The lights flashing on the console when it will not respond to key presses normally indicates that you have a bad keypad control panel. The technical information for the key panel is shown in the first image below. The second image shows how to access the ribbon wire connector for this component. I recommend that you
shut off the breaker
for the dishwasher and access the wire harness connection between the control keypad and the electronic control board for the dishwasher. Check the ribbon cable to make sure that it is securely connected. Check it for damage. If it is plugged in properly and you see no damage, then you will likely need to replace the key panel. A technician would normally conduct a pin check on the keypad to verify this type of failure. If you have a volt/ohm meter with precision leads, you can check the keys (Pots/Pans and Normal) to see if they are stuck. There is a slight chance that the electronic control board is bad. If you do not want to conduct this advanced pin check of the control then you should be safe in replacing the keypad console to fix this problem.
You can order the console from the
website. Use the full model number of your dishwasher to order the correct console.
If you need more help, reply with additional details and the full model number of your dishwasher.
If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:
