If turning on the porch light continues to blow fuses, then the problem is most likely in that part of the circuit.

Thanks. We don’t have a pump switch in the shower bay (At least I haven’t located one)

Now the mystery is locating the curcuit for the porch light.

If I am not mistaken, the door handle is on the same circuit as the porch light. The easiest thing to pull might be the handle. Process of elimination...or take it to a dealer.

I have the 24fw model so maybe the shower bay stuff is different than your RW. Heres what my panel looks like. The pump switch is just left of where the shower hose comes out.

Same as my 2019 dynamax isata 3 24fw. I would go out and press the water pump switch in the outside shower bay, to allow the inside water pump switch to be on in the up position and off in the down position.. I had to do this after turning the pump on from the outside shower bay.

Thanks Brian. We’ll check that out. Unfortunately our warranty ran out Monday 3/25. We seem to have more problems after we pick it up from the dealer for minor warranty work. We’re trying to find a different repair shop, but there’s not many reputable ones in our area ☹️

Well that makes sense! We must’ve switched that when we were trying to find out if the outside shower worked. Thanks much!

Thanks! Learned something new!!

Any time a switch changes form up to down to be on it means it's a 3/way circuit. (don't ask) There are 2 switches involved in your pump system. It appears there is 2 switches on the WH also. there still will be a fuse at the water pump.

Look for a mobile RV repair tech that has good reviews. We have a number of them around So Texas and I would think Scottsdale would be flush based on the winter RV crowd. I think the mobile techs are better trouble shooting these type of issues.

Oops! Thanks for the correction. Don’t know why I made that big boo boo other than temporary increased stupidity. [emoji52]

Hmm... that could be it. We’ve had a lot of rain in Scottsdale lately. We have a mobile RV technician coming over in a week. I’ll see what he says.

Sounds like the OP has identified a short in the porch light as the source blowing the fuse which also runs the water pump.

Does anyone know the manufacturer and part number for the outside LED porch light that Dynamax uses? I would assume it’s in several different models and not just the Isata 3. Maybe available on Amazon?

The porch light looks like it’s sealed. Not sure how to open it up.

I'd start with the 'low hanging fruit' first. The lighted door handle also comes on with that switch and it is easily removed with a few screws.

We actually started to unscrew the door handle, but my husband didn’t want to mess anything up. I’m wondering if this is also related to the step problem we had, where it wasn’t retracting. I think this is all the result of the shoddy work we had done by our local dealer who worked on our step and slides. They actually made our slides worse before they fixed them and gave us bad advice about our batteries, because they let them run down while our RV was in their shop. You probably don’t want to hear all of this, but its been a frustrating experience. And our warranty ran out on March 25.

We’ll try the handle again and see what we find, but not sure we want to work with wires. Found a reputable mobile RV technician who is coming on April 15, one month before we leave on a long summer trip.

Thanks all for your advice and for not making me feel like an idiot!

You could test to see if the step is on that same circuit by removing the fuse for the pump and checking to see if the step still works. If the step is on that same circuit anything is possible. Could be as simple as a pinched or scuffed wire grounding out on bare metal somewhere, of course finding where that is is the challenge.
