Customer Questions and Answers for Panel- Con by Whirlpool

Hello Robert, This is what I found in the use and care guide: Control Lock Option (select models) The control touchpads can be locked to prevent unwanted use. If this feature is activated between cycles, the dishwasher cannot be operated until the controls are unlocked. If desired, the controls can be locked after a cycle or delay has started. Setting the Control Lock: 1. Press the Heated Dry pad for three seconds. 2. An indicator light next to the lock graphic will illuminate when the controls are locked. To Cancel: 1. Press the Heated Dry pad for three seconds. 2. The indicator light will go off. If this isn't working for you, it's either going to be a bad control panel 6-919844, (a failed button), or the control board has gone into failure.
