Is the Control Lock on?
The control lock is used to avoid unintended use of the dishwasher as well as to avoid unintended cycle or option changes during a cycle. The control lock light will stay on for a short time, indicating that it is activated and all buttons are disabled. If any buttons are pressed while the dishwasher control is locked, the light will flash three times. The door can still be opened/closed while the controls are locked.
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 the control lock off.
To turn off the control lock feature:
Press and hold the designated control lock button for your model for 3 seconds. The location of the control lock button may vary depending on your model. Refer to the Use and Care Guide for the control lock button location for your model. The light will turn off and the control will be unlocked.
