Undercounter Dishwashers
Undercounter dishwashers are a compact and efficient warewashing solution for smaller commercial kitchens, cafés, bars, and coffee shops. Designed to fit neatly beneath countertops, these machines save valuable floor space while still delivering the high performance required in fast-paced foodservice environments. Despite their smaller footprint, they offer powerful cleaning capabilities that meet or exceed the sanitation standards set by most health departments.
These dishwashers are typically front-loading and function similarly to residential dishwashers but with faster cycle times and higher temperature settings. Most models can process anywhere from 20 to 40 racks per hour, depending on the wash cycle length and water temperature. That’s enough capacity to handle back-of-house demands during peak service periods. For added convenience, some units come with built-in booster heaters to ensure the correct sanitizing temperatures are achieved, even if your water supply isn’t hot enough on its own.
Undercounter commercial dishwashers are available in two main types: high-temperature and low-temperature. High-temp units use water heated to 180° Fahrenheit or more to sanitize dishes, which generally results in faster drying times and superior results for glassware and utensils. Low-temp models, on the other hand, sanitize using chemical solutions and operate at lower water temperatures, typically around 120° to 140° Fahrenheit. While they may be more energy-efficient, they require ongoing chemical use and are better suited for establishments that prioritize energy savings over rapid drying.
When choosing an undercounter dishwasher, consider your volume requirements and the types of items you'll be washing. Glass-intensive environments like bars or cafés may benefit from specialized glasswashers that provide gentler cycles and spotless rinses. For kitchens with space constraints or limited access to hot water, a model with a built-in booster or low-temp option may be more appropriate. Be sure to also check for features such as auto-cleaning cycles, digital displays, and stainless steel interiors for ease of maintenance and longevity.
Installation requirements vary by model, but most undercounter units require access to a water supply, drainage, and an electrical connection. Some high-temp models may require venting or hood systems to handle steam output. Always check local building codes and health regulations to ensure proper compliance before purchasing or installing any commercial dishwasher.
