Not sure if anyone is still following this thread,but just in case, I have a water heater issue also. In my case the heater fires up and runs awhile then shuts off. Then when I open the hot water faucet, I get maybe a half cup of hot water, then a cup or two of tepid water, then cold again. It's an Atwood model G6A-8E with a 04/22/14 date label. Any suggestions would be greatly appreciated. Thanks, Larry
