Quoted from Sticky:
This is driving me nuts. As I've gotten better at playing the pin I can get three balls into donut heaven to start multi-ball consistently each game. The problem is the third ball never gets released staying on the second hook/sensor. So the machine keeps going and I have to remove the glass and manually push it out as it just stays there for some reason. This picture should help illustrate what I mean:
It only happens in the multi-ball and any other time there are balls locked the game releases them after the final ball drains without issue. What could be causing this only during multi-ball?
It's no longer fun to play when every time I get the donut heaven multi-ball I have to remove the glass to push the ball out otherwise the machine just sits there going through the solenoids trying to dislodge a ball.
How do I fix this?
The weight of the three balls is what lets the first 2 balls get released so when it comes time to release the 3rd one there's not enough weight to push it past the switch. What's the pitch of the game? All this is just a guess.
