I am getting 120V at the connection for the heater for a 240V rated heater. I have checked the fuses. I am also getting a FLO code. I have a in.xe spa pack. Should the spa pack be replaced. I am reading about 40 ohms on the 4kw heater.

    Doug a FLO error msg is usually related to the filter, Flow switch and or circ pump. Check that your filter is not soiled and that the wiring is patent to the Flow switch. Check that you have good flow coming through your circulation jet. Do you have a question about your heater? You reference your heater but you don’t say if it’s heating or you have a fault with that. If you would like a link to prices and availability on spa filters send me the part number stamped into the top of your filter.
