serge Posted October 30, 2015 Share Posted October 30, 2015 Hello guys! I'm new here and I hope I'm posting in the right section.I've purchased two used Vendo 511 soda machines and one is not operating right. I've never had any vendos in my opinion Dixie narcos are much better machines.Here is what it's doing to me. When I open my door to restock the soda bill validator would start making noises and while I restocking the machine bill validator keeps making noise and by the time i'm finish with restocking - display,bill acceptor and coin mech would turn off, but everything else is still on including the light bulbs .The only way to turn it back on is to pull out the fuse and put it back in. Immediately my thought was it’s a fuse so I replaced it with a new one but it still doing the same thing.What’s weird about it that it can go off when I test my motors or keep the door open for a while.. and I can care less if it does it when it's me triggering something as long as it's working after I close the door.Today I came to check on it and I see that my display is off without me doing anything to it. it was just off, like it was no power..I opened the door and I see that compressor is running ,light bulbs are ON but display is off and bill acceptor is off as well after I played with the fuse it turned back on .So my problem is display,bill validator and coin mech would turn off on it's own and don't know when and why. It’s killing me thinking that my machine might go off at any time and people can’t buy anything.i have two identical machines and one is perfectly fine ,never done that to me, but this piece of junk is driving me crazy .I called vendo tech support but they couldn’t really help me much they suggestion was to switch out the mother boards between them two and see if it still does it.. but it’s not easy to do because they are very far apart .I just hope maybe someone here had the same issue and know where the problem is.

lacanteen Posted October 30, 2015 Share Posted October 30, 2015 I recently had one doing the same thing. It was the card reader loading the transformer down. I pulled the card reader because the machine is scheduled to be changed soon. My guess in your case is a weak transformer or your changer or bill acceptor are loading down. try a spare bill acceptor first, then changer. It will not be the computer board because we tried that first. Link to comment Share on other sites More sharing options...

AZVendor Posted November 1, 2015 Share Posted November 1, 2015 Make sure that your door switch works properly and is being pressed in when the inner door closes against it. Link to comment Share on other sites More sharing options...
