We just bought a house that has a South Seas Spas 4 seater hot tub (don’t know the model). Today, we decided to start prepping for draining and refilling so that we can start using it when the evenings get cooler. Prior to this process, the jets would cycle periodically as expected. Now that we’ve turned the jets on, “Jets 2” turns off as it should, but. “Jets 1” won’t turn off. Any ideas on what could be causing this? I’ve looked at the owners manual I found online and everything talks about the jets not turning on, but nothing about failure to turn off.
