Bill Shepherd Posted August 26, 2018 Report Share Posted August 26, 2018 I have a 2007 Hot Spring Prodigy with temp error lights flashing. I replaced the high limit and thermistor, but no help. I jumped the built in pressure switch and everything works fine. Since the replacement heater does not have a pressure switch, is it ok to run the spa with the switch jumped?

Cusser Posted August 27, 2018 Report Share Posted August 27, 2018 I wouldn't run without a pressure switch unless I was there in front of it. You or a plumber could install a universal pressure switch. Quote Link to comment Share on other sites More sharing options...
Hot Spring Official Posted August 27, 2018 Report Share Posted August 27, 2018 You should get the heater changed, and make sure the replacement has a pressure switch. Quote Link to comment Share on other sites More sharing options...
