Is the Control Locked Light On or Flashing?
If the Control Lock feature has been enabled, the Control Lock light will flash 3 times indicating that it is activated. To turn off Control Lock, press and hold the Options key that says "Control Lock Hold 3 Sec" under it for 3 seconds. If the dishwasher has a dedicated Control Lock button in the Options selections, press and hold CONTROL LOCK for 3 seconds.
NOTE: You may need to disable Sleep Mode by pressing either Start/Resume or Cancel, or by opening and closing the door before you are able to turn Control Lock off.
NOTE: If your model requires you to press and hold PROSCRUB UPPER, 4 HOUR DELAY or BOTTLE WASH to lock the controls, the Control Lock light will be on when Control Lock is active.
Cycle power to the control to reset the dishwasher:
Much like a computer, resetting the dishwasher control can sometimes solve the issues you are experiencing. To reset the dishwasher control panel, it needs to be disconnected from the power source for one minute. If your dishwasher is plugged into an outlet, simply unplug the unit for one minute and then plug the unit back in. If the dishwasher is hard wired to the power supply, turn the breaker off at the home electrical panel that powers the dishwasher for one minute and then turn the breaker back on.
