First post ... my 2003 Hot Springs RX has been checked for any blockages, has new filter, etc. and all is clean/ok. Upon plugging it in, the low jet button must be pressed, the relay clicks and it heats normally. It turns off after maybe 20 minutes or so; as long as I manually do the above repeatedly, it will get hot. But left on its own, no heating takes place. Any thoughts?
