Abstract
A method for monitoring a level of a sanitation agent in a dishwashing system having a sanitation agent supply vessel includes the step of providing a supply tube having a first portion and a second portion that are unconnected to one another. The first and second portions are linked with a pipe. An optical sensor is situated adjacent the pipe, and a reference reading, a fault check reading, and a fault confirmation reading is sequentially taken with the optical sensor. The method further includes the step of imposing a warning signal by a controller when both: (1) a magnitude of the difference between the reference reading and the fault check reading exceeds a threshold; and (2) a magnitude of the difference between the reference reading and the fault confirmation reading exceeds the threshold.
