Dishwasher and method of operation

摘要

A dishwasher includes an interior tub and a wash pump for pumping wash liquid to wash dishes located in the interior tub. A pump motor for driving the wash pump is regulated by a control unit that adjusts a spraying pressure of wash liquid. The method for operating a dishwasher includes sensing the degree to which wash liquid is soiled and regulating the speed of a pump motor for spraying wash liquid against the dishes, depending upon the degree to which the wash liquid is soiled. The regulation of the pump motor adjusts the wash liquid spraying pressure.
