Lock button is lite up and won't let be use dishwasher tried to hold the air dry button for 4 seconds like it says to unluck it but it won't unlock it. So now I can't use dishwaser at all. How do I reset the control panel

Unlock your Kenmore dishwasher control panel by pressing and holding the "Heated Dry" button for four seconds.

Press two buttons in quick succession. Press "Heated Dry," "Normal Wash," "Heated Dry" and "Normal Wash" to instruct your Kenmore dishwasher to run a short diagnostic test.
