Abstract
A dishwashing appliance includes a tub defining a wash chamber therein for receipt of articles for washing, a heating element, a sump positioned at a bottom of the wash chamber for receiving fluid from the wash chamber, a drain pump in communication with the sump, and a temperature sensor. Methods of operating the dishwashing appliance may include filling the sump with a liquid and heating the liquid by activating the heating element. Such methods also may include measuring a temperature of a liquid in the sump with the temperature sensor and comparing the measured temperature of the liquid to a minimum drain temperature threshold. Such methods may include draining the liquid from the sump after the measured temperature is equal to or greater than the minimum drain temperature threshold, such as immediately after heating the liquid.
