I'd start by removing the front cover and try to locate the drip. Once you've located the leak then that will dictate your next course of action

The old ones had an issue with the drain Plug being Plastic - replaced with Brass and white plumbers tape - sealed.

Open it up find and Fix, usually easy to see and fix.

Let us know,

I just fixed a leak on mine. It was the connection to the hot water line coming out of the Aqua Hot.

Check ALL the hose connections. I had a leak and it was a hose connection.

2011 Ellipse here, but same 450 Aquahot. had a leak with water dripping out the screened vent in the bottom. Turned out to be one of the connections for cold water in, hot water out. This side is hard to get to. There is a small access opening in the rear wall driver side of the storage compartment. I ended up removing the bracket that holds the folding ladder and the panel that was bolted to to get better access to tighten the connections. They had become less than finger tight Opening this up pretty much gave me access to the entire back side of the Aquahot unit. Still a PITA tho.

So start by taking off the front cover to check the zone pumps and inside connections and also looking into that access hole in the rear wall of the storage compartment and see where it's wet and go from there. Water from a leak can travel a long way from the leak source and leaking water from the backside (plumbing) can get to and out the screened opening in the bottom!

What is the leak material? Water? Radiator coolant? HydroHot coolant? That would give a good idea where to start. I have had to replace my original unit, and suggest you work with the factory and a certified repair person/facility. This is a great, but complex unit, normally installed into the least accessible space by the coach builder.
