When I press the start button for a new game, the machine immediately cycles through firing all the flippers and solenoids (as if it were trying to shake balls loose). All six balls are loaded and in the through or around the outhole. The machine does not try loading balls into the gumball machine.

In test mode, I can successfully cycle through the gumball test - all the switches and solenoids work fine and in sequence for loading and dispensing balls from the gumball machine. I have tested all the individual switches as well a few times. For sure all the through and outhole switches work.

My best guess is that the CPU is not processing the switch information correctly (although it will display switch state in test mode). Could that bee? Any suggestions on how to proceed? Really stumped.

Try removing two balls, then pressing start. Does the DMD show "2 balls missing..."?

If it does, try the test with only one ball missing.

Pages 1-20 & 1-21 in the manual show both automatic gumball test mode and manual mode. Do both modes function with no errors?

Mine did that once. Assuming you accounted for all balls and none were stuck anywhere since your machine sounds like its going into ball search. I shut the machine, took all the balls out, manually loaded the gumball machine with 3 balls, turned the machine on then drained the remaining 3 balls. That resolved the problem for me. If that does not work I would suspect a stuck switch in the on position in the gumball machine.

Also make sure the gumball diverter, upkicker, and opto are working as well. The game also may be set to "Gumball Broken". That might be why it doesn't try to load it.

Make sure all the trough switches work, and that they aren't stuck down. Just found a middle trough switch stuck in the closed position to fix this problem...

As the post is over 2 years old I would hope he fixed it by now. Lol
