Your cargo bay thermostat may be calling for heat and energizing the circlation  pump relay.

Our Aquahot, an AHE-100-02S, has (I think) four pumps - three pumps for circulating heating fluid and a diesel pump.  Which model Aquahot do you have and which pump is your question about?  If you have the engine pre-heat function, then the pre-heat switch may be ON.

I was trying to say everything all switches are turned off but the pump continues to run.

Identify which pump is running and then work backwards on the wiring from there. If you come to a relay or switch pull off the wire at that point.  Then you can figure out what is causing the malfunction.

Happy to report, problem solved! I followed the sound and realized after crawling under there and following the sound the switch was accidently turned on by the cord real (as it rewound). It was pushing on the switch. Thanks for you ideas and help!

The best and usually easiest fixes are the "oops!" ones. 😅
