Crichardson Posted May 10, 2022 Share Posted May 10, 2022 I have a Dixie Narco 501E. Every time things sell out the machines will act funny. The display goes from only having the decimal to having the first selections price 1.25. Whenever I put money in and hit a selection a random selection vends. Also whenever trying to put it in service mode SS-1 pops up and whenever I hit the first selection button it goes straight to HD and shows the number on the display. I used to be able to unplug it a few times and it would eventually go back to normal. Any ideas on what could be going on? Thanks in advance.

lacanteen Posted May 10, 2022 Share Posted May 10, 2022 The selection switch membrane is bad or dirty. Clean the membrane, the rubber strips between the membrane and the buttons, and clean the buttons, especially the bottom. . The membrane is only a $20 part from D&S Vending Link to comment Share on other sites More sharing options...

AZVendor Posted May 11, 2022 Share Posted May 11, 2022 Random selections vending is a bad switch membrane. Its not really random, it moves the selections down one number usually. 1 Link to comment Share on other sites More sharing options...
