DN3800 BEVMAX 4 VEND ERROR

[NYCandyMaN]

having an issue with a bevmax 4 3800, originally had an issue with the picker, as so i though, here's what happened, first few months the machine would work good, then it started to drop bottles, so i changed the picker hoping it would solve the problem, it didn't, 3 brand new pickers later it is still the same problem, but now it would vend a few drinks and then stall out, it would not pick the drink, come back empty, if i put a drink in the picker, it would vend, and then reset, and then would vend again for a bit, and then the same problem happens again, except this time i would get VEND ERROR, where as before i did not get that, now i was told to swap out the port assembly, hoping it would fix it, did that, still getting VEND ERROR,  i tightened up the belt a bit, like 2 notches, nothing crazy, thought it was loose, i checked for errors and all the time i am getting the same error CTRL PWR OUT, i am assuming that there is nothing more to change in the machine except the board now, or to at least have it checked out, was told by the seller that the boards rarely go bad on these machines, so that never happened, he says that VEND ERROR can only be picker or port assembly, the picker moves freely in all directions (i only say this bc i was told to change the XY motors at this point) which is not something i want to do. now i will be putting back the original picker and see if anything changes, if anyone has any suggestions, would highly appreciate it, my last resort is to have the board checked out, as there could be something wrong with it, so i will buy a used one just in case, and send out the original for checkup.

Have you tried to call National Vendors Tech services?  They can help you by walking through the testing sequence. The "CTRL PWR OUT" error code is telling you the machine has been powered down. This should be normal as you need to power down machine to replace the components you described in you message.  My guess is that you have a bad product sensor.  Let Crane National determine that for you  when youy call.   800-628-8363.  Be prepared to be on phone for a while
