Since the playfield swap, Pinbot has been running really well and been a joy to play. Recently though, an error appeared when the machine was switched on. The game detected there were errors with 3 of the switches, and reported them during the start up sequence. They are reported as “switch adjust” errors and the knocker fires off 4 – 5 times for each one. It’s an obnoxious sound, and certainly gets your attention that there is an error. The game reported that there was an error with switches 35, 36 and 37.
