Cal Spa topside control panel cycles from 83 to 103

My Cal Spa V-300 topside control panel cycles from 83 to 103 and the low pump speed is always running like it is in the filter cycle. None of the buttons on the control panel work.Should I replace the TS control panel or is it more extensive Thanks

What is the actual temperature of the water in the spa by using a thermometer? It may be something else causing this like a temperature sensor.

actual temp seems high 113 degrees

If your actual water temperature is 113 degrees your spa should be going into an OH mode or over heat protection. Is your spa pump running constantly?

First reading was wrong Temp is closed to 102 degrees the pump runs off and on continuously I can't change any settings on the top side control panel and still get the temp cycling from 81 to 103 degrees. It sounds like its stuck in filtration cycle
Thanks jlach

temp was wrong it is actually 102 degrees pump sounds like it is in filtration cycle mode temp on control panel shows 81 degrees and cycles to 101 and back again can not start or change anything by pressing buttons on control panel I have reset hot tub by cutting power to breaker when power is restored the same thing happens again thanks

At this point it sounds like it may be the circuit board or temperature sensor causing it. If it were me I would start with a new temp. sensor and if the spa still does not operate properly then I would think it is the circuit board.

Mary thanks for your help I took apart the connections to the the control panel heat sensor and circuit board cleaned them re-installed and lo and behold the tub has been working great ever since. I guess the moral is to check your connections and your hot tub won't be out of service for 6 months thanks again
