10.20 Restore Factory Settings Menu
The RESTORE FACTORY SETTINGS menu (
Figure 10.27
) allows a service technician to restore the dispenser settings
to factory default. This can be useful when too many settings have been changed and the dispenser is not operating at
optimal conditions. When restoring factory settings, certain settings can be retained such as the defrost schedule, auto
defrost blackout times, language and units (English or SI). Select which settings are to be retained before restoring the
factory settings.
10.21 Diagnostics Menu
The
DIAGNOSTICS MENU (
Figure 10.28
) is a powerful feature of the 37x dispensers. Any time a malfunction is suspected,
the best option for the service technician is to first run the diagnostic sequence for the system involved. This can eliminate
hours of guesswork and parts swapping.
There are two diagnostic sequences:
1.
Beater Circuit: This sequence will help identify any component failure in the beater circuit system such as the beater
motor and capacitors.
2.
Fill Circuit: This sequence will help identify any component failure in the fill circuit system such as solution or CO
2
solenoids or any leaks in the product delivery system.
To begin, determine what the possible issue with the dispenser may be. Select the appropriate diagnostic sequence.
Initiate the sequence and let it perform its checks. You may be asked to perform some manual operations or answer
questions to proceed with the process. If any errors are found, the display will note the error and provide an error code.
Refer to the “Diagnostic Fault Codes” section (Section 11.3) of this manual to diagnose the cause of the error.
