Mobile here, so I can't copy/paste the link: go to the owners thread and do some digging. There is a lot of information there, and I am sure there are some pointers on these problems, especially the mist problem.

BigD is on the right track, go into switch test mode and test any switches that are in the error messages. For mist, remove the ball, and swipe you hand across the middle of the PF from bottom to up. You should hear the opto switch give an audible beep. If not, that opto is not registering.

LOTS of help in the owners thread. A lot to read too, but it is becoming the Bible of BSD knowledge.

Sounds like your long range opto is off just a super-tiny bit. I would go to the left side of the machine, as it i far more accessible, and see if there is any play in the receiver (black unit on the left side).

Awesome! Was that on the mist ball side of the game, or the left side where the mist ball normally does NOT sit? Just for posterity's sake. I always forget which is the transmitter and which is the receiver. I'm pretty sure transmitter is on the right and receiver is on the left....
