||Manual and Mechanical Warewash
||Chlorine solution concentration
||Below 25 ppm
||At the in use mechanical dishwashing machine observed the residual chlorine concentration of the final rinse at 0 ppm. The sanitizer reservoir is full. However, the tubing is improperly routed. The tubes for the detergent and sanitizer are connected to the wrong reservoirs (five gallon container). The pic indicates the reservoirs are moved each evening during routine cleaning and in doing so were accidentally switched. During the inspection the pic routed the lines to the correct reservoir. After priming and cycling the machine functioned properly. The residual chlorine concentration of the final rinse was measured between 50 and 100 ppm. Item corrected.
