atwood 6 Gal LP water heater stop working after 3 months

we have a new as22Fb 2017 model. after 3 moths , no more HotWater

the lights goes on and off, on and off for a few cycles

outside, we can hear the gas valve open and smell gas, no spark occurs
we are on a long trip and its a pain to take it into a local dealre

has anyone else had this issue?
is there a simple fix?

this is the 10th issue we have had with the unit in the last 3 months

is As quality going downhill???

Is it electric ignition?

Does it have an electric heating element as well? If so use that if you have shore power for now. Can't believe AS would build a trailer without dual propane/ electric water heater.

If you look there is a wire inside the water heater door that runs from the control panel to the igniter. There is(should be) a wire connected in line that has a thermal fuse in it. The fuse is usually wrapped in a little clear plastic tube. Sometimes when the TPV lifts due to thermal expansion of water in the water heater hot water drips on the fuse melting it. This causes a break in the electric circuit going to the spark igniter. It is usually connected with push on connectors so the fuse can be removed temporarily to get hot water until you get a replacement. Sometimes the wind blowing hard on that side of the trailer can cause it to melt as well.

This is what it will look like, you get two so you end up with a spare.

Airstream doesn't make Attwood water heaters. Attwood does.

A malfunctioning Attwood water heater is not an indication of Airstream qualityŚ which may or may not be going downhill. They're entirely separate issues.

The Attwood water heater in my Airstream was defective when the unit was brand-new, but in a different way. It would heat the water, but not shut off when the water got hot, so it heated the water to boiling. Turned out to be a defective thermostat, which my Airstream dealer replaced under warranty. Luckily before I got scalded!

Any shop that services Atwood water heaters should be able to help you. Atwoods are in only about half of the RVs you'll see on the road. (The other half has Suburban water heaters.)

there is a diode on the right brown wire. it reads ok with my multi-meter.
I removed it , no change

when i use my BBQ starter to give a spark to the gas outlet, a flame starts, but then goes out in 1-2 seconds when the gas valve shuts, i guess that the controller sense no heat.

IMH0, there is some sensing or control board issue
i will call AS support and ask for a whole new unit to be shipped. the closet dealer is 7 hours away

Mine behave similarly with a failed board.

No spark and self extinguished when manually lit sounds like a bad board.

Why would you not go to the nearest RV dealer and have him diagnose the problem and if new Atwood parts are needed, have him install them?? As Protagonist said, Airstream does NOT make the water heater. Asking Airstream to ship you a new water heater, when possibly only a simple part installation is required is not a smart thing to do. Get it fixed and continue on your trip. Worry about getting your money back, if you actually have to pay for parts, after. A good RV store that deals with Atwood Will likely repair under warranty. Don't make a big issue out of a little problem.

You could try to disconnect and reconnect the multi-pin connector going to the circuit board on the water heater in case you have a poor connection there. After my 3rd trip the Airstream dealer had to replace the ECO switch on our new 2017 Airstream when the water heater would shut off prematurely. Later, I bought a spare ECO switch on Amazon to take with me from now on and may buy a spare circuit board as well.

Your hot water problem is with ATTWOOD not Airstream. I would call the closest RV repair shop and explain the problem and they should be able to assist you at no cost to you. Heck you may even be able to get a mobile service to come to you, certainly worth a phone call or two. Also, call ATTWOOD directly and nicely ask for assistance and they may send someone to you. My rear AC died shortly after purchase, Dometic replaced everything quickly at no cost. I did not contact Airstream about the AC.

I need to take mine in to the dealer. I keep blowing the fuses discussed in this thread. When I bypass them, the heater works fine.

I had the same issue. I had to replace the control board as it would no longer generate the current for the spark rod. it was only 6 months old. replaced and its works fine.
