Single Column Fails to Vend
This section details troubleshooting when the machine powers on, but only one specific product selection fails to dispense while others operate normally.
- Same column jams repeatedly after clearing: Investigate column dimensions, product size compatibility, and mechanism wear before returning to service.
- If the mechanism does not move freely after clearing product, a qualified technician must inspect for bent linkages or internal binding.
- If the issue persists after clearing, a qualified technician should assess the column's mechanical integrity.

Location Help
Where to find this
Use this as orientation before touching the machine. It is location help, not a repair instruction.
Start at the affected product shelf or selection row; compare the tray, coil, and product path with a nearby working selection.
- Mechanical assembly that physically selects and dispenses a product from the correct column when the customer activates a selection.
- Vend mechanism assemblies per column
- Column selection linkages
- Product support trays or shelves
