Sanitizing

Hi folks I’m newish here and could use your thoughts. I’m de-winterizing and getting no response from the pump at the Nautilus. It’s a  2023 320s with the P3 Nautilus. I’m trying this off battery power. They appear to have juice and fan, fridge and radio work so power seems there. Does this need to be done on A/C? Inside pump switch had no response either. What am I missing? Thanks.

    It should be fine doing it on 12 volt only, assuming your battery is not depleted. Obviously plugging it in would eliminate one variable, but the pump still runs from 12 volt power from the converter.  When you flip the exterior switch for the pump does the red light come on next to the switch? Have you checked the fuses? Are you saying it is not working because you don't hear it, or because it's not drawing water in? (I'm assuming you are doing a bucket fill and have the Nautilus set to sanitize position.) I have had issues with the check valve located at the intake for the Nautilus. Spring loaded pin can get sticky. The pump may not be strong enough to overcome that valve when drawing from a bucket. If you think there's a chance the pump might actually be working try this: turn the pump off and open the taps to depressurize the plumbing system, gently exercise that check valve with your finger and/or remove the intake filter screen from that threaded Nautilus input and install it backwards, inverted so that the cone of it opens the check valve. Then run the pump and lift your bucket up to the level of the Nautilus. (All this assumes your pump is working, which I understand according to your original post it may not be.)

    Thanks. I am doing the bucket fill and am configured in the sanitize position on the Nautilus. Red light comes on and inside panel reads charged batteries. Thought about fuses but was running out of time so didn’t check, breakers were on. I would assume if it were a pressure issue or even the check valve I would at least hear the pump give it a crank but nothing. Not drawing water. I will look at the fuses tomorrow. Thanks.
