The machine energy (Equation 19) includes the energy consumed by all the physical processes necessary to run a load of dishes (e.g. pumps, heating element for drying cycle).
ME = LE x Loadsweek x 52 Equation 19
LE = load energy (kWh/load)
Loadsweek = dishwasher loads/week
52 = weeks/year
Machine energy for dishwashers is assumed to be 0.78 kWh/load for the purposes of this model (US DOE 1990, Page 3-8 table 3.4).
