Abstract
A steam purge method for a dishwasher includes a washing cycle, a steam purge cycle and a rinse cycle. During the steam purge cycle, a dishwasher tub is filled with fluid to a level below a heating element in a wash chamber, heated and at least partially converted to steam in the wash chamber. After the steam purge cycle, the dishwasher is drained and the rinse cycle commences. Optionally, a heated drying cycle may be performed upon termination of the rinse cycle. A single heating element arranged in the wash chamber is utilized for heating washing fluid during each of washing, purging and steam generation cycles, as well as for the heated drying cycle.
