Abstract
A dishwashing machine having a gas-fired heater is provided with a flue structure having wall portions common to the tank and wash chamber of the machine. While the machine is running liquid splashes against these wall portions and exchanges heat therewith. When the water circulation system is stopped, the heater is limited to a standby condition which is predetermined to maintain these wall portions at substantially the same temperature as during running conditions.
