Water

The water pump is lowly growling in the background, and you can clearly see the water is trickling into the toilet bowl.
The water is trickling into the bowl from the rim, and not up from the drain, correct?

What water pump is making noise, the toilet pump or the main boat water pressure pump? Is the toilet raw or fresh water flush?

If you turn off the pressure water pump, does the water stop entering the bowl?

If it does, great, you won't flood your bowl while you are waiting for Miss Peggie to come and guide you through the problem.

In the meantime don't turn the water on, unless you need it.

I think the joker valve is on the drain side, not the inlet, so I don’t think that’s your problem. It sounds to me more like whatever valve is supposed to separate the toilet inlet from the fresh water may not be closing completely. But as dlochner said this sounds like something @Peggie Hall HeadMistress will solve.

There must be a valve or pressure switch that has failed.

The pressure (water tank) water should not be plumbed to the head. Usually.

This is a Jabsco electric toilet (37072-0092) with rocker switches.
37072-0092 isn't a Jabsco toilet model, it's the part number for a replacement pump motor assembly for a Jabsco 37045 Quiet Flush toilet, designed to use pressurized fresh water. It took me a while to find that information... and once I did, I knew what your problem is:

As you'll see in the plumbing instructions in the owners manual Jabsco Quiet Flush FW owners manual there needs to be a vented loop with an electric solenoid valve in the flush water intake line (the line that connects the toilet to the fresh water plumbing ). The flush button (or rocker switch) opens and closes that solenoid valve allow water to flow into the toilet bowl when the boat's water pump is on to pressurize the fresh water. That solenoid valve has failed--kinda like a leaky faucet-- and is allowing water to seep into the bowl when the water pump is on. Replacing it will solve your problem.

That's the good news. The bad news is, Jabsco solenoid valves have a high failure rate and they aren't cheap!

Btw,...you'll want to print and hang onto that owners manual...Xylem reorders their website at least once a year...I find out they have when all of my Jabsco bookmarks no longer work. And it seems to link I posted to the owners manual didn't work when I tried to open it again here. I'll find one that does...this virus lockdown gives me plenty of time to do it. <sigh>......

If you don't know where the joker valve is in ALL marine toilets (in the discharge fitting), you can't know what it does or how to replace it--which should be done at least every two years.

The pressure (water tank) water should not be plumbed to the head. Usually.
It's SEA WATER toilets that should never be connected to the fresh water plumbing...apparently you've never heard of toilets designed to use onboard pressurized fresh water.

Both of y'all really NEED my book! (see link in my signature). The title (my publisher's idea) is a bit misleading...'cuz although it does deal with every source of odor on a boat and how to cure, or better yet PREVENT 'em, it's actually a comprehensive "marine toilets and sanitation systems 101" manual that explains the laws, describes all the types of systems and how they work, and will help you learn how to operate and maintain your system to prevent 99% of problems instead of having to cure 'em. 'Cuz you get to do any preventive maintenance on your terms when it's convenient...the need to cure a problem never happens when it is! And I'm always glad to answer any questions it doesn't.

I found the working link to the 37045 Quiet Flush owners manual on the Jabsco site and this link does work! Jabsco Quiet Flush FW owners manual I think it'll be a bit easier for you to follow than the literature you posted. You might want to read the plumbing instructions in it before you head for WM...and you can find the vented loop and solenoid valve in a lot of places that are a whole bunch cheaper than WM!

Hopefully you didn't buy just the solenoid valve, but also bought the vented loop and enough hose to install it according to the directions that you'll find in the Jabsco owners manual.

When I looked at your photo showing where the solenoid is installed, there didn't appear to be one. And looking at your photo it appears that Jabsco now offers a combination solenoid valve/siphon breaker (a vented loop IS a siphon breaker)...so I guess you don't need a separate loop after all.

It's just a female to male 90. Doesn't look lin a marine fitting but it shouldn't be too hard to find in the plumbing department of a box store or really good old fashioned hardware store (they do still exist! However, I suspect that removing the leaking end of the hose and wrapping it with plenty of teflon tape will seal it. It's what I use to seal the line coming out of the pump in my birdbath.

What kind of fitting is it? The one where the blue line enters. It looks like PEX. If I recall correctly PEX comes in both metric and imperial sizes. It may be a mismatch between an Imperial fitting and a metric hose.

Looks like a Plex push-to-connect quick fitting, like these - John Guest Speedfit push to fit Quick Connect Fittings. Beneteau uses these too. You could try re-seating the hose. To do that you push the ring that’s around the hose up toward the fitting. While holding that ring up you should be able to take the hose out, clean it, and slide it back in.
