Pilot light goes out when i release the button

Question posted under Reliance gas water heater.
Add comment for different brand.
Age of heater is unknown.
Status light indicates one of the Honeywell electronic gas control valve.
Status light not blinking indicates that water heater gas control not receiving electrical power for power vent models.
Or thermocouple is bad on non-power vent models

Depending on model, and age, the thermocouple can be tested and replaced. Or entire burner assembly is replaced.

If the gas control valve has gone bad because of power surge or other anomaly, then the power-vent type gas control is removed from tank and replaced, while the non-power-vent model is module and can be snapped off front of unit.

Lowe's hot water heater pilot light will not stay


If it is one of the new ones with the fancy gas control and the blinking light... does the light blink?? or not??
If it is blinking then the pilot should stay lit...
If it will not blink then the sensor is bad or not in the right place...

Or... the gas control is bad... this is happening alot...

If it is brand new... take it back...

Bosch will give free tech support to figure out your problem. 800-798-8161. Check your paperwork if it is still in warranty they will send free replacement parts. If out of warranty go to for replacement parts. Check the "Flow switch" a long two tubes with two little micro switches and a little round hat or sombrerro that MOVES when the H20 is turned on. IF YOU HAVE ONE OF THESE, it should turn on one or two micro switches. If you have this part it should be described in your "Owners manual". If you no longer have the owners manual you can get one free at It will give you trouble shooting guide and or you can call them even out of warranty then purchase replacement parts.

Noritz f 76 error blinking f 76 and on off light blinking at the same time. Everything works fine turned on and off hot h20 it goes to burner on 120 and then goes back to blinking f 76 after burner...

F76 is a communication error between two quick connected heaters. To clear the code, disconnect power from both heaters, wait 20 seconds, then reconnect power.
