Sanitized LED Off — GE Dishwasher Sanitized Light Off / Not Sanitized

When a sanitize cycle finishes and the 'Sanitized' indicator does NOT illuminate, the dishwasher could not reach or maintain the final-rinse water temperature (about 150°F) required to certify the sanitize cycle to GE's residential sanitization (NSF) requirements. The dishes were still washed, but the sanitization claim could not be met for that cycle.
