Whirlpool Dishwasher Control Lock Light — What It Means & How to Fix It
Also shown as Lock Light Flashing, Control Lock on some models.
If the lock light flashes three times when you press a button, Control Lock is on — press and hold the Control Lock button for 3 seconds to unlock.
What this code means
Whirlpool says the light flashes three times if any button is pressed while the controls are locked. Holding the Control Lock button for three seconds unlocks them. If that does not work you may need to wake the dishwasher from Sleep Mode first by pressing Start/Resume or Cancel, or opening and closing the door.
The Control Lock button varies by model; see the control guide or owner's manual.
