AMS Sensit Combo Vending Machine Error Err5

CRITICAL — Machine Locked

Health safety timer expired — machine locked because internal temperature exceeded FDA food safety limits

Equipment: AMS Sensit Combo Vending Machine

Step-by-Step Troubleshooting

  1. The machine has automatically locked sales to prevent selling temperature-abused perishable products
  2. Check if the door was left open — Err5 often triggers after a restock where the door was open too long
  3. Allow the machine to cool down to safe temperature — the health lock will clear automatically when temp drops below 41°F
  4. If the machine is not cooling, troubleshoot the refrigeration system (see Err3 above)
