   I have a Coast Spa Bronze/Silver with a Gecko SSPA Spa Pack. I purchased it new in 2001 or 2002. Recently it stopped heating. Due to its age and the absence of an OHM meter I replaced the heating element.All went successfully and the new heating element is in --- but apparently not working because I still have no heat. When I have the pumps running the water temperature goes up 7 - 10 degrees and stops. I adjusted the pressure switch as shown in Gecko's troubleshooting guide and it appears to be working. All pumps work, there is plenty of water flow and the digital key pad shows the heater is on, and the digital temperature readout records the proper temperature. The temperature is set cosiderably higher than the water temp. What should I try next? Gecko's troubleshooting guide recommended replacing the pressure switch if more than 2 years old -- do you think this might be the way to go -- or ?

   So the heater is coming on but only heating to a certain temperature and then shuts off? If that is the case you may have a bad temperature sensor and needs to be replaced.

   Ok --- Here's the update. I went back into the works again and readjusted the pressure switch and the tub seems to be heating -- reaching -2 to -3 degrees of where I set it. Would this be considered a normal variance? It seems to me with the old heater it was +/- 2. Also; re: the pressure switch; It seems to be working now since I adjusted it. It been in the tub since new. Should I replace it or see how it goes?

   That is good news. Since that pressure switch is 7-8 years old I would recommend replacing. They will fail over time and I am not sure how much adjustment was done in order for it to function correctly.

   Ok -- thanks for your help. I'm going to order the switch & meanwhile monitor the spa and see how it works. Today temperature was lagging the setting by -6 degrees.
