Kenmore dishwasher

my dishwasher stopped santizing the dishes, it works fine, and the dishes are clean. but when cycle is over the sanitize light blinks, indicating the dishes have not been sanitized. any clue what could have happened?

a model number may be helpful, many people make d/w for Kenmore

If the heater is working for drying, then it could be a defective thermistor (temperature sensor)
