1. A washing machine appliance, comprising:
a Venturi pump; an inlet conduit configured for directing a flow of liquid water to the Venturi pump; a valve configured for regulating the flow of liquid water through the inlet conduit; an outlet conduit configured for directing a flow of wash fluid out of the Venturi pump; an additive dispensing system comprising
a tank defining a volume, the volume of the tank configured for receipt of a fluid additive; andan additive conduit extending between the tank and the Venturi pump; a flow meter configured for measuring a flow of fluid additive through the additive conduit; and a controller in communication with the valve and the flow meter, the controller configured for
actuating the valve to an open configuration in order to initiate the flow of liquid water to the Venturi pump through the inlet conduit;monitoring a flow rate of fluid flowing through the additive conduit to the Venturi pump with the flow meter after said step of actuating;measuring a volume of fluid additive dispensed at the Venturi pump after the flow rate of fluid flowing through the additive conduit to the Venturi pump decreases by at least a predetermined amount during said step of monitoring; andoperating the valve to a closed configuration in order to hinder the flow of liquid water to the Venturi pump through the inlet conduit after a predetermined volume of fluid additive has been dispensed at the Venturi pump. |
