I have a 2 year old Gatsby 65 model and the display shows PS2. If I turn the pumps on, the circulator will restatrt, and the code will be gone for a few days. The temp readout is at 104, but the thermometer in the spa reads 81 degrees. Any suggestions??? Help?? This is the second issue in 2 years.....last year I had to replace the circulator motor...after 13 months.

Look to see if that circulation pump is working... if you had a similar problem before, it may have happend again. Also, you might want to check your pressure/flow switch. It may be weak or out of adjustment. Try removing the filter next time you get the error message and see if the pump and heater kick on again. If so, your switch is the likely culprit.

Charger....My circulator pump is working. The heater works when the circulator pump runs, but doesn't come up to temp. The readout says 104, but the floaty thermometer says 82-84. Sometimes the circulator will shut off and displays PS2. If I start the other 2 main pumps, the circulator and heater will start again, but still not come to temp. Everything is working at present, just not coming up to temp. Possible heater problems?? Why would the digital readout temp be at 104 and actual temp be that low?? Bad thermostat or flow sensor??
