I have a Tiger river spa. model Kyber(L), serial #L-340285. It was working fine, but was dirty. I drained it, and it sat for a week. I cleaned it good, and refilled it. When I turn the breakers back on the circulation pump, and heater run for @ 30 seconds, and it shuts down, and nothing works. If I hit the reset switch on the control box, it will again run for @ 30 sec. and shut down. If I turn on the jet pump within that 30 seconds, the jet pump will run as long as I have it on. When I turn off the jet pump, the circulation pump will once again run for @30 sec. and shut down, and nothing will work until I rest it. I took apart the control panel
, and cleaned the bug crap, and moisture from it, with no help. I'm thinking there's probably some kind of sensor letting the control box, know it has water in it, that isn't working, thus shutting the pump, and heater down to protect them, but I don't know what I looks like or where it is. this is a used spa, I got several years ago, and I don't have a manual.
