What Sanitize Light Flashing means

On JennAir dishwashers such as the JDTSS246GL or JDPSG244PS, a flashing Sanitize light means the dishwasher did not reach the temperature needed to sanitize. Your dishes were not sanitized. It is a message about the cycle result, not a breakdown. The water temperature should be at least 120 F (49 C), and an interrupted cycle can also cause it. Nothing is broken.

Common causes of Sanitize Light Flashing

  • Incoming hot water below 120 F (49 C)
  • Door opened during the sanitize cycle
  • Cycle interrupted before the sanitizing step finished
✓ One safe check you can try

1. Run the hot tap nearest the dishwasher for about 30 seconds and check that the water gets hot, at least 120 F (49 C). 2. Raise the water heater setting if needed, within safe limits. 3. Do not open the door during the cycle. 4. Rerun the sanitize cycle. If the light keeps flashing, call us.

! Why to stop there
  • Changing a water heater is its own job and can be a scald risk.
  • The dishwasher heater might be fine; the supply could be the cause.
  • Repeating the cycle without checking temperature wastes water.
  • We check supply temperature and the heater and quote in writing.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Sanitize Light FlashingSanitize Light Flashing questions
Are my dishes safe to use?

They were washed, but they were not sanitized. If sanitizing matters for that load, rerun the cycle once the water coming from the tap is hot enough, at least 120 F.

What temperature is needed?

The water reaching the dishwasher should be at least 120 F (49 C). Running the hot tap nearest the machine for about 30 seconds before you start helps the first fill arrive hot.

Could the door be the reason?

Yes. Opening the door mid-cycle can break the sanitize step. Let the cycle finish. If the light still flashes, call us and we will check the heater.
