Diagnostic Codes
The Diagnostic Codes are identified when the
severity level of the abnormality detected is higher
and service may be required.
When a problem with the dryer is detected a
Diagnostic Code is assigned, and can be displayed.
The Control Board will not log multiple same codes
per cycle; however, it will log as many Diagnostics as
possible for the machine to continue running.
Access Diagnostic Codes by entering the Service
Mode and pressing Wrinkle Prevent. A d will be
displayed.
Rotate the Cycle Selector Knob in either direction to
step through the list of codes one code at a time.
Once an initial direction is selected by the user (either
Clockwise or Counterclockwise), subsequent movements
of the knob in the same direction will show older codes.
If the user changes direction and turns the knob in the
opposite direction, the more recent code will be
displayed.
WARNING
While a diagnostic code is displayed, if the
Start/Pause button in the center of the Rotary Cycle
Selector is pressed and held, the machine will display
the number of cycles ago the diagnostic code
occurred. When the Start/Pause button is released,
the diagnostic code is again displayed.
Clearing Diagnostic Codes
To clear the diagnostic code list press the Sensor
Dry Level and Time keypads together for 3 seconds
while viewing the list. The cycle count for each
diagnostic code will be reset to 0, but not the machine
