A dishwasher that has a steam boiler containing hot water and steam under pressure. The dishwasher has a dishwashing and rinsing compartment with a body of hot water, adjustable as to depth, received in the bottom of the compartment. A time controlled device delivers steam from the boiler to steam jets in the compartment for a predetermined time period for washing the dishes. The steam jets have apparatus associated therewith that will cause the steam jets to periodically entrain hot water from the body of water to deliver a pulsating steam and hot water action against the dishes for washing them. The depth of the body of water can be raised so that only live steam and water will issue from the steam jets if desired, with no pulsating action. The time controlled device delivers hot rinse water from the boiler for rinsing the dishes in the compartment after the dishwashing operation.
