I just signed up to the forum after searching for help with our hot tub. We have a hand me down LB that has served us well for about ten years. Last season it would not heat up and we feared it was done for. A local service man came over and literally jiggled some wires and it came on and worked all season reliably heating up and jets working etc. This season it comes on but turns off at about 90 degrees and one end of the tub has no jets. I'm told the weak link is the S2 topside control panel. I am going to try the wire jiggling myself this weekend. Should I replace the control panel? I wondered if there might be anything else I could look at? Spa is wired 220 volts.
Thanks for the help in advance!
