Water near refrigerator at night in Entegra Ethos LI

[RS_SMS]

We recently bought an Entegra Ethos LI. I had water leaking from the water heating box that I was able to repair and don't see any other leaks. At night when the Timberline heater is used I'm getting water (maybe a handful of ounces) from under the refrigerator. Is there a drain from the refrigerator that could be plugged or could water be condensing from the heater use? It isn't much water but I want to stop this before it does damage something. We're in AZ where it's pretty dry so I'd be surprised if it was condensation. The sink is on top of the refrigerator and no leaks are visible from that. Any ideas? Thanks!

I had a leak in my galley with built in a sink and a fridge. It was on water connection to the sink. Different van, different galley design but leaks are leaks. https://www.classbforum.com/forums/f...mps-11084.html
I would check:
1. Was water under pressure either from shore connection or turned on water pump?
2. How do you know there is no leak from the sink?

GeorgeRa, Thanks for the comment. I had the van hooked to shore water. I had the panel next to the sink faucet off so I could see no water coming from the supply or drain lines. My next step is probably going to be removing the refrigerator and seeing if that shows me anything.

I don’t how easy access is to plumbing and here are some potential options to verify the source of the leak:

1. Drain water and pressurize the system with compressed air, just like for winterizing and listen for a hiss

2. or disconnect shore connection and check again for overnight leak

3. or Use endoscope camera to see inaccessible space https://www.amazon.com/Inspection-Fa...lbWF0aWM&psc=1

4. or install a pressure gauge and monitor pressure decay. https://www.amazon.com/Pressure-Univ...80&sr=8-3&th=1
