For a front-loading horizontal-axis clothes washer, fill the clothes container to the highest point of contact between the door and the door gasket. If any portion of the door or gasket would occupy the measured volume space when the door is closed, exclude from the measurement the volume that the door or gasket portion would occupy.
For a front-loading horizontal-axis clothes washer with a concave door shape, include any additional volume above the plane defined by the highest point of contact between the door and the door gasket, if that area can be occupied by clothing during washer operation. For a top-loading horizontal-axis clothes washer, include any
additional volume above the plane of the door hinge that clothing could occupy during washer operation. Figure 3.1.4.2 of this appendix illustrates the maximum fill volumes for all horizontal-axis clothes washer types.

For all clothes washers, exclude any volume that cannot be occupied by the clothing load during operation.
3.1.5 Measure and record the weight of water, W, in pounds.
3.1.6 Calculate the clothes container capacity as follows:
C = W/d where:
C = Capacity in cubic feet liters.
W = Mass of water in pounds kilograms.
d = Density of water 62.0 lbs/ft3 for 100 F
993 kg/m3 for 37.8 C or 62.3 lbs/ft3 for 60 F 998 kg/m3 for 15.6 C.
3.1.7 Calculate the clothes container capacity, C, to the nearest 0.01 cubic foot for the purpose of determining test load sizes per Table 5.1 of this appendix and for all subsequent calculations that include the clothes container capacity.
3.2 Cycle settings.
3.2.1 Wash/rinse temperature selection.
For automatic clothes washers, set the wash/
rinse temperature selection control to obtain the desired wash/rinse temperature selection within the energy test cycle.
3.2.2 Wash time setting.

3.2.2.1 If the cycle under test offers a range of wash time settings, the wash time setting shall be the higher of either the minimum or 70 percent of the maximum wash time available for the wash cycle under test, regardless of the labeling of suggested dial locations. If 70 percent of the maximum wash time is not available on a dial with a discrete number of wash time settings, choose the next-highest setting greater than 70 percent.
3.2.2.2 If the clothes washer is equipped with an electromechanical dial or timer controlling wash time that rotates in both directions, reset the dial to the minimum wash time and then turn it in the direction of increasing wash time to reach the appropriate setting. If the appropriate setting is passed, return the dial to the minimum wash time and then turn in the direction of increasing wash time until the appropriate setting is reached.
3.2.3 Water fill level settings.
3.2.3.1 Clothes washers with manual water fill control system. For the large test load size, set the water fill level selector to the maximum water fill level setting available for the wash cycle under test. If the water fill level selector has two settings available for the wash cycle under test, for

the small test load size, select the minimum water fill level setting available for the wash cycle under test.
If the water fill level selector has more than two settings available for the wash cycle under test, for the small test load size, select the second-lowest water fill level setting.
3.2.3.2 Clothes washers with automatic water fill control system.
3.2.3.2.1 Not user-adjustable. The water level is automatically determined by the water fill control system.
3.2.3.2.2 User-adjustable. For the large test load size, set the water fill selector to the setting that uses the most water. For the small test load size, set the water fill selector to the setting that uses the least water.
3.2.3.3 Clothes washers with automatic water fill control system and alternate manual water fill control system. If a clothes washer with an automatic water fill control system allows user selection of manual controls as an alternative, test both manual and automatic modes and, for each mode, calculate the energy consumption HET, MET, and DET and water consumption QT values as set forth in section 4 of this appendix.
Then, calculate the average of the two values one from each mode, automatic and manual for each variable HET, MET, DET, and QT
