Ive created an account so I can hopefully figure out this issue. I just bought a Bellco Bingo pachislo machine at a yard sale and cannot for the life of me figure out how to get rid of this "CR" error code. When I turn on the machine it plays what I can assume is the post bonus/error maintenance music and displays a "CR" error code on the door. Ive tried resetting "reset key, change odds, pull spin knob" and have had no luck so far. I also pulled the coin reader out and cleaned it with alcohol and q-tips all along the inside, tried removing the makeshift quarter conversion made with a flash card as well, all with no luck. I made sure the hopper was properly connected as well. I think its also worth noting that the magnet solenoid on the coin reader that redirects the coins from the tray to hopper is not being activated at all, so all the coins i put in are just going into the tray. The only thing that I could possibly think of is that maybe my resets arent working because the sensor on the spin/pull knob are dirty, therefore its not completing the reset process. If anybody could help me out with this issue it would be very appreciated.
