Energy Conservation Program: Test Procedure for Dishwashers

In this final rule, the U.S. Department of Energy ("DOE") is adding clarifying instructions to the dishwasher test procedure regarding the allowable dosing options for each type of detergent; clarifying the existing detergent reporting requirements; and adding an enforcement provision for dishwashers to specify the detergent and dosing method that DOE would use for any enforcement testing of dishwasher models certified in accordance with the currently applicable dishwasher test procedure prior to July 17, 2023 (i.e., the date by which the dishwasher test procedure as amended by a final rule published on January 18, 2023 will be mandatory for product testing).
