Abstract
In a dish washing machine according to the present invention, the contents of washing and rinsing are changed depending on dirt to prevent water from being uselessly used particularly if the degree of dirt on the dishes is low. Therefore, in the first drainage process in the latter part of the washing, the drainage is first started IS2-1). If 20 seconds have elapsed since the drainage was started, the drainage is stopped (S2-3). If the degree of dirt on the dishes is relatively high to select a sequence X (S2-4), drainage processing is performed on the basis of the contents of operations in the sequence X, after which the program proceeds to the rinsing process (S2-5 to S2-11). On the other hand, if the degree of dirt on the dishes is relatively low to select a sequence Y (S2-4), the program proceeds to the rinsing process without performing the processing in the steps S2-5 to S2-11 on the basis of the contents of operations in the sequence Y obtained by changing the contents of the operations in the sequence X.
