Abstract
A vent for a dishwasher provides a valve with dual actuation, either to be electrically actuated according to a cycle of the dishwasher so as to close during periods of high noise generation, typically the wash cycle, and opened during the dry cycle, or to be actuated independently of the cycle under pressure differences such as may be caused by interruption of the dishwasher cycle and opening and closing of the dishwasher door such as may cause a pressure surge as the introduced cool air is rapidly heated in the interior of the dishwasher.
