Jfrench Posted January 13, 2022 Share Posted January 13, 2022 Good morning community I have a USI 3172 Drink 3120 Snack "Combo Set" and the beverage side reads "Fail" anytime you attempt to test or purchase products. Any advice on correcting and troubleshooting this issue? Link to comment Share on other sites More sharing options...
Vendo Mike Posted January 20, 2022 Share Posted January 20, 2022 I'd be looking for an open in the motor circuit. Possible fuse or disconnected harness? Link to comment Share on other sites More sharing options...
AZVendor Posted January 20, 2022 Share Posted January 20, 2022 If it recognizes the selections if you try repricing them then the board is good. Then you probably have a bad umbilical harness between the machines maybe caused by someone bouncing the machine. Link to comment Share on other sites More sharing options...
AngryChris Posted January 21, 2022 Share Posted January 21, 2022 I always suspect the umbilica cord in this case. Always. Link to comment Share on other sites More sharing options...
