Whirlpool dishwasher lock light

On my quiet partner ll dishwasher the light under the lock symbol stays lit and the dishwasher won’t start when you hit any button, the light blinks three times then stays on. Any help please?

A model number may help others help you.

If you do not have the operators manual, go to the Whirlpool appliance site and under Support/Manuals download it.
It should have info on how to turn the lock feature off.

When checking the door for the model, it says how to unlock. Thanks for the help!
