Machine Completely Dead Diagnostic

This diagnostic flow is for when the entire vending machine shows no signs of power or operation, requiring checks starting from the facility's electrical source inward.

Qualified technician handoff: stop before live electrical testing, sealed-system refrigeration work, compressor service, or protected-compartment access unless a qualified technician is handling the work.

  • Burning smell or visible scorching at any point: Immediate de-energize. Tag machine out of service. Escalate to licensed electrician.
  • Water intrusion near electrical components: De-energize. Do not apply power until fully dried and inspected. Escalate.
  • If the issue persists after initial checks, a qualified technician must assess the main electrical supply and internal power distribution components.
  • If the issue involves the main power input, a qualified technician must be called to safely test the facility's electrical connection and the machine's main breaker/fuse.
