Abstract
In the tub of a clothes or dishes washing machine, the fluid temp. is brought to the required level by mixing two fluids of different temps. The tub is filled by successive and alternating charges from each of the two fluid supplies so that as the temp. drifts from the selected level in one direction, the next fluid charge is of a temp. to correct the temp. drift in the tub. The process gives a control system for the washing fluid temp., without requiring additional electric heating after the tub has been filled.
