SERVICE DIAGNOSTICS
This mode is used to identify the root cause of an issue by isolating each
component. Use the 'Left' and 'Right' navigation keys to find the desired
function and use the 'Select/Enter' key to active or enter that function.
NOTE: Some features are not available on all models. Therefore the
machine will not respond to some features. Please reference the Use and
Care Guide for a list of available features for the specific model.
HMI Test
This mode tests various functions of the HMI. The expected behaviors of
each are described below.
Key Test: Use the instructions provided on the display to test each of the
available keys. To exit this mode, press and hold any key for 3 seconds.
LED Test: Use the instructions provided on the display to test the LED at
levels of On, 50%, and Off.
Display Test: Display will show a sequence of colors and patterns on
repeat.

components. Navigate to this screen through Service Mode and Service
Diagnostic Mode. Any faults that may occur during these activations may
or may not appear on the display but will be recorded in the 'Fault History'
section. A list of the expected behaviors for each component activation is
shown in Component Activation Function Chart.
Sensor Feed
back
Use the Sensor Feedback mode to selectively test various sensors. This
mode will display real time output values as the sensor measurements
change. Navigate to this screen through Service Mode and Service
Diagnostics. Any faults that may occur during these activations may or
may not appear on the display but will be recorded in the 'Fault History'
section. A list of the expected behaviors for each sensor feedback is shown
in Sensor Feedback Function Chart.
Diagnostic Cycle
Activation of the diagnostic cycle will automatically run a sequence of
component activations. The behavior is outlined in the Diagnostic Cycle
Chart. The lid must remain closed for the duration of the cycle but might
not be locked. Opening the lid will result in the cycle canceling. Any faults
that may occur during these activations may or may not appear on the
display but will be recorded in the 'Fault History' section.
