What do the efficiency metrics stand for?
Clothes washers Modified Energy Factor or MEF, is a combination of Energy Factor and Remaining Moisture Content (RMC). MEF measures energy consumption of the total laundry cycle (washing and drying). It indicates how many cubic feet of laundry can be washed and dried with one kWh of electricity; the higher the number, the greater the efficiency. Water Factor or WF is the number of gallons needed for each cubic foot of laundry. A lower number indicates lower consumption and more efficient use of water. Dishwashers Energy Factor or EF is the dishwasher energy performance metric. EF is expressed in cycles per kilowatt-hours (kWh) and is the reciprocal of the sum of the machine electrical energy per cycle plus the water heating energy consumption per cycle. Annual kilowatt-hour consumption is the number of kWh (energy) a dishwasher consumes in a year, assuming 215 cycles annually plus an allowance of 1 Watt of standby power (i.e., power drawn when a dishwasher is not actively running).
