Quoted from arcyallen:It's funny you say that, as my Wonkavator keeps releasing the ball once or twice immediately after locking it. When did that start? The moment the last screw appeared. I finally connected the dots last night but haven't had a chance to look back there yet.
I bet your diverter flag cam loose and fell off. When it does, it will lie flat in the upper orbit and your ball can roll over it.
Simple to fix. You can remove the coil/post from under the playfield. Screw the flag back on, and then re-insert it.
I had the same exact issue as you describe (balls going into Wonkavator and getting instantly released) and also found two loose screws. this was the prob! Balls that weren’t traveling fast enough would naturally fall into the Wonkavator… the machine would kick them up and instantly recognize it as an error and release them.
I put some blue loctite on the screws before reassembly. Haven’t had an issue since
