Abstract
A drum-type washing machine that includes a program controller, a drum rotatably mounted in a detergent solution tub, a detergent solution discharge system disposed at a base of the detergent solution tub having a detergent solution drain pump, a sensor for determining a foam level and/or a negative time gradient of a liquid/air mixture contained in the detergent solution tub, a drive motor for the drum that adjusts a rotation of the drum to eliminate foam in the drum-type washing machine, and a water supply system that adds a small volume of water continuously or discontinuously if foam is detected by the sensor during the run-up to spin speed of the drum with the detergent solution drain pump switched on continuously or discontinuously.
