Thanks for counting on us to help with your appliance problem. My name is ***** ***** I look forward to helping you! The Er CO error means that there is a communication error between the electronics. This is a very broad and hard to diagnose error as it can be an issue with any connections at the control board or at any of the components. It can also indicate a board failure. I would start with removing each connector and reseating to alleviate any connection issues. If the error remains, replace the main control, available below.
