Troubleshooting protocol
Start safe. Isolate the system. Document the fix.
A consistent first-response sequence helps operators solve common problems without creating a second one.
Record the exact symptom
Note display messages, error codes, sounds, temperature, and whether the issue affects one selection or the whole machine.
Isolate one system
Test payment, vending, refrigeration, or communication independently and record what changes.
Stop before unsafe work
Refrigeration, mains voltage, and heavy moving work should be handled by qualified technicians.
