Possible Causes
Loose harness between coin drop/card reader and control, Failed coin drop assembly, Faulty card reader interface, Control board payment input failure
How to Fix / Troubleshooting
Safety first: Disconnect power before servicing coin or card reader wiring.
- Check payment device connections: Access the coin drop or card reader area and verify all connectors are firmly seated and free of corrosion.
- Inspect harness: Follow the harness from the payment device to the main control. Look for pinched or cut wires and repair as needed.
- Test coin drop: On coin models, manually operate the coin slide and verify the microswitch actuates. Replace the coin drop assembly if the switch fails or the mechanism is jammed.
- Card reader diagnostics: For card systems, follow the reader manufacturer's diagnostic procedure. Replace the reader or interface module if it fails tests.
- Control input: If the payment device is good, the control board's payment input circuit may be defective and require replacement.
