I just started having an issue with my F2K. The solenoid in the ball trough will no longer serve the ball into the shooter lane. When called for, the solenoid fires over and over but it is as if there is no longer enough power to force the ball up and over the edge of the trough to get it to roll to the shooter lane. Eventually, the ball will rest on top of the second ball and the solenoid will stop firing. I have included a photo to show what things look like once the solenoid stops firing. Once in awhile, the ball will make it up and over the edge and enter the shooter lane, but not very often.
Thoughts on how to get this resolved?
