Horus Posted May 31, 2010 Report Share Posted May 31, 2010 A Sundance Altamar spa had been sitting with water for a couple of years after being used regularly. We cleaned it out completely and and filled it up for a second run at life. All worked beautifully, but we notice that the temperature on the pan is about 10 degrees warmer than the temperature of the water. Now it states the water is 104 degrees, when the water is actually only 94. No way to get it up that last ten. All other functions work fine. Does this seem like a thermostat problem or one involving the heater? The temperature was always ten degrees below the temperature stated on the panel from 80 degrees on up to 104. Our spa is no longer under warranty. Thanks for your help. HP Quote Link to comment Share on other sites More sharing options...

JerimiahR Posted June 1, 2010 Report Share Posted June 1, 2010 If it heats at all, the heater is fine. Those either work or don't work. If the temperature is not regulated properly, it has to be a thermostat issue, as that is what regulates when the heater turns on and off.

THE SPA GUY Posted June 1, 2010 Report Share Posted June 1, 2010 I would check the temp sensor,, a faulty temp sensor can cause this, Quote Link to comment Share on other sites More sharing options...
