We have a Dixie Narco 720P 10 rows set up for cans. When coins are deposited and selection is made it vends the entire row and then returns the coins. I replaced the vend sensor first, and then sent in the control panel to DIEB. But it is still doing the same. I noted when I installed the vend sensor that the wires were different color than the machine wire harness - but assumed it was a substitute part, it was D65107100 from D/S vending. I did a continuity check on the wires to make sure there was not a break from opening the door. All 10 rows do the same thing - deposit coins - press button - get four cans - and your change. This is our in-house machine used to pay for agency picnic, Christmas, sort of thing. Since it is not on a vending route I cannot get support. One guy came out - giggled wires, turned it on and off, (kicked the tires) and said I don't know. I already did all that! Can you please help - we have no budget for a replacement. Thank you.
