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.
