I have a 2005 dimension one hot tub and the heater pump has not been working. My friend came over to try to figure things out and he said it was the flow switch or flow sensor or something like that. I don't know what a flow switch is so if someone knows about this could you explain to me what it does- from the beginning? Thank you!
I don't know, as the circuit diagram doesn't explain the logic. Page 30 (below) shows a flow switch, and I can only guess that the circuit might require there to be water flow from the heater pump across the heating element. If there was no flow, the high power heater element might very well burn up. Thus the flow switch to insure water will be there, flowing around the heater element and keeping the heater element from burning up.
