Diagnostic Codes:
The diagnostic/help code information displayed provides information about the machine. Any abnormalities monitored by the board will be identified as either a Help or Diagnostic code. Diagnostic Codes will be logged and stored in permanent memory (maximum nine in the list). A Diagnostic Code is logged when there is a problem with the system. It may be recommended the machine be serviced.
Software checks for open or shorted thermistors and door switch failures only during active cycles. Software continuously checks for stuck button conditions.
“Stuck Button” fault detection uses the lower dryer cycle count when logging a diagnostic code. Fault detection logs a code once after initially detecting a fault. A fault must clear before logging additional occurrences.
dL****Accessing Diagnostic Codes

Use the Time Adjust ^ (up arrow) and Time Adjust v (down arrow) buttons to step through the list. The display shows “End” after the last entry in the list is reached. Attempts to step past the beginning or end of the list cause the invalid selection chime to sound.
