PROBLEM TO BE SOLVED: To enable the shortening of required washing time, the lowering of drain noises and the realization of diversified operation patterns. SOLUTION: A washing pump to deliver washing water to housed dishes and a drain pump to discharge the washing water outside the machine develop individual pumping functions according to the normal or reverse rotation of one pump motor. In the washing operation of a washing process, in the rinsing operation of twice rinsing processes and in the heated rinsing operation of the heated ringing process, a washing pump (pump motor) is operated at the number of revolutions of 3,500 rpm. During the draining operation and the water supply/discharge periods in the respective processes, a drain pump (pump motor) is operated at the number of revolutions of 2,500 rpm.
