Plumbing Questions? Ask a Plumber and Get Answers ASAP.
Hi my name is ***** ***** I have been in the plumbing field for 20 years. I will be glad to help you today. Do you know if the spark electrode is getting a spark? Is there an error code?
If it has a spark electrode it may very well be a matter of cleaning the electrode and replacing the flame sensor. If it has a standing pilot and the pilot will not stay lit then the thermocouple will need to be replaced. If it will not light at all then the same answer would apply. Also clean the burner area of debris.
I am not sure about where to get a repair manual or even if there is one. Is the water heater on a stand? Did you see a spark from the igniter? The rod part is the flame sensor. Is there any error code?
