Hello Vanessa, thanks for your submission!
I understand that you are unable to operate your Electrolux dishwasher and the lock symbol on your control panel is on. This means that your dishwasher control has been locked and you would need to disable it in order to start the dishwasher. If you could provide me with your model number I can explain how to disable the control lock. You can locate the serial tag (which lists your model number) on the inside left hand wall of the dishwasher. With that information I can assist you further. -Matt
