What Blinking: Heavy + Express 60 / Heavy + Quick+ means

A Samsung dishwasher without a digital display that blinks Heavy together with Express 60, or Heavy together with Quick+, is reporting that it is unable to heat. The light names depend on the model. The control looked for the water to warm and did not see it happen in the time allowed. Digital-display models show a related heater code. What you notice is a cycle that stops early, or dishes that come out cool with detergent residue.

Common causes of Blinking: Heavy + Express 60 / Heavy + Quick+

  • Heater not warming the water
  • Temperature reading not following the heater
  • Low water level during the heating stage
  • Heater wiring
✓ One safe check you can try

1. Turn the dishwasher off. 2. Check that the shutoff valve under the sink is fully open. 3. Empty it and fill the detergent drawer. 4. Run a Normal cycle. 5. If the same lights blink again, call us. Keep note of which pair of lights was flashing.

! Why to stop there
  • A good fill does not prove the heater is working.
  • We test the heater under power and check the temperature reading.
  • The written estimate is yours to approve first, with a 30-day warranty on workmanship.
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.

Blinking: Heavy + Express 60 / Heavy + Quick+Blinking: Heavy + Express 60 / Heavy + Quick+ questions
Is unable to heat the same as a stuck temperature sensor?

No. This says the water did not warm. A sensor problem is reported by a different light set. We test the heater first when the water does not warm.

Can low water cause it?

Yes, a low fill can stop the heater from working properly, so we check the water level too. Fill and heating work together, and a short fill upsets both.

Should I rerun the cycle?

Once is fine after the checks. If the lights return, stop and call us. Repeated restarts will not make the water warm if the heater cannot.
