SPT vs EdgeStar Spec Comparison
Installation type
The SPT SD-2225DWA is a countertop dishwasher. It sits on your counter and requires no permanent plumbing. This makes it ideal for apartments, offices, or small kitchens where you cannot cut into cabinetry. The EdgeStar BIDW1802SS is a built-in unit. It fits into a standard 18-inch cabinet cutout. You must install it under a counter. This option saves counter space but requires more complex setup. Choose the SPT for flexibility. Choose the EdgeStar for a permanent, integrated look.
Capacity
You need to know how many dishes each unit holds. The SPT model accommodates up to six standard place settings. It handles dishware up to 10.25 inches in diameter. The EdgeStar model holds eight place settings. It includes a silverware basket and a cup tray for better organization. The EdgeStar handles larger loads of dirty dishes. The SPT is sufficient for one or two people. If you cook for a family, the EdgeStar capacity is the clear winner here.
Wash cycles
Cycle variety matters for different levels of dirt. The EdgeStar offers six wash cycles: Heavy, Normal, ECO, Glass, Rapid, and Rinse. It also provides three options: Sanitize, Hi Temp, and Heated Dry. This gives you control over temperature and drying. The SPT listing does not specify the number of cycles. It mentions Energy Star certification and a delay start feature. You likely have fewer washing program choices with the SPT. The EdgeStar provides more tailored cleaning options for various dish types.
Width
Width determines where the unit fits in your kitchen. The SPT is 22 inches wide. It requires a significant amount of counter space. The EdgeStar is 18 inches wide. It is designed to replace older appliances like trash compactors. The EdgeStar is narrower, making it easier to fit in smaller cabinet spaces. The SPT is wider and bulkier. If you have limited counter space, the SPT might be too large. The EdgeStar width is more standard for built-in replacements.
Noise level
Noise can be a major factor in open-plan homes. The EdgeStar operates at 52 dB. This is a quiet level for a dishwasher. It keeps disturbance to a minimum during use. The SPT data does not list a decibel rating. You cannot compare the noise performance directly from the specs. The EdgeStar has a documented quiet operation. The SPT noise level remains unknown. If you are sensitive to sound, the EdgeStar provides verified quiet performance.
Safety features
Water damage protection is important for any appliance. The EdgeStar includes a leakage sensor. It automatically shuts off water flow when a leak is detected. This protects your home from water damage. The SPT listing does not mention a leak sensor or similar safety feature. You have no information on how the SPT handles leaks. The EdgeStar offers an active safety mechanism. This is a significant advantage for peace of mind during operation.
