And yes I have a cover for the spa. Just seems like no warm water is coming from the drain.

If I get no voltage under load would you say it is the heater relay board?

No. I saw that is another way to check and verify that the heater was drawing a current. Don't you put an amp clamp on the heater leads to see if it drawing current?

My meter is self adjusting or automatically picks the correct setting. Do you think the bad connection could be on the heater leads? Do the reset switches go bad? I wouldn't think I would get a reading if it was improperly depressed.

My friend recently gave me a Sovereign IQ hot tub. He told me the heater was not heating. I get it home and do some test on the heating element before I fill it up. It has the Watkins No-Fault 6000 heater with the reset switch on top of the element. I open the IQ2020 control box and disconnect the white and black heating element leads from the heater relay board. The element read 9.7 ohms. I then went ahead and filled the hot tub up to see maybe if he didn't have the reset switch properly reset. I fill it up and everything works on the hot tub like the jets, lights, ect but still not heat. I touch the heating element with my hand and it doesn't appear to be getting hot. I'm getting a green light for "OK" on the control board all of the time and a red "heat on" light when I turn the jets off. This seems normal because I have the 110V version and it will not heat and operate the jets at the same time. I get nothing on "control unhooked". I then check the heater relay board by pulling the white and black heater element leads from the relay board and check the voltage coming out of the board. I get 121V. I then recheck the heater element with a ohm meter and get 10 ohms. At this point I think my heater is good and my relay board is good so I pull the filters out of the machine restart it and get the same thing. I appear to be getting circulation because I can see the water rising from the drain on the bottom of the hot tub. I could also feel the water coming out with my hand. So I check the thermistors and high limit sensors with a ohm meter. before the hot tub was filled with water and the temperature was approx 50 degrees outside I was getting about 18 ohms or so on each of the sensors. I really didn't have a good thermometer to check the water temperature but the one I had said approximately 55 degrees. It was a turkey thermometer. I got a reading of 10.5 ohms or so on each of the two sensors. Is there anything else I need to check or should I take the heating element out and lay eyes on it to see if it has a burn hole in it? Any help would be greatly appreciated.
