Product Does Not Vend — Diagnostic Flow
This guide assists in diagnosing why the entire machine appears dead, showing no signs of power or activity when switched on.
- Motor smoking, excessively hot, or making grinding noise: Disconnect power. Do not operate motor. Replace motor before further testing.
- Burning smell, arcing, or visible electrical damage: Disconnect immediately. Escalate to qualified technician.
- If you suspect an issue with the main power input or internal wiring, contact a qualified technician immediately.
- If voltage verification is required, only a qualified technician should proceed with testing the low-voltage supply output.
