On the covered Kenmore 665 model dishwasher, Sanitized LED blinks at end of cycle means Kenmore's service table lists this code as: control could not confirm Sanitation water temperature was achieved. Measure the incoming water temperature with a thermometer. Check that the supply is not hotter than 150 degrees.
Differential
Likely causes of “Kenmore 665 model dishwasher showing Sanitized LED blinks at end of cycle”, and how to tell them apart
- 1
Incoming water is below 120 degrees so the element cannot reach 150
What separates it The Sanitized LED blinks at the end of the cycle and the supply water is only warm
How to confirm Measure the incoming water temperature with a thermometer
- 2
Incoming water is above 150 degrees so the element shuts off before 10 minutes
What separates it The supply is very hot and the sanitation heating ends early
How to confirm Check that the supply is not hotter than 150 degrees
- 3
A damaged or failed heating element
What separates it The incoming water is normal and the LED still blinks
How to confirm Check the element for damage and see whether it heats
Before you touch a setting
Record this first — changing settings destroys the evidence
- That the Sanitized LED blinks at the end of the cycle
- The incoming water temperature at the dishwasher
- Whether the heating element looks damaged

0 of 4 completedCorrect only the documented fault domain
ReversibleThe heating element must stay on for 10 minutes when heating water for the sanitation cycle and water temperature must reach 150 degrees. Check incoming water temperature. If incoming water temperature is below 120 degrees, the heating element may not heat the water to 150 degrees. If incoming water temperature is above 150 degrees the heating element may not stay on for 10 minutes so the sanitation error may occur. If incoming water temperature is okay, check the heating element for damage. Replace the heating element if it's damaged or it doesn't heat. Parts named: heating element.
Check the incoming water temperature
ReversibleThe chart says the element must stay on for 10 minutes heating water for the sanitation cycle, and water temperature must reach 150 degrees.
Judge the supply against the two limits
ReversibleIf it is below 120 degrees the element may not reach 150. If it is above 150 the element may not stay on for 10 minutes, so the sanitation error can appear.
If the incoming water is okay, check the heating element
ReversibleReplace the heating element if it is damaged or does not heat. It is the only part the chart names.
