What Blinking: Auto + Normal / Normal + Quick / Normal + Smart Auto / Smart Auto + Normal means

A pair of blinking lights that includes Normal reports that the dishwasher is too hot. The combinations are Auto with Normal, Normal with Quick, Normal with Smart Auto, or Smart Auto with Normal, and the names vary by model. These dishwashers have no digital display, and the same condition shows as HC on models that do. The control has found the temperature inside above its limit and stopped the cycle. The door may feel warm and the dishes unusually hot.

Common causes of Blinking: Auto + Normal / Normal + Quick / Normal + Smart Auto / Smart Auto + Normal

  • Temperature reading inside the tub
  • Heater staying on when it should switch off
  • Whether the lights return after a cool-down
✓ One safe check you can try

1. Switch the breaker off for 30 seconds, then back on. 2. Empty the dishwasher and let it cool. 3. Fill the detergent drawer. 4. Run a Normal cycle. 5. If the same lights blink again, stop using the dishwasher and call us.

! Why to stop there
  • A cool-down does not show whether the heater stays on or the reading is wrong.
  • We test the heating circuit and the sensing together.
  • The written price comes first, and a 30-day workmanship warranty follows the repair.
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.

Is an overheating dishwasher dangerous?

The control stops the cycle to prevent damage, but you should not keep running it. Let it cool and call us if it repeats. Please do not open the door in the middle of a cycle to check.

Is this different from the supply being too hot?

Yes. That is the incoming water. This pattern is about the temperature inside the dishwasher. Water that enters too hot and a hot tub need different checks.

Will resetting the breaker work?

One 30-second try is reasonable. If the same lights return, the heating or its sensing needs testing. Do not repeat it more than once, since heat is the concern.
