How to lower the cost of running a washing machine

The motor and pump in a washing machine use relatively little electricity: around 0.3–0.5 kWh per load for a cold wash. A hot wash with water from an electric water heater can push the total to 2 kWh or more per load. Front-loaders and high-efficiency top-loaders use less water and spin clothes drier, which also cuts dryer time.

  • Wash in cold water — modern detergents clean well, and it can cut energy per load by up to 90%.
  • Run full loads and use the high-spin setting to shorten drying time.
  • Use the eco cycle for lightly soiled clothes.
