Energy Conservation Program: Test Procedure for Dishwashers (40 page(s), in English)

Notice of proposed rulemaking and request for comment - The U.S. Department of Energy ("DOE") proposes to amend the current test procedures appendix for dishwashers, adopt a new test procedure appendix, incorporate by reference newly published Association of Home Appliance Manufacturers ("AHAM") standards--AHAM DW-1-2020 and DW-2-2020--and apply certain provisions of the industry standards to to the test procedures appendices. The proposed amendments to the current procedure would establish requirements for water hardness, relative humidity, and loading pattern; update requirements for ambient temperature, detergent dosage, and standby power measurement; include testing approaches from recently published waivers for dishwashers; and include provisions for a minimum cleaning index threshold to validate the selected test cycle. The proposed new test procedure appendix would additionally include updated annual number of cycles and low-power mode hours for the calculation of energy consumption. DOE is seeking comments from interested parties on the proposal.
