soil-sensing dishwashers without a truncated cycle option, and LF = the duration of the fan-only mode for the normal cycle for non-soil-sensing dishwashers; the average duration of the fan-only mode for sensor light response, sensor medium response, and sensor heavy response for soil-sensing dishwashers. Section 5.7, appendix C1.

Section 5.7 of AHAM DW12020
updated this calculation such that the combined low-power annual hours, SLP, is a calculated value for all units. That is, dishwashers that do not have a fanonly mode would use the same equation to calculate SLP as dishwashers that do have a fan-only mode. The only difference in calculation of SLP for units without a fan-only mode is that LF
would be equal to 0 for such units.
DOE proposes to reference the annual low-power mode energy consumption calculation specified in Section 5.7 of AHAM DW12020, which would also include the updated calculation method for combined low-power annual hours, SLP. This approach would change the hours assigned to low-power mode from 8,465 hours for dishwashers that do not have a fan-only mode to a value that is dependent on the duration of the normal cycle. Calculating the annual low-power mode energy consumption utilizing the measured active mode duration for each individual unit rather than assigning a constant value across all units would provide a more representative result.
The proposed change to the combined low-power annual hours would potentially impact the measured EAEU.
DOE also notes that the current energy conservation standard was developed using the method for determining the combined low-power annual hours specified in appendix C1. As such, DOE
proposes that, if this proposal were adopted, this change would go into effect in conjunction with any amended energy conservation standards for dishwashers. Accordingly, DOE is proposing that the updated calculation of annual low-power mode energy consumption be included only in the new appendix C2. Appendix C1 would continue using the current method for calculating the annual low-power mode energy consumption.
DOE requests comment on its proposal to use the updated combined low-power annual hours, specified in Section 5.7 of AHAM DW12020, for the calculation of annual combined lowpower mode energy consumption in the proposed new appendix C2.

consumption. DOE received two comments that recommended incorporating a network mode power consumption test method into appendix C1. Specifically, the Joint Commenters stated that DOE should consider incorporating a network mode power consumption measurement in the test procedure for connected dishwashers so consumers can have a better understanding of the energy associated with connected functionality, adding that as of September 2019, there were 11
ENERGY STAR-qualified connected models on the market. Joint Commenters, No. 8 at p. 2 Additionally, the CAIOUs recommended that DOE
define a network mode for smart dishwashers and implement a method to measure power consumption in network mode so that consumers have a better understanding of the power usage for connected units. CAIOUs, No.

DOE is aware of dishwashers with network capabilities that are currently on the market. However, DOE does not have sufficient data at this time regarding the energy use and consumer use patterns associated with such capabilities to evaluate potential test procedure provisions related to network capabilities. Therefore, DOE is proposing that all network functions must be disabled during testing.
Specifically, DOE proposes to include a requirement in appendix C1 and the proposed new appendix C2 that for dishwashers which can communicate through a network e.g., Bluetooth or internet connection, all network functions must be disabled, if it is possible to disable it by means provided in the manufacturers user manual, for the duration of testing. If the manufacturer instructions provided in the user manual do not provide for disabling a connected function, the standby power test procedure is conducted with the connected function in the as-shipped condition. DOE
seeks comment on its proposal to require the disablement of all network functions throughout the duration of testing.
DOE seeks the following information regarding connected dishwashers that could inform future test procedure considerations:
DOE requests feedback on connected dishwashers currently on the market.
Specifically, DOE requests input on the types of features or functionality enabled by connected dishwashers that exist on the market or that are under development.
DOE requests data on the percentage of users purchasing connected dishwashers, and, for those users, the

percentage of the time when the connected functionality of the dishwashers is used.
DOE requests data on the amount of additional or reduced energy use of connected dishwashers.
DOE requests data on the pattern of additional or reduced energy use of connected dishwashers; for example, whether it is constant, periodic, or triggered by the user.
DOE requests information on any existing testing protocols that account for connected features of dishwashers, as well as any testing protocols that may be under development within the industry.
J. Test Cycle Duration As stated, DOE established a separate product class for standard size dishwashers with a cycle time for the normal cycle of less than one hour from washing through drying. 10 CFR
430.32f1iii. See also 85 FR 68723.
The definition for the new product class of standard size dishwashers with a normal cycle time of 60 minutes or less defines normal cycle time by reference to Section 1.12 of appendix C1. 10 CFR 430.32f1iii. The new product class definition, as well as the previously established definitions for standard size dishwasher and compact size dishwasher, reference ANSI/AHAM
DW12010 for specifying the place settings used to distinguish between standard and compact. 10 CFR
430.32f1iiii.
On December 29, 2020, the National Resources Defense Council NRDC, Sierra Club, Consumer Federation of America, and Massachusetts Union of Public Housing Tenants petitioned the U.S. Court of Appeals for the Second Circuit to review and set aside the October 2020 Final Rule. Natural Resources Defense Council v. U.S. Dept of Energy, No. 204256 2d Cir.. On the same day, the States of California, Connecticut, Illinois, Maine, Michigan, Minnesota, New Jersey, New Mexico, New York, Nevada, Oregon, Vermont, and Washington, the Commonwealth of Massachusetts, the District of Columbia, and the City of New York filed a separate petition for review of the October 2020 Final Rule in the U.S.
Court of Appeals for the Second Circuit.
California v. U.S. Dept of Energy, No.
204285 2d Cir.. These two cases have been consolidated in the Second Circuit and have been placed in abeyance pending DOEs review of the October 2020 Final Rule in compliance with Executive Order 13990.
Further, on March 1, 2021, AHAM
petitioned DOE to reconsider the October 2020 Final Rule that established
