Abstract

A washing machine 1 contains water level sensors 3, 4 in a drum 2, which has a water inlet 10. A hot water supply 6 and a cold water supply 7 are connected respectively to the inlet 10. The operation of valves 11, 12 for disconnecting and connecting the supplies 6, 7 to the inlet 10 is governed by a processor 14, in accordance with the water temperature at the inlet 10, which is sensed by temperature sensor 13.
In another aspect of the invention, the processor 14 renders a door catch inoperable when the drum 2 is full of water, provides an indication to the user that the door catch has been rendered inoperable, and initiates a draining cycle to drain the water from the drum 2 before automatically opening the door.
