60 is arch rotate failure IIRC. As for which prox switch it is specifically, I couldn't tell you off the top of my head, I'll look at my cheat sheet tomorrow and let you know if nobody has answered you first. Also 39 I know off the top of my head means that the wash has been out of service for at least 15 minutes. 28 I don't know off the top of my head, I'll look on my cheat sheet for that tomorrow too.
