Mot mike Posted September 2, 2021 Report Share Posted September 2, 2021 So I have a 2008 Marquis spa epic hot tub it’s runs fine holds good heat all the time your in it. If u turn the heat down the heater stops heating and all is well. Hour or so later when the heater is due to it in it does so fine and the control panel shows the circ pump running but it isn’t. The temp raises quickly on control panel then goes to ohh. Any ideas thanks Quote Link to comment Share on other sites More sharing options...
