Have you tried temporarily removing the thermal cut-out from the circuit to see if ignites then? It's the little resistor looking thing inside the plastic sleeve/cover that runs to thermostat. Disconnect it from the thermostat terminal, and from wire that is on the other end, and you should be left with a female spade connector at end of that wire. Connect that directly to thermostat terminal where the other part was connected, and try it. If it works, the thermal cut out is no good and needs to be replaced for safety reasons, in case of flame out of control, it blows and shuts gas valve off.

My hot water keeps shutting off after I start it. It runs like 15-30 seconds. What's up?

Sometimes that will happen if there is not enough (or any) water in the tank. Also, there might be a little air in the water line(s) if you had the thing apart. Keep trying. Good luck.

Atwood 6gal self ignite wont stay lit

Are you sure of model number, as it doesn't indicate electronic ignition. That said, if you do have electronic ignition, there is a small thermal cut-out in power line (brown wire) to thermostat terminal. It is inside the clear plastic sleeve and is connected between power wire and thermostat. Pull it apart and remove that thermal cut out temporarily and just connect wire direct to thermostat terminal where other end came off. Now try it, if it ignites and runs good, replace that thermal cut out. If no better, get back to me. That thermal cut out is a safety device in case of flame up, so be sure to replace it once diagnosis confirms it is defective.

By model number it tells me that you have Electric element, as well as gas with electronic ignition for the gas, is that correct?
Any 6 gallon Atwood will work, and if you want to have all the same features available, you simply order another 6 gal, with same features. If you decide to forget the electric element, and just go with gas and electronic ignition, they should be able to order you just that tank. You can even order a tank with manual ignition, and forget all the other options if you wanted to. Personally, if it's got hydro and electronic ignition for gas, I'd replace it with same, unless I have no access to hydro, and will never use that option. If all those options are working on yours, you can just replace the tank, rather than buy all those items new on a complete tank. Any 6 gal. Atwood will go in the hole, it just depends on what you decide you want. I don't understand what the confusion is about, but maybe I'm missing something here.

Does yours have the little cut-out diode looking thing in the plastic jacket installed between power wire and thermostat? If yes, remove it from the circuit and connect female spade of wire, to male spade of thermostat,(just removing it to by-pass it) and try it now. Let me know what happens.

I have a GC6AA-9E and the Pop off valve lifted and sprayed all the electrical components and now the igniter will not spark. Any ideas where is the best place to start troubleshooting the controls.

Look for the little round temp switch inside little plastic sleeve, below pressure relief valve . Look where is plugs into at both ends carefully. Now disconnect it (take it out of the circuit) and hook the one end, to terminal where other end went to. Now try it.

Atwood GC6AA-9E water heater isnt working properly

The ignitor is also a flame sensor. If it's not working to ignite, good chance it's not sensing flame to keep gas flowing as well. Could also be board.

I have model gc6aa-9e water heater. I think i blew the 120 element by turning on breaker B4 filling water tank after winter; The schmatic that came with camper shows part # 91160. Is this corect and if so...

Yes, That will do it. Most RV appliance parts can be purchase at RV dealerships that have parts department. Camping world has always been very helpful. As far as A part # is concerned I can't confirm although it is good to have it and the make and model of the unit. Good Luck
