Abstract
A dish washing machine according to the present invention carries out, in a kitchen detergent course, a soaking step for spraying a wash water stored in a containing tank toward dishes and leaving the dishes for a predetermined time precedent to a washing step. In the soaking step, a low temperature soaking is carried out in which the wash water in a washing tank is kept at about 30° C. (temperature appropriate for removing soils containing protein ingredients with a kitchen detergent, especially a neutral detergent), and thereafter a high temperature soaking is carried out in which the wash water in the washing tank is kept at about 50° C. Thereby, the soils containing protein ingredients attached to the dishes can be well removed away with the kitchen detergent.
