zsqure Posted October 2, 2012 Report Share Posted October 2, 2012 Ok, I am at the end of my rope. I have a sovereign model hot spring spa. It has the original no fault 6000 heater, the heater board was replaced a couple years ago. It looks like the newest board, and has black colored relays. My spa was working fine until I changed the water. The leds on the main board indicate the heat circuit is on. the heater has a resistance of 9.8 ohms. It has power going to it, the power outputs on the heat board have 120v when I check white to ground and 120v when I check black to ground. If I check black to white there is no voltage. I removed the cover over the reset switch and checked power there, 120v on each side of the switch (black wire to ground). The circulation pump is circulating, i can see ripples on the surface. I have removed the filters in order to reduce resistance in water flow. i dont know why it is not heating. Quote Link to comment Share on other sites More sharing options...

If the "heater on" light is on but there is no voltage to the relay where the black and white wires connect then the relay board is bad. Does your heater connect to the board with push on " flag" terminals or do they push up into slots exactly like the incoming power wires attach? The new style board requires the old flag terminals on your heater to be cut off and stripped back, then they slide into openings just like the main power wires do.

zsqure Posted October 2, 2012 Author Report Share Posted October 2, 2012 "If the "heater on" light is on but there is no voltage to the relay where the black and white wires connect then the relay board is bad" That sounds like a solution, but I do have power at the output of the heater board if I check it black to ground or white to ground. If i check it black to white there is no power. AM i HAVING A MENTAL BLOCK CONCERNING THIS? Quote Link to comment Share on other sites More sharing options...
zsqure Posted October 2, 2012 Author Report Share Posted October 2, 2012 Can I hook the heater to a plug, plug it into the wall and see if the heater will work that way? Quote Link to comment Share on other sites More sharing options...
Dan.The.Spa.Man Posted October 2, 2012 Report Share Posted October 2, 2012 Black to ground and white to ground means nothing. You need the proper voltage between the black and white. Either 120 or 240 depending on the voltage of your tub. Quote Link to comment Share on other sites More sharing options...
zsqure Posted October 2, 2012 Author Report Share Posted October 2, 2012 Awesome, that answers my question, heat board it is then. Thank You! Quote Link to comment Share on other sites More sharing options...
