In this paper, we discuss the effects of water types and temperature in automatic washing machine. The automatic washing machines are being used in hard water areas void of useful results because machines could not detect the type of water. Hard water consumes more detergent and washing time for laundry. The proposition of the paper is that the soft water and high temperature should be used in washing machines, it will not only reduce the quantity of detergent but also have positive effects on economy and fabrics. In this way, energy and washing time can be saved. The results are verified by TOPSIS technique of MCDM. The pretending results and the actions of aforesaid device have been done by using MATLABs fuzzy logic toolbox. Logic Controller (FLC), TOPSIS technique, MCDM.

Water is a key factor in the success of the washing process. The hardness of water effects pH and pH determines the solubility. The results reveal that people living in hard water areas seldom use water softeners as compared to those living in soft water areas; the absolute percentage of people living in hard water areas and using water softener is quite low and they use more detergent. A limitation of the study is that it is based on self-reported water pH and not on actual analytical laboratory results of water tested for this property. On the other hand, an implication of the current research is that many consumers are aware of the adverse effect of pH on the outcome of the washing process and they apply various methods to neutralize this effect."
