Size, Fit, and Control Differences
Installation width
The Kenmore 24-Inch Built-In Dishwasher measures 23.6 inches wide, fitting standard 24-inch cabinetry. The Kenmore 18-Inch Compact Built-In Dishwasher is narrower at 10 inches wide according to its specs, designed for tighter spaces. You must check your cabinet opening carefully. The 24-inch model requires a full-sized cutout, while the compact version suits smaller kitchens or apartments. Choose the width that matches your existing layout to avoid costly modifications.
Interior capacity
Both models feature the EasyFlex Third Rack and MoreSpace Adjustable Rack for flexible loading. The 24-inch unit has a height of 33.9 inches, offering more vertical space for tall pots. The compact model lists a height of 10 inches in its specs, which suggests a smaller interior volume. You can fit more dishes in the larger 24-inch version. If you cook for a large family, the extra space in the standard model handles bigger loads more easily.
Control location
The Kenmore 24-Inch Built-In Dishwasher uses top-mounted controls with a smooth, streamlined touch. This keeps the front panel clean and modern. The compact model does not list its control location in the provided data. You should verify the control style for the 18-inch unit before buying. Top-mounted controls are often preferred for ease of use without bending down. The 24-inch model offers a clear advantage here with its specified design.
Leak protection
The Kenmore 18-Inch Compact Built-In Dishwasher includes built-in Leak Detection that senses and drains excess water to prevent damage. This feature is explicitly mentioned in its quiet wash description. The 24-inch model does not list leak detection in its features or specs. If you are concerned about water damage in a tight space, the compact model provides an extra safety layer. The 24-inch model relies on standard installation for protection.
Noise level
Both dishwashers operate at 45 dBA, providing whisper-quiet performance. You can run either model during a conversation or while watching TV without disturbance. The 24-inch model offers a QuietWash option for even lower noise. The compact model highlights this quietness as a key benefit. Since the decibel rating is identical, neither model holds an edge in pure noise output. You get the same quiet experience from either choice.
Drying technology
Both units use TurboDry technology with a built-in fan and heating element. This system pulls moisture out and ensures plastics come out dry and spot-free. You do not need to use dish towels with either model. The cleaning and drying performance is identical based on the shared technology. Neither product has an advantage in drying capability. You can trust both to handle difficult loads with the same effective results.

You get the same SmartWash soil sensors and TurboDry fan as the larger unit. The black finish provides a sleek look for smaller kitchens or apartments.
Buyers prioritizing quiet operation and safety
Both units run at 45 dBA, but the compact model adds Leak Detection. This feature senses excess water and drains it automatically to prevent damage.
