Dimension comparison
Overview
When it comes to selecting a dishwasher, two compelling options are the Sharp SDW6736MS and the SPT SD-6501W. The Sharp model is priced at $579.00, while the SPT model is about 17% cheaper at $447.55. Both dishwashers are built to handle 14 place settings, making them suitable for medium to large households. However, they each offer unique features that cater to different needs and preferences.
Design and Build Quality
The Sharp SDW6736MS features a sleek stainless steel exterior that adds a modern touch to any kitchen. It also includes an adjustable third rack, enhancing its versatility for organizing flatware and serving utensils. In contrast, the SPT SD-6501W also boasts a stainless steel interior but comes with a traditional design that includes two pull-out dish racks. While both models feature stainless steel, the Sharp's third rack provides added convenience for users who often deal with a variety of utensils.
Noise Level
Noise can be a crucial factor in a dishwasher's performance, especially in open-concept homes. The Sharp SDW6736MS operates at a library-quiet 47 dBA, making it one of the quietest options available. In comparison, the SPT SD-6501W operates at a louder 55 dBA. If noise level is a priority, the Sharp model clearly has the advantage, delivering a more tranquil experience during operation.
Cleaning Performance
Cleaning performance is a vital aspect to consider when choosing a dishwasher. The Sharp SDW6736MS features a specialized Power Wash sprayer that enhances cleaning for heavily soiled pots and pans. It also has wash zones that allow users to efficiently clean smaller loads while reducing water and energy usage. The SPT SD-6501W, on the other hand, offers six wash programs—Heavy, Normal, Light, Eco, Glass, and Rinse—allowing for tailored cleaning based on the load. While the SPT model is versatile, the added features of the Sharp model may yield superior results for tough cleaning tasks.
Drying Efficiency
Both dishwashers include heated drying features, but they differ in performance. The Sharp SDW6736MS boasts advanced heated dry technology that ensures dishes emerge spotless and ready for use. The SPT SD-6501W also provides an active heated drying function, enhancing drying capabilities. However, the Sharp's superior drying performance may appeal to those who prioritize quick access to clean dishes without the need for towel drying.
Energy Efficiency
Energy efficiency is a significant consideration for eco-conscious consumers. Both dishwashers are Energy Star certified, meaning they meet or exceed federal guidelines for energy efficiency, which translates to long-term savings on energy bills. However, the SPT SD-6501W may have an edge with its tailored wash programs that help conserve resources, making it a potentially more economical choice in the long run.
User-Friendly Features
The Sharp SDW6736MS comes equipped with top-touch controls and six wash cycles, complemented by seven options to cater to different cleaning needs. This intuitive design makes it easy for users to customize their dishwashing experience. In contrast, the SPT SD-6501W includes a time delay feature that allows users to program operation for a later start time, along with an error alarm to display fault codes. Both models offer user-friendly features, but the Sharp’s range of options may provide a more customized experience.
Size and Capacity
Both models are designed to accommodate up to 14 standard plate settings, making them suitable for most households. The Sharp SDW6736MS has dimensions of 23-7/8" x 33-7/8" x 26-15/32", while the SPT SD-6501W is built for top-mount installation with a minimum cabinet cutout of 24" W x 24" D x 35" H. While both models can handle similar capacities, the Sharp’s adjustable third rack can facilitate better organization for users who have various sizes of dishware.
Which should you buy?
Choosing between the Sharp SDW6736MS and the SPT SD-6501W ultimately depends on your specific needs and preferences. If you prioritize a quiet operation, superior cleaning performance, and advanced features, the Sharp SDW6736MS is the better option despite its higher price of $579.00. On the other hand, if you are looking for a more budget-friendly choice that still offers solid performance, the SPT SD-6501W at $447.55 may suit you well, especially with its energy efficiency and user-friendly features.
