Vending Machine Not Vending

[VAGABOND]

One of our vending machines will not dispense a certain product. When you type in the code for that specific row and column, the screen on the machine says to "Make Another Selection," or something like that. Could this be because the motor is not working? Or is it something to do with the hardware malfunctioning? Anyway, we are new to this business, and we would be glad if someone could give us some answers. Thanks!

Unfortunately without a make and model I cannot give any good suggestions. Also, if you repost this in the Beverage and Food Vending section more people will see this.
