2016 Airstream Interstate- no hot water

[Haasman]

Wondering if anyone has some trouble-shooting steps?

-Breakers seem good
-Has plenty of propane AND the stove lights

Have on idea how to figure this out.

Appreciate the help.

Does it make hot water on electric but not propane? The ignition boards in the Atwood water heaters are prone to failure. It is an easy fix with a better board (dinosaur board) that can be found on amazon if that is the issue. Check that you are getting propane to the heater also, maybe an obstruction from insects..

Does the water heater light and stay lit?


Water heater bypassed?


Any hot water from galley faucet, bath or outside shower locations?

Try unplugging and re-plugging the connectors on the control board inside the outside vent. I had to do that once to remove corrosion. Also, I have had mine start, run a few seconds, then go-out on LPG if it had recently rained hard or been washed. Water gets somewhere and will eventually dry out after several start attempts.

We had a similar problem. We had hot water on shorepower put not propane. I found that if the access door was open the hot water heater would work on propane but not if door was closed. I repositioned the insulator on the propane ignition wire and it works great now with the access door closed.

Literally just experienced this problem (and more). Bought a $120. Dinosaur board, but was not the issue - installed it anyway. Here is the link that my husband posted, once he figured out what was happening. Maybe save you a few bucks and troubleshooting headache: https://www.airforums.com/forums/f44...re-209617.html Scroll to his response on 7/23/2020 at 3:53 p.m.

Good luck,

I have found that the connectors under the outside door can get corroded and cause the water to not work properly. When I had this type of issue I just removed the plugs on the control board and cleaned them up a bit. Reinserted the connectors and water heater worked OK again.

Hope this helps,

When you unplug the circuit board clean the terminals with a pencil eraser and coat them with a dielectric grease and reinstall. The mfgs are too cheap to use non-corroding conductors. That fixed my refrigerator.
