Abstract

A controller (1) for an automatic washing machine. The controller comprises a logic control circuit (2) connected to a central processing unit (CPU) (3) and to an electronic on/off switch (4) which in turn is connected to a power supply (not shown). The central processing unit is further connected to a water inlet valve (5), a drain valve (6), a motor/clutch drive (7), a water level sensor (8) and a wash load sensor (9). The controller further comprises a water inflow sensor (10) located in the proximity of the water inlet valve and connected to the central processing unit. The central processing unit is further connected to the power on/off switch.
