Covered Products

This category shall cover the various types of commercial dishwashers defined below.

Definitions

Dishwasher (or dishwashing machine): A cabinet-like appliance which, with the aid of water and detergent, is designed to wash and sanitize plates, glasses, cups, bowls, utensils, and trays by chemical, mechanical and/or electrical means and a sanitizing final rinse.

Under Counter Dishwasher: A machine with an overall height of 38 inches or less, in which a rack of dishes remains stationary within the machine while being subjected to sequential wash and rinse sprays, and is designed to be installed under food preparation workspaces. Under counter dishwashers can be either chemical or hot water sanitizing, with an internal booster heater for the latter. For purposes of this specification, only those machines designed for wash cycles of 10 minutes or less can qualify for ENERGY STAR®.

Stationary Rack, Single Tank, Door Type Dishwasher: A machine in which a rack of dishes remains stationary within the machine while subjected to sequential wash and rinse sprays. This definition also applies to machines in which the rack revolves on an axis during the wash and rinse cycles. Subcategories of stationary door type machines include: single and multiple wash tank, double rack, pot, pan and utensil washers, chemical dump type and hooded wash compartment (“hood type”). Stationary rack, single tank, door type models are covered by this specification and can be either chemical or hot water sanitizing, with an internal or external booster heater for the latter.

Single Tank Conveyor Dishwasher: A dishwashing machine that employs a conveyor or similar mechanism to carry dishes through a series of wash and rinse sprays within the machine. Specifically, a single tank conveyor machine has a tank for wash water followed by a final sanitizing rinse and does not have a pumped rinse tank. This type of machine may include a pre-washing section before the washing section. Single tank conveyor dishwashers can be either chemical or hot water sanitizing, with an internal or external booster heater for the latter.

Multiple Tank Conveyor Dishwasher: A conveyor type machine that has one or more tanks for wash water and one or more tanks for pumped rinse water, followed by a final sanitizing rinse. This type of machine may include one or more pre-washing sections before the washing section. Multiple tank conveyor dishwashers can be either chemical or hot water sanitizing, with an internal or external booster heater for the latter.

Hot Water Sanitizing (High Temp) Machine: A dishwashing machine that applies potable hot water to the surfaces of wares to achieve sanitization.

Chemical Sanitizing (Low Temp) Machine: A dishwashing machine that applies potable water and a chemical sanitizing solution to the surfaces of wares to achieve sanitization.

Standard Setting and Certifying Programs

Various national and international standards apply to electronic appliances. They are defined here as a guide:

ENERGY STAR® is a voluntary energy efficiency program sponsored by the U.S. Environmental Protection Agency. The ENERGY STAR® program makes identification of energy efficient appliances easy by labeling products that deliver the same or better performance as comparable models while using less energy and saving money. For additional information on the ENERGY STAR® program, including product specifications and a list of qualifying products, visit the ENERGY STAR® website at http://www.energystar.gov.

Restriction of Hazardous Substances (RoHS) Directive – A European Parliament and Council Directive restricts the use of certain hazardous substances in electrical and electronic equipment. It bans the placing on the EU market of new electrical and electronic equipment containing more than agreed levels of lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyl (PBB) and polybrominated diphenyl ether (PBDE) flame retardants. For additional information on RoHS please visit https://www.gov.uk/government/organisations/regulatory-delivery.

Specifications

Energy and Water Use:

All commercial dishwashers for which the United States Environmental Protection Agency and the United States Department of Energy have developed energy efficiency standards for compliance with the Energy Star program shall be ENERGY STAR® labeled and meet or exceed the ENERGY STAR® efficiency standard for commercial dishwashers. ENERGY STAR® qualified dishwashers use at least 41 percent less energy than the federal minimum standard for energy consumption and much less water than conventional models. This standard meets the requirements of Energy Law, Article 5, Section 5-108a and Executive Order No. 111.

Commercial dishwashers must meet the requirements provided in the table below to qualify as ENERGY STAR®. Machines designed to be interchangeable in the field from high temp to low temp, and vice versa, must be indicated as such on their Qualified Product Information (QPI) form and must meet both the high temp and low temp requirements below to qualify as ENERGY STAR®.

Energy and Water Efficiency Performance Qualifying models shall not exceed the energy and water consumption limits listed in the table below.
