Abstract: An appliance having an enclosure arranged to receive articles to be treated also includes a water container and a steam chamber with a steam outlet. A water dispenser is arranged to dispense water from the water container to the steam chamber. A heating element is thermally associated with the steam chamber. A control is arranged to selectively operate the heating element. A steam path extends between the steam outlet and the enclosure. A chemical dispenser is positioned along the steam path. The heating element heats water in the steam chamber to create steam, and the chemical dispenser adds a chemical to the steam as the steam passes through the steam path.

Abstract: A control system for a washing machine having an aspirator connected to the discharge side of the inlet valve. The aspirator vacuum port provides a vacuum signal through a one-way valve to a vacuum reservoir which supplies a vacuum signal via a control valve to one or more vacuum responsive diaphragm actuators. The force output of the actuators is employed for auxiliary machine functions such as direct mechanical actuation of the drain valve or operating the recirculation pump motor start switch.
