Coin Rejection Issue - Diagnostic Flow

This diagnostic path helps determine why coins are being rejected by the payment system, starting with physical inspection of the coin path.

Low RiskOperator8-12 min
Payments6 stepsoperator-intermediate
  • If the coin mechanism rejects coins despite a clean path, internal mechanical calibration or electrical validation of the coin validator requires a qualified technician.
  • If the rejection behavior suggests a payment controller communication failure, a qualified technician must diagnose the payment system wiring.

Checklist
