Abstract
An adjustable liquid temperature control system for a washing machine regulates the temperature of washing liquid established in a washing tub in an accurate and economical manner without the use of a dedicated temperature sensor. Preferably, numerous default mixing ratios for hot and cold fill water are preset in the washing machine. The system is designed to enable the washing machine operator to adjust one or more of the default mixing ratios in order to selectively fine tune the system. In accordance with one embodiment, the operator can directly input a desired mixing ratio. In another embodiment, the operator can indirectly establish a mixing ratio by entering a desired washing temperature.
