Pilot light does not stay on
 
I have 2005 Bradford Defender gas water heater. I am facing the problem with not getting hot water at all.

Following the instructions I could light the pilot but the light does not stay on.

Instructions says - I need to hold the pilot set button for a minute and the pilot light should stay on even after releasing the button.

In my case, as long as I hold the button (almost 2 minutes), the pilot light stays on but the moment I release the button, pilot light goes off..

What would be my next step from here ? Any clue ? Since the pilot light is coming what I conclude is - 1) My ignitor is working and 2)gas is coming to the appliance.. Now what can be wrong here ? what should I be checking next ? Please help

I'd wait for an HVAC guy to reply but rest easy for now, I think it is just the thermocouple. Cheap and easy to replace.

Could be bad thermocouple.
Bad gas valve.
Tripped roll out switch.
Or a tripped ECO, in which case the gas valve still needs changed out.


Looks like thermostat is turned all the way up.

I pulled out the thermocouple and planning to replace it tomorrow with a new one. If this is not the problem, what is tripped roll out switch and/or tripped ECO.

Yes. In the picture, thermostat is all the way up.

Your last pic has the roll out switch.

ECO is part of the gas valve/thermostat assembly on most water heaters, and not resettable.

How do I reset the roll out switch. I want to try this first before buying a new thermocouple.. Can you please let me know ?

Push the button in the middle of it. If it resets, then you know you have a problem that caused it to trip, and need to find out what that is.

Could be a restricted chimney.

I tired to push the block knob but it does not really go in.. what does that mean ?

Its probably not your roll out then.

Could be gas valve, thermocouple, or ECO(emergency cut out).

Do you have a meter to test anything.

No, I don't have any meter to test.. I will go ahead and get a new thermocouple.. I will let you know then..

I put the new thermocouple but it still does not work.. I tried 3 times, pilot gets on but does not stay once I release the button.

With out meters to test things. Can't tell you anymore to do.
