(o) Washing machines.

(1) Residential clothes washer means a consumer product designed to clean clothes, utilizing a water solution of soap and/or detergent and mechanical agitation or other movement.

(2) Commercial clothes washer means a soft-mounted front-loading or soft-mounted top-loading clothes washer that is designed for use in applications in which the occupants of more than one household will be using the washing machine, such as multi-family housing common areas, coin laundries and/or other commercial applications, and has a clothes container compartment which:

(i) for horizontal-axis clothes washers, is not more than 3.5 cubic feet; and

(ii) for vertical-axis clothes washers, is not more than 4.0 cubic feet.

(3) The minimum efficiency standards for residential and commercial clothes washers shall be the levels set forth in Table 5.16 of this section determined in accordance with the test procedures set forth in 10 Code of Federal Regulations (CFR) part 430, subpart B, appendix J1 (see section 506.6 of this Part).

Table 5.16

Minimum Energy Efficiency Standards: Residential and Commercial Clothes Washers

Minimum Modified Energy Factor^a	Maximum Water Factor^b
(ft3/kwh per cycle)	(gals/ft3)
1.80	7.5

^a Modified Energy Factor means the quotient of the cubic foot (or liter) capacity of the clothes container divided by the total clothes washer energy consumption per cycle, with such energy consumption expressed as the sum of the machine electrical energy consumption, the hot water energy consumption, and the energy required for removal of the remaining moisture in the wash load.

^b Water Factor means the quotient of the total weighted per-cycle water consumption divided by the capacity of the clothes washer.

(p) Dishwashers.

(1) Dishwasher means a consumer product, equal to or greater than 22 inches in exterior width, that is a cabinet-like appliance which with the aid of water and detergent, washes, rinses, and dries (when a drying process is included) dishware, glassware, eating utensils, and most cooking utensils by chemical, mechanical and/or electrical means and discharges to the plumbing drainage system.

^b Full load means full-load efficiency is measured at peak load conditions.

^c IPLV (integrated part load value) is a weighted average of efficiency measurements at various part-load conditions.
