Slot machines were not designed for use outside of a casino, so at times they are not particularly 'user friendly'. On occasion, your machine will show a number (error code) in the display that will not go away and the machine will not accept coins or play. The machine is just telling you something isn't right!
If you were in a casino, you would just ask the next employee that walked by, but at home, you must fix it yourself (or pay for someone to come fix it for you!). Many errors are easily cleared, so don't despair!
Below we have listed some of the more common IGT S-Plus errors and the steps to clear them.
12 - Indicates a Low Battery; Replace Lithium Battery on Board
21 - Coin In Tilt; Check for jammed coins in the comparitor, Open/Close Door
3100 - Extra Coin Out; Open/Close Door
3200 - Coin Out Tilt; Open/Close Door
3300 - Hopper Empty; Refill the Hopper & Close Door
41 thru 45 - Reel Tilt; Open/Close Door
61 - Push White button for 2-3 seconds. Close the door.
61 1 - Turn Reset key on side of machine ONCE.

Hi
I went though and did search on the problem I am having with a slot machine. I got a phone call to service an IGT slot. When I got there I found that the battery was bad and replaced it with a new one. I got the standard error code 61 and I then held the button in until 61 1 came up. I then shut the door and hit the key switch to reset it. The dreaded error cod 61 pop up. So I grab my clear chip and placed it in the board and clear the ram out. Put the game chip back in and a few seconds latter 61 pops up. I did the reset and still no good. I then thought maybe the key switch or the door sensor optics was bad. I could not get it into I/O test so I used my meter on the switch and the optic door sensor. and everything checked out okay. I was able to run my meter wire inside the machine and hooked up to the receiver door sensor and closed the door to see if it was out of aligned. The door sensor worked like it was suppose to when the door was close. I am running out of ideas. I have read other post about the 61 error code and I have done everything I read on this machine. I am hoping someone can tell me something that I am missing.
Thanks
