No Short Program
It is easy to think that a shorter programme will cost less because the machine will only be on for a short period of time. It is not the case. Short programs use more energy because the machine automatically increases the temperature in order to compensate for the short washing time.
Drying
You use your dryer to dry laundry. Use a washing-machine that can produce excellent drying results. This will cause the washing machine to use more power, but it is also necessary for drying wet clothes. You want to save money? You can dry your laundry using a drying rack.
