water heater won't stay lit

Most likely it's a spider web in the gas/air mixture pipe. Take it off and push a strip of a rag through it and see if a web comes out. I had this issue and looked in the pipe and didn't see anything. $50 for a repair guy to come out and stick a cleaner through it and show me the spider web.

Keep a flea and tick collar in the hot water heater compartment. Spiders are attached to the propane.

I've done that and it didn't do anything. The burner lights for a second or 2 and then just shuts off?

Sounds like the thermocoupler, take out and clean and put back in. If that does not work replace.

Is it pilot or dsi?

I assume the thermocouple is the piece with 2 tips on the end and is right by the burner? That's the only piece in the burner area?

It's dsi.

Does it click, click, click and then after 5
5 or 6 seconds the flame quits?

Yea the burner actually lights but then the burner goes out?

Check the shutoff also...did you bump the winterize valve closed by mistake?

If the tank does not have water in it the burner will cycle but not stay lit...
