Can they just "go bad"?
I bought a used 2012 Jr and the other day it just hung. My return is on outlet 1 always on...and noticed 0 flow. All lights on modules were flashing (VDM LSM FMM ETC)
Also occasionally (3 times today) I get email that would indicate a restart (set off message). And it looks like the probes drop out because temp orp ph etc all fly off the otherwise stable chart (all probes same time)
firmware is is up to date and I factory reset and re setup everything.
