Mike4 Posted December 21, 2021 Share Posted December 21, 2021 (edited) I have a Dixie Narco 501E that I think the Main Board is shot. Started with me not being able to get into SP mode by pressing 1&2, also people are telling me its taking money and not vending. Yesterday I went there and it thinks the number 2 button is being depressed and dumping diet coke selection every time a dollar is dropped. I pulled the membrane to make sure it was clean but still giving me issues. Some of the codes its throwing are.... SS-9 SS-2 SS-7 also... I get this scrolling .... HD 5402194.26 I may start with just the membrane and the cable to the membrane since its cracked at the plug. But does this all point to a Main Board issue as well? If I search up a Main Board for replacement, are there any variances I should be aware of, or just any 501E SIID board will work? I see them on Ebay for as little as 40 bucks but not sure if I can trust them. I want to attempt to fix this before I go the next route and buy a new machine. Currently sitting out of service.

lacanteen Posted December 21, 2021 Share Posted December 21, 2021 The membrane alone can cause all of these problems. 1 Link to comment Share on other sites More sharing options...
AZVendor Posted December 21, 2021 Share Posted December 21, 2021 Yes, replace the selection switch membrane. 1 Link to comment Share on other sites More sharing options...
cvending Posted December 21, 2021 Share Posted December 21, 2021 If you think ot is a board issue, pull the battery from the board and let set for 10 minutes. Replace the battery and power up. This means you will need to reprogram the machine. I agreed to try the selection membrane first. 1 Link to comment Share on other sites More sharing options...
Mike4 Posted December 21, 2021 Author Share Posted December 21, 2021 (edited) I will try the membrane first. In the event that I do pull the battery, what all needs to be programmed besides prices? Complicated process? Edited December 21, 2021 by Mike4 Misspelled word Link to comment Share on other sites More sharing options...
AZVendor Posted December 22, 2021 Share Posted December 22, 2021 It is just a membrane issue. The HD is historical data and will show historical cash sales. That is supposed to roll over at 9999.95 or maybe 99999.95 so I don't know why you have such a high number for HD. Link to comment Share on other sites More sharing options...
Mike4 Posted December 22, 2021 Author Share Posted December 22, 2021 Thanks for all the tips. I will update after replacing the membrane with results. Mike Link to comment Share on other sites More sharing options...
