1) Always wait until full load before washing or drying – two half-loads use more energy than a single load.
2) After washing has completed, switch off the machine as the machine will still be using electricity if any display light is on.
3) Wash clothes at 30°C, rather than warmer temperatures. This saves electricity and will not compromise cleaning performance. (It's been said that lower temperatures may cause mould build-up! See maintenance tips here.)
4) Use the high-spin speed on your washer – it dries your laundry, so you will use lesser electricity with the tumble dryer

5) Use dryers with sensors which detect the moisture level of the laundry, and dry clothes of similar fabric together, so as to have equal heat distribution. Both will prevent over-drying and and over-consumption of energy.
6) Place the tumble dryer in a well-ventilated room to prevent tumble dryer from over-heating
7) Washers with load sensors will help you determine the optimum time and water level and detergent required for the wash; this ensures you do not use up the three factors more than you need to!
