Ok, if it heats up and then gives you the flow error after resetting the breaker then that means the pressure switch is stuck closed. Normally the switches are preset when you buy them. No one changed the adjustment on the new pressure switch sis they? What we need to do is turn off the power, disconnect both wires from the switch, then put a meter on ohms or continuity and see if the switch still has continuity even when the pump isn't running and let me know. Thanks, jeff
Alright, if it isn't closing either, even when the pump is on, and you're sure your flow is good, then he's going to need to adjust the switch on the spa so that it's opening with no pump running, and closing when the pump is running. If the circuit board doesn't detect both an opening and closing of the switch, it will never stop giving you the error message. He'll have to attach a meter to the switch and calibrate it while the spa is running.
Can you post me a picture of some of the equipment area, including one of the circuit board and the surrounding equipment. The main issue we have here is that the pressure switch isn't even closing. So for that to happen, either he isn't testing it correctly, or you've got a valve stuck shut somewhere, something somewhere is restricting the water flow. I could figure it out quickly if I was sitting in front of it, but I'll need to see what we've got going on with some pictures hopefully. Pressure switches can be adjusted down to close circuit with virtually no water flow if you lower the setting down low enough. If he's tried that and the switch still wont' close, then I need to see what we've got going on. Thanks, Jeff
The question was still showing as open on my end as I hadn't heard back from you since the last post I sent. If you still need help, I'm happy to do so, if you've got it resolved, please rate me on your end to close out the question. Thanks so much, Jeff
