific loading configurations are critical for your household, the SPT is likely the better option.
Which should you buy?
Choosing between the Frigidaire 24 in Front Control Built-in Tall Tub Dishwasher and the SPT SD-6501W comes down to your specific needs and preferences. The Frigidaire is about 17% cheaper at $379.12, making it a budget-friendly option with essential features like DishSense Sensor Technology. On the other hand, the SPT offers more wash programs, a heated drying feature, and higher capacity, making it better suited for larger households or those who prioritize advanced functionality.
Consider what aspects are most important for your lifestyle—whether it's price, washing performance, drying efficiency, or noise level. Both dishwashers have their strengths, so the best choice ultimately depends on what fits best with your kitchen and washing habits.
