Claim 17:
18. A method for controlling the initiation of a cleaning process for an interior of an appliance, the method comprising:
receiving sensor data from a detection sensor representative of a first time, the first time being a time when no cleaning product is present within a field of detection (FOD) of the detection sensor, wherein
the FOD of the detection sensor comprises one or more pre-determined locations in the interior of the appliance, each pre-determined location intended for the receipt of the cleaning product used during the cleaning process;

generating an initial condition based on the received detection sensor data representative of the first time;
receiving sensor data from the detection sensor representative of a second time, different than the first time;
generating a new condition based on the received detection sensor data representative of the second time; and
determining if cleaning product is present at the one or more pre-determined locations at the second time based on the comparison of the initial condition and the new condition.
