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 ?
