Would a faulty micro switch cause an OU code on a fleck 9100sxt twin tank softner? I’m waiting on some micro switches but in the mean time would like trouble shoot in case it’s my circuit board. I can’t get it out of OU screen after unplugging. Checked out micro switches and the one closests to the timer/motor was open and won’t close.

Can I jump the wires orange purple and black when the gears turn and switches aren’t depressed to see if this is the case?
Hey, wait a minute.

This is awkward, but...
