Ok, I lived with the spa doing this stupid constant restarting. While really annoying and is probably really hard on the pump, it started something new that I can not live with. I notice this morning that the spa was up to 108 degrees, totally unacceptable. So, any ideas on how to fix this?
I have an older Laguna Bay Spa and it's doing something that is driving me up the wall. It starts a heating sequence and runs for a few minutes, the stops. Almost immediately it restarts the heating again. It does this sometimes for 45 minutes or so. Sometimes it will restart after a couple minutes, sometimes almost with only a second or two. I figure somehow either the sensor for the temperature control has gone wacko or where ever the sensor is it isn't reporting correctly. Any ideas?
