Abstract
A washing machine for washing laundry may include a drum type washing machine having a tub, a drum, a water pressure and/or level sensor, an air flow path, a bubble detecting sensor, and a controller. The bubble detecting sensor may be along the air flow path of the tub in order to detect whether bubbles, suds or foam are generated within the tub and/or whether the bubbles, suds or foam exceed an acceptable amount. When the bubbles within the tub are detected and/or exceed the acceptable amount, the washing machine (e.g., the controller) may perform a preset or predetermined bubble removing course or procedure to remove or reduce the bubbles.
