1. An automated cleaning machine comprising:
a housing defining a wash chamber in which articles to be cleaned are subjected to a cleaning process;
a sump configured to receive and store a cleaning solution;
at least one processor;
at least one storage device that stores default values of cleaning process parameters including one or more of a wash time, a rinse temperature, and a rinse time;
the at least one storage device further comprising instructions executable by the at least one processor to:
control execution by the cleaning machine of at least an initial portion of the cleaning process using the default values of cleaning process parameters;
determine a first temperature of the cleaning solution in the sump at a first predetermined time during execution of the cleaning process;
determine a second temperature of the cleaning solution in the sump at a second predetermined time during execution of the cleaning process, wherein the second predetermined time is subsequent to the first predetermined time;
determine a sump temperature difference between the first temperature and the second temperature;
predict a number of heat unit equivalents (HUEs) that will be delivered during the cleaning process based on the sump temperature difference;
in response to the predicted number of HUEs not satisfying a target range indicative of thermal sanitization, adjust values one or more of the cleaning process parameters such that a revised predicted number of HUEs that will be delivered during the cleaning process based on the sump temperature difference satisfies the target range indicative of thermal sanitization; and
control execution of a remaining portion of the cleaning process using the adjusted values of the cleaning process parameters.
