Troubleshooting
To avoid risk of electrical shock, personal injury or death; disconnect power before servicing, unless
testing requires power.
opposite direction, the more recent code will be
displayed.
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 cycle count.
