WARNING — Sales May Continue
Product Sold-Out Sensor Error — the sold-out detection sensor for one or more columns is reporting an incorrect status (showing sold out when product is present, or showing product available when the column is empty)
Equipment: Crane BevMax Glass-Front Vending Machine
Step-by-Step Troubleshooting
- Identify the affected column from the service display — the error will indicate which column's sold-out sensor is malfunctioning
- Check the sold-out sensor plunger or optical beam for physical obstruction — product packaging material or debris can block the sensor from detecting product
- Clean the sold-out sensor contact area with a soft cloth — syrup residue from burst cans or condensation buildup can cause false readings
- Verify the product is loaded correctly and making contact with the sensor arm — misloaded product may not trigger the sensor even when the column is full
