Indicates the machine’s coin inlet sensor has been blocked for more than a minute. This is an optional component not installed on all venders and prevents coin insertion into the system.
Click steps to track your progress.
Inspect the coin inlet mechanism and sensor area for any visible foreign objects, debris, or physical obstructions.
Verify that any associated mechanical parts, such as coin rejection levers or gates, move freely and are not jammed.
Check the electrical cabling and connections of the coin inlet sensor to its control module for looseness, damage, or improper seating.
Consult the system's electrical schematics and documentation to identify the sensor type and location, and verify if it's configurable or can be disabled if it's an optional component.
Measure the output signal of the coin inlet sensor (if accessible and non-destructive) to confirm its state when clear versus blocked, comparing against expected values in the documentation.
