Hello, the unit is not resettable for that problem, the problem might be easily resolved however by cleaning off its flame sensor rod that pokes into the burner flame.

.

I will be back in a few minutes, while I search for the manual on your water heater.

click here for the manual, tell me if this looks like your unit or not, if it does, see pages 24 through 30 for 'thermopile' replacement.

That is not an *electronic gas valve.

If this manual does not show your gas valve. get me the numbers off of the gas valve and the brand name.

Cleaning the thermocouple does not work
Customer reply replied 9 months ago
The control unit has the little litethat is on when you light the pilot light. Before I statrted it was blinking 4 times within 10 seconds. Which indicates it shut down, on high temperature.
Then I lit the pilot lite flame , the flame goes when switched to heating water.!
