Snack drop sensor troubleshooting

Snack vending models share similar drive motors, selection switches, and payment interfaces. Use a consistent diagnostic path to isolate root causes. Handle false drops and no-drop faults.

• Confirm vend motors cycle and home properly.
• Inspect selection switches for alignment and continuity.
• Verify pricing and product configuration for each column.

• Clear jams and test with a known-good product.
• Calibrate selection switches and verify motor timing.
• Update firmware if the controller supports it.

• Clean spirals and trays during each service.
• Log recurring mis-vends by column.
• Replace worn couplers on high-use selections.

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