Combo configuration reset

Combo machines combine snack and drink systems, so separate the failure domain before replacing parts. Restore factory settings and reload configs.

• Test snack and drink sections independently.
• Verify shared power rails and controller status.
• Check for door switch and service mode conflicts.

• Isolate the failing side and swap known-good parts.
• Reset controller and re-run configuration.
• Confirm pricing and selection mapping after changes.

• Document configuration backups after updates.
• Train route staff on both snack and drink checks.
• Inspect harness routing during each service.

• Issues persist after a controlled test and documented settings.
• Errors repeat across multiple machines or locations.
• You need replacement parts or manufacturer diagnostics.
