The washing machine water flow contract valve comprises a housing (1) containing a poppet (4) which is controlled by a thermoactuator kinematically connected to a stem (4a) of the poppet. The stem (4a) is associated with a shaped leaf-spring (8), actuated by a plunger (7) projecting from a casing (6) containing a wax with high thermal dilative properties. The casing (6) is in contact with at least one thermistor (PTC) (9) powered via terminals (10) connected to the washing machine timer. - When the thermistor(9) is energised, the the wax in the casing (6) expands urging the axial movement of the plunger (7), the spring (8), and the popper (4) of the valve, which retracts from its seat (5),and thus the valve is opened to allow water to enter the washing machine tub. The thermoactuator assembly may be housed in a detachable housing part (1a).
