Hello, I'm Joel and will be glad to help you today.

That error means there is a communication error between the user interface board and the main control board.

Try killing power at the breaker for a few minutes and then restore power and see if it will reset and work properly if not you will need to replace the main board.

Part #: 12006843 - click here

Here are the instructions to access the board and replace it, before replacing it check all the wires and make sure they all look ok as it could be a wiring issue from you spilling the grease.
