What Control Light Flashing means

On JennAir dishwashers such as the JDTSS247HS or JDAF3924RX, the Control Lock light flashes three times when you press any button while the controls are locked. It is a setting, not a defect. Press and hold the Control Lock button for three seconds, depending on the model, to unlock. If that does not work, Sleep Mode may be on, and you can wake it by pressing Start/Resume or Cancel, or by opening and closing the door.

Common causes of Control Light Flashing

  • Control Lock enabled
  • Sleep Mode active
  • Button held for too short a time
✓ One safe check you can try

1. Press and hold the Control Lock button for three seconds. 2. If nothing happens, press Start/Resume or Cancel, or open and close the door to wake the control. 3. Then try the Control Lock hold again. 4. If the light still flashes and nothing responds, turn the breaker off for a minute and on, and call us if it persists.

! Why to stop there
  • A dead panel needs a test of the control.
  • Pressing random buttons can make things worse.
  • Moisture on the panel can mimic a lock.
  • We check the panel 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.

Control Light FlashingControl Light Flashing questions
Why does the light flash three times?

That is how the dishwasher tells you the controls are locked. Any button press is ignored and answered with three quick flashes, so nothing is wrong with the machine.

How long do I hold the button?

Hold the Control Lock button for three seconds. Some models differ slightly, so keep holding until the light stops flashing, then try a normal button to confirm it responds.

What if it keeps flashing?

Wake the control from Sleep Mode and try again. If the panel still ignores you, call us. We quote the repair in writing and cover it for 30 days.
