Self Test Error Codes
The “Self Test” feature is intended for use by service personnel. If after performing a control panel self test (see
page 55) there were no errors detected, Code 0 is displayed, indicating that there were no problems and the test
was successful. If a problem is detected during the test, an error code is displayed upon completion of the test.
For example Code 3 would indicate a problem with the LEDs on the control panel. If multiple errors are detected,
multiple code numbers are displayed. For example, Codes 4, 2, 1, would indicate problems detected with the
buttons, LEDs, and the LCD backlight on the control panel.
The following lists the control panel self test error codes.
