Thanks for contacting ManageMyLife.com. I understand how frustrating it is having trouble with your water heater not working properly. We are here to help. I suspect there is a hot water leak or a bad thermostat. I recommend checking all the plumbing for a dripping pipe or a faucet. If the thermostat is not working properly, the water would be scalding hot. It may also trigger the pressure relief valve, on the side of the water heater. To check the water temperature, just turn on the kitchen hot water faucet. Next, after the hot water has ran for about 30 seconds, just fill a glass of water and check the temperature with a thermometer. The water temperature should be between 120-135 degrees. If the water temperature is close to 180 degrees, the pressure relief valve may have tripped. That would cause the water to drain out the side pipe. Adjusting the temperature setting on the gas valve, should lower the water temperature. Otherwise, the gas valve needs to be replaced. The part number for the gas valve is F145-1555. The gas valve is something only a qualified service technician should replace. I hope this helps.

Hi John, Thank you for your response but that is not it either. I've turned of the pilot and then the gas line and then restarted the whole thing. I put on the low setting. Burner kicked on.. and has been on for more than 5 hrs. Now this happens every day.. I've occasionally it stop burning but then after 10 or so with no one using any water. It comes back on and starts heating it up again. To answer your question, the pressure relief valve never trips at all. Thank you, Ralph

I suspect the flame is low. Otherwise the water should get very hot. That may indicate a bad gas valve.

Hi John, I've replaced the gas valve and the same issue results. So now seem to have 2 separate issues now. If I turn the control to the (A) switch it will remain on for 4-6 hrs then turn off then starts back up again. Then tried with lower settings 3rd circle on switch. It would work and heat up, but after about 1/2 hr or so the pilot light turns off? Is there a way to change the thermocoupler connected to the gas valve? There is a 16 inch piece of plate that holds the pilot view hole but that piece seems to be glued on or something so I'm afraid to pry it open to change the thermocoupler. Please advice

The plate has 2 screws holding it in place. That is shown on the link below. This water heater has a flame arrestor the may be causing the other problem. The maintenance section of the owners manual shows how to replace the thermocouple and clean the flame arrestor. I provided a link to the owners manual below.

Thank you for your question. I know it can be frustrating when the water heater stops working. It's possible the gas line may need to be reduced but a technician will need to check the pressure to determine what will need to be done. This can also be related to the vent or ventilation causing the erratic flame. Water heaters can be very dangerous when not working properly and I strongly recommend having a technician check and make this repair. I'm listing a site you can access, to have a tech come out. Here is a link for the website: Sears Home Services.
