Is it possible to by-pass the hot water heater in the aqua hot and add an 8-gallon water heater to the system?
I have found a water leak coming out of the Aqua-Hot when I turn on the water pump.

I thought it might have something to do with the heater running, but on closer inspection I noticed that there was a small puddle of fluid near the back of the unit. Looking around some more i found that coolant had been running down the AH exhaust pipe and making a puddle on the ground.

I'm not seeing a leak around any of the external piping or pumps so I'm assuming that it's coming for inside of the unit itself.

I haven't found much in the manual about a leak and or how to fix it. I am assuming that it's going to be a major operation to fix the problem but I don't know.

Does anyone know or have an idea of what could be leaking on the inside of the aquahot?

Thanks in advance,
Tyler

The fan works just fine when I jump the 12v+ wire to the heat output on the back of the thermostat, so for whatever reason the original thermostat is not sending the needed voltage to the heater fan.

Since the thermostat controls both compressors on the AC and the heat I'm not sure what I can replace it with.

Has anyone replaced the original PSG thermostat with another model that will work with our AC and the heat?

Thanks

I verified that it was the zone which supplied the Bedroom and Baths.

So, the research began. I determined it was a bad circulator pump and have since then learned those failed frequently.

Newell is replacing them with OASIS units now, yet Aqua-Hot sells Buehler pumps. I've got the Buehler kit on order since is nearly half the price.

The badder news is...a couple days ago, I found water under the coach and discovered a pool of water in my wet bay. Sooooo, I'm really hoping the two are related; in other words, I'm hoping the bad pump is leaking.

However, the leak has subsided so I'm wondering if, one, the fluid has dropped below the point of leaking or, two, I have a leak elsewhere and the reason for the noisy pump is CAVITATION and not bearing failure.

Anybody? Chime in...PLEASE!!]]> Then, the noise became a LOT louder and constant.

Newell wants $1000 for core. not sure if thats per unit! anyone know who the manufacturer is? part number search for 82643Q0624A and 625A nothing . also pn 30127

I am finding similar ones from thermal solutions for $100 each. Of course a mod to the outlets is needed but will go to radiator shop to get estimate.
Any clues appreciated. I get the idea Newell does not encourage home repair as several parts I have obtained quotes are at least 3 times what you can find from distributors if you can get the real part numbers.]]> coolant was maintained at Newell for majority of coaches life.

Our AH has been getting louder during operation, so I decided to replace the bearings using a 5 year rebuild kit for the burner that I found on heatmyrv.com.

I've gotten everything apart and the bearings are nice and smooth but the combustion air motor is very "notchy" when I spin it.

My first instinct is to replace the motor, but I wanted to double check with you all first.

The shaft on the motor turns fine, but feels like I'm turning a knob that has a detent for different positions. Idk I'd that makes any sense but I don't think it should feel like that.

Thanks!

Is there another fuse somewhere that I would need to check?

Is it the relays maybe? I see a few of them on the side of the aquahot near the fuses.

The diesel works great and the heat still works overall.

Appreciate any insights.
