I can get the pilot lit, set the heat level, and the burner will ignite heat up and reach the heating level set. When the burner shuts down the pilot will diminish and go out, if I try to relight the pilot it will diminish and go out, after holding it down to allow the sensor to heat up, when I turn the dial to a setting. I have to wait until the heater cools off to light the pilot and have it remain on again, then once the burner cycles it does the diminish and go out thing again.
-   I also have the same problem. I sat and watched the cylcle to see when the pilot was actually going out. After becoming impatient, I decided to turn down the thermostat to make the cycle stop sooner. While still in the warm range the pilot would stay lit. after the water got a bit hotter (top of the warm range) the burner turned off and the pilot seemed to slowly extinguish. I was expecting to see it being blown out by the burner shutting off but that didn't appear to be the case. I cannot re-light the pilot until the water has cooled. I have replaced the Thermo-coupler.

-   Seems no one on the net can answer the question. It's gotta be a clear cut answer to such definate symptoms. Your description of problem is my EXACT problem also.-   floydgator1
Check regulator on the unit.
Check pilot unit on the heater
use soapy water to check for leaks if see bubbles turn off main gas supply valve.
always turn off gas supply before any checks or repairs are made
when all else failes call your local gas provider to check heater and gas supply

Our water heater will heat up the water then after a few moments it will go cold for a few seconds then hot then cold. It makes for a very uncomfortable shower.
