Any thoughts, ideas, suggestions...
The water pump is DC powered. In my unit, the water pump is under the dining table seat...find it on your unit. If running, turn it off in the control panel.
The disconnect of the AC shore power is not related to the DC water pump.
I suspect something else is making the noise.
