    I want to soak in my new-to-me tub! That's what I'm interested in.

  1. Here is the back of the heater board and the main board. I do not see anything burnt. If you see something that looks out of place please let me know.
  2. Filter is out. I can't even get the 240V to the heater leads to really test whether or not the heater 4 Ohm reading is acceptable. It has good flow, circulation, air and jets and waterfall are all strong. So, my problem has to be on one board or the other.
  3. I do not get 240 to H1 and H2. Whatever pathway sends the voltage there is not working.
  4. @CanadianSpaTechI added some pics. I am getting the voltage values from the main board to the heater board. It seems like the heater board is not getting the proper signal to the relay board to send that power out to the heater itself. I also jumped the pressure switch on the main board with no luck. I can see a small "heater on" LED up on the top much like the Jets On LEDs but, it does not light regardless of what I do. It has a circulation pump running when the jets are not on and the jets all work in their various modes. When I had the heater out to repair a leak, it registered 4 Ohms from one side of the element to the other when it was isolated on the bench. So, now I am ready for the next trial areas. Thanks
  5. So I have a 2017 Caldera Paradise Martinique not heating up. It has power, no tripped breaker, and I have isolated it to the board. The fuse on the main board is fine. The LED for the heater does not come on. So, where do I start with troubleshooting? I am very handy with tools to include my voltmeter and resoldering board components if I have to. I even wish I could get a repair manual but, I am sure they are only available to factory authorized service reps.
