I bought a Hague WaterMax 63BAQ used water softener about two years ago. I had a local plumber offer to install it in exchange for some computer work. Once it was installed for a day, it started making a clicking noise and the digital display would say 'Home Not Found'. I unplugged it and let it sit for a few years.
I'm not questioning the diagnosis - just very curious as to what parts it looks like were replaced. Does anyone know what these are?
