Abstract
A controller is associated with the detergent dispenser of a washing machine, such as a clothes washing machine or a combined clothes washing and drying machine. The controller selectively controls the addition of various detergents and rinsing aids into the machine's tub. The corresponding control position is signalled by a plurality of micro-switches (17, 18, 19, 20) that are actuated by a rotating compartment selector (15) of the dispenser. The selector selectively establishes communication between the cold or hot water supply and each one of the compartments of said dispenser. The micro-switches (17, 18, 19, 20) can be switched on or off, along with a corresponding operational component part (42, 43, 44, 45) of the machine, by the rotating compartment selector means (15). The closure of the micro-switches is reported to the electronic microprocessor controller (40) which therefore will identify the control position of the rotating compartment selector (15) and, as a consequence, the corresponding phase of the washing cycle being performed.
