Hi,
I have a 2004 Jacuzzi J375 that I just replaced the circulation pump on and am now getting an OH error code. I did drain the tub for cleaning along with the pump replacement.
What I notice is that the circulation pump runs for a while, stops, then I believe the heater starts to ramp up. It sounds like pressurized water/air starting to form and then I see air appear in the flow switch junction. It sounds like a kettle boiling. This is when I get the OH error and at this point I continue to hear the circulation pump run.
It feels as though I may have multiple issues. 1 being the pump not shutting off when it should and 2nd that I have air in the system from the draining. Or, it could just be that air is being introduced into the system causing the OH to happen and the cycle to repeat.
I have spent hours burping the air out, maybe 20-30 times, and while I can get the air that is gathering at the flow switch out to the point of a solid stream, more appears after the cycle restarts as described above.
I have replace the clamps with band clamps and I believe there are no leaks at the joints I have opened
any suggestions on what to try next?
thanks
