E. Issues on Which DOE Seeks Comment
khammond on DSKJM1Z7X2PROD with PROPOSALS2

Although DOE welcomes comments on any aspect of this proposal, DOE is particularly interested in receiving comments and views of interested parties concerning the following issues:
1 DOE requests comment on its proposal to incorporate by reference into 10 CFR part 430 the most recent version of the industry standard for dishwasher energy and water use measurement, AHAM DW12020, as well as the industry performance standard, AHAM DW22020, both with modifications. DOE seeks comment on its preliminary conclusion that the proposed modifications to the industry standards are necessary so that the DOE test method satisfies the requirements of EPCA.
2 DOE requests comment on its proposal to require use of the water hardness requirements from Section 2.11 of AHAM
DW12020.
3 DOE requests comment on its proposal to reference AHAM DW12020 for the relative humidity and associated instrumentation requirements, which specifies a relative humidity test condition of 35 percent 15 percent, and a resolution of at least 1 percent relative humidity and an accuracy of at least 6 percent relative humidity over the temperature range of 75 F
5 F for the relative humidity measuring device. To the extent that stakeholder have additional information, DOE requests data regarding the impact of relative humidity on dishwasher energy and water usage.
4 DOE requests input on its proposal to specify a target nominal ambient temperature

of 75 F for active mode testing, as referenced from AHAM DW12020.
5 DOE requests comment on its proposal to reference in appendix C1 and the new appendix C2 the testing provisions from AHAM DW12020 to address the Miele waiver for dishwashers that operate at 208volts.
6 DOE requests comment on its proposal to incorporate the requirements of the CNA
waiver for any dishwasher with a built-in reservoir. In particular, DOE requests stakeholder feedback on using the detergent dosage requirement based on number of place settings rather than main wash water volume in the new appendix C2, for dishwashers with built-in reservoirs.
7 DOE requests comment on its proposal to incorporate into appendix C1 and the new appendix C2 the installation requirements for in-sink dishwashers from the FOTILE waiver.
8 DOE requests comment on its proposal that the detergent must be placed directly into the dishwasher chamber for any dishwasher that does not have a prewash or main wash detergent compartment.
9 DOE requests input on its proposal to update the estimated number of annual cycles from 215 to 184 cycles per year for future calculations of EAEU. DOE also requests comment on its approach to propose a new appendix C2 with the updated annual number of cycles, the use of which would be required for compliance with any amended energy conservation standards.
10 DOE requests comment on specifying that the test load items be as specified in AHAM DW12020 which references Section 3.4 of AHAM DW22020, while additionally retaining, as an alternative, the current test load specifications in appendix C1 and the new appendix C2.
11 DOE continues to request feedback and data regarding soiling level and whether there have been changes to consumers prerinsing behavior. DOE also seeks information regarding the impact of different soil levels on energy and water use in dishwashers currently on the market.
12 DOE requests comment on its proposal to remove the soil substitution and soil preparation requirements from Sections 2.7.4
and 2.7.5 of appendix C1 and apply these same requirements from AHAM DW12020
instead. DOE particularly requests data and information on how the proposed soil composition would affect energy and water use in current dishwashers.
13 DOE requests input on its proposal to use the loading requirements specified in Section 2.6.3.4 of AHAM DW12020.
14 DOE requests comment on its proposal to adopt in appendix C1 the new detergent and new dosage requirements as specified in AHAM DW12020, while also retaining the current detergent and dosage requirements in appendix C1. The use of either set of detergent requirements would be allowable for testing under appendix C1. DOE also requests comment on the detergent currently being used by manufacturers and test laboratories for testing and certification of dishwashers.
15 DOE also welcomes comments and data on the impact of the new detergent and dosage on energy and water use.

16 DOE requests comment on its proposal to reference in appendix C1 and the new appendix C2 the testing provisions from AHAM DW12020 to address the Whirlpool waiver for water re-use system dishwashers.
17 DOE requests feedback on the proposed methodology to test, score, and calculate a cleaning index to validate the tested cycle and seeks comment if other methodologies should be considered for validating the cleaning performance of the tested cycle.
18 DOE requests feedback on whether it should consider referencing Section 5.12.3.1
of AHAM DW22020 to measure cleaning performance, which would calculate the cleaning index based on soil particles only.
DOE notes that if it were to calculate cleaning index using soil particles only, it would reevaluate the per-cycle cleaning index threshold value to reflect this change.
19 DOE requests feedback on the proposed cleaning index threshold value of 65 for each test cycle or whether it should consider a threshold value of 70 instead.
20 DOE requests additional data on consumer dishwasher cycle selections. In particular, DOE requests data indicating the frequency with which consumers select the normal cycle; and, for cycles not conducted on the normal cycle, the frequency with which a more energy-intensive cycle is selected.
21 DOE also requests additional data on how frequently consumers are dissatisfied with the cleaning performance of the normal cycle as well as the actions, and the frequency of each action, that consumers would take if the load is not satisfactorily clean.
22 DOE requests feedback on its proposed approach to ensure that the test procedure produces test results which measure energy use and water use during a representative average use cycle.
23 DOE requests comment on its proposal that, if a test cycle at a particular soil level is re-tested using the most energy-intensive cycle, the filter should be cleaned prior to testing the soil level at the most energyintensive cycle.
24 DOE requests feedback on its proposal to require testing non-soil-sensing dishwashers using a soiled load for the purpose of being able to evaluate the cleaning index of each tested cycle.
25 DOE requests comment on its proposed approach for non-soil-sensing dishwashers; particularly that if a tested soil load meets the defined threshold criteria when tested on the normal cycle, no additional testing is required of cycles with lesser soil loads.
26 DOE requests comment and data on the test cycles currently selected by manufacturers for rating the energy and water use of dishwashers compared to the test cycles that would be selected under the proposed cleaning index threshold of 65 as a condition for a valid test cycle. In particular, DOE requests data on the extent to which manufacturers would need to test a more-energy intensive cycle, or redefine the normal cycle, to meet the proposed cleaning index threshold of 65.
27 DOE requests information on other potential methods to validate that the
