The first practice in troubleshooting “Revolving Messages” is press the CLEAR button 3 times to remove old invalid messages. When a message is generated, it will continue to be present even if the error has internally corrected. This is by design to inform the user that there is/was a controller incident.
Note: When the term “CLEAN” is stated below, power down the controller and use a soft toothbrush and alcohol to gently break away deposits.
