Abstract
The present disclosure relates to a method of controlling a dishwasher. The method of controlling a dishwasher of the present disclosure includes steps of: detecting a temperature of air supplied to a tub through a heating duct by a temperature sensor; operating a supply fan which supplies outdoor air to the heating duct; operating a heater disposed in the heating duct; determining whether the supply fan and the heater are normally operating; and determining that the supply fan and the heater are normally operating, when a temperature change detected by the temperature sensor is within a first set range.
Claims9
A method of controlling a dishwasher including a tub defining a washing space, a supply fan configured to supply outdoor air to the tub, a heating duct configured to guide the outdoor air towards the tub, a heater configured to heat the outdoor air in the heating duct, and a temperature sensor configured to determine a temperature of the outdoor air from the heating duct, the method comprising:
- measuring, by the temperature sensor, a change of a temperature of air supplied to the tub through the heating duct;
- operating the supply fan configured to supply outdoor air to the heating duct;
- operating the heater disposed at the heating duct;
- determining, based on a slope value of the change of the temperature detected by the temperature sensor being within a first set range, that the supply fan and the heater are normally operating;
- and
- determining, based on the slope value of the change of the temperature detected by the temperature sensor being outside the first set range, at least one of a failure of the supply fan or a failure of the heater,
- wherein the failure of the supply fan and the failure of the heater are determined based on whether the slope value of the change of the temperature detected by the temperature sensor is within a second set range, wherein the second set range corresponds to temperature values lower than those of the first set range, and
- wherein the failure of the supply fan is determined based on the slope value of the change of the temperature detected by the temperature sensor being within the second set range.
