ABSTRACT:
A dishwasher whose drying system works by condensation, having a washtub (3) in heat-exchange contact with a duct (8) that may be closed by a non-return valve and having a fan (14) suitable for causing a flow of cooling air to circulate. The dishwasher also includes a circulation pump (4) and a discharge pump (5), whose rotors are connected to the driveshaft (6) of a reversible motor (7), to pump water to their corresponding force ducts when the shaft is rotating in one direction or the other, respectively. The valve plug (15) is pneumatically switchable by the fan (14) between a closed position and an open position of the duct (8) when the shaft (6) rotates in one direction or the other, so that the flow of air circulates only when the discharge pump (5) is operating.
