Abstract
A kitchen appliance includes a hot liquid generator, at least one heater, at least one temperature sensor, a discharge port in fluid communication with the hot liquid generator, a first pump, and a controller that actuates the at least one heater to heat liquid in the hot liquid generator, receives signals from the at least one temperature sensor and records an elapsed time in which liquid in the hot liquid generator is heated from a first temperature to a second temperature, calculates the volume of the liquid in the hot liquid generator based on the elapsed time and the first and second temperatures, and compares the calculated volume to a range of expected volumes. Depending on the comparison, the controller actuates the first pump to pump liquid out of the hot liquid generator to the discharge port or outputs an error signal.
