Atwood water heater problem

Is the water heater a DSI model? If so, check to make sure the thermostat and ECO are tight against the tank.

Please supply the model number and year it was made. It helps us help you with better responses.

Not knowing which vintage you have, if the flame chokes out now and then, it could range from insects nesting in the burner tube to an all-gas control valve acting up (a gas supply issue). If you are on electric ignition, there could be other issues with loose wiring, dirty connections, etc (an electrical issue).

Does the furnace work correctly, and do the range top burners burn smoothly for as long as the water heater runs and then acts up? Need to determine if you have a gas supply/control issue with the heater? If the main tank regulator is acting up, the water heater can follow it. We need to eliminate what does work right and what does not.

Hope this helps

Yeah, sorry for not starting with that info. Model is G6A-8E. Looks like manufactured in 04.
I don’t believe it is electrical issue. It fires right up each time. I don’t use the furnace, so can’t speak to its performance. Stove burners burn smoothly.
We did have an issue first trip in the spring, spider decided to make a web in the tube. Cleaned that out and had another trip where the heater worked fine. This just started on this trip and it acted the same for an 8 day trip. It DID heat the water just fine. The flame sounded just like it always does except for the hiccups.

I had a similar issue with the same water heater. Mine started sounding like a jet taking off with the occasional pop or hiccup. Prior to that, you could hear it turn on, but was very quiet during the heating process, then you heard it shut off. I ended up buying and installing a tune up kit and it solved the problem.

PDXRV has most, if not everything you need, including free tech support documents.

Hope this helps.

Thanks for the tips. Looks like I need to take it apart again.

I am thinking you might have and air/fuel ratio issue.. (Air shutter on the burner may need adjustment) but... frankly check out the other stuff too... That's really about the only adjustment on the thing other than ignition spark gap spacting and since it's lighting.. that's good.
