Water leaking inside from the AC

[HDRider]

Our Oliver is a 2023 with the Truma AC.

 

If you live in the south you know how hot and humid it is right now.

 

I turned the Truma on about noon today.   I went out just now to turn the AC off and water was leaking like crazy inside luckily falling squarely in the aisle and not on the twin beds.

 

Does anyone know why this is happening?  It has never happened before.  I routinely run the AC when we are home and the Ollie is docked.

 

Thanks

Drop the nose a little.  Is it dead level now?

Based on my recent Truma dissection and research, I am suspicious that your condensate lines are at fault. The Truma has a pan under the evaporator to collect condensate.  The pan has a drain and overflow on street and curbside. It is designed so that if the condensate lines become occluded, the condensate will pass through the overflow and onto the outside of the trailer.  If both the condensate drain lines and the overflow are occluded, I understand that the condensate can drain into the trailer.  Furthermore about a foot from the evaporator pan, there is a connection where the condensate line from the pan connects to the condensate line in the trailer. Again, based on my understanding, if this connection fails, water can then drain from the unit into the trailer.  
I hope this is clear and helps.

it isn’t too difficult to investigate these  issues further but it does involve an hour on the roof of the trailer, a T25 and T30 driver and some sealant to reseal the shroud cover screws after  reinstallation.

I don't have the Truma, but on mine, the condensate line at the AC was not hooked up at the factory.
I'd pull off your interior cover and see if yours has come loose, or was overlooked at the factory.
Easy fix if that is all it is.
Good luck.

The nose was down.  I raised the nose and the leaking stopped.

 

I find it concerning that the angle of the trailer, ever so slight, could cause this.

That sure sounds like the problem.

Funny you post that.

 

Last summer my AC was dripping down the front street side corner.  Oliver blamed that on the angle of the trailer.

 

Something is fishy.

I think that @Patriot comments in the above mentioned link are most appropriate. The condensate lines cannot be kinked. It is pretty amazing that the lip in the condensate tray between the drain proper and the overflow is only a few millimeters at best. But having said this, if both condensate lines are draining well no water should drain down the side of the trailer or into the trailer regardless of the leveling of the trailer. I will say that I was afraid to really blast the condensate lines with high pressure from below, to prevent separating the connection in the lines I mentioned previously. I had already sealed up the unit before I applied the compressor to the drains under the trailer.
