Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of you situation.

What is the brand & model number of your water heater?

Customer: replied 6 months ago.
richmond 6G40-36F1
Customer: replied 6 months ago.
I had also checked venting to make sure it was clear.
Expert:  Rick replied 6 months ago.

Could be a problem with the gas valve. How old is the unit?

Customer: replied 6 months ago.
just over a year old
Expert:  Rick replied 6 months ago.

Is it in a laundry room or other area with a lot of dust and/or debris?

Customer: replied 6 months ago.
it is in the basement not a lot of dust but does get wet when we have lots of rain . the water never gets to the water heater .
Customer: replied 6 months ago.
most of the time it is dry down there
Expert:  Rick replied 6 months ago.

Ok, given it's age I'd suggest you make a warranty claim. Call Rheem next week at

(###) ###-#### They'll want model & serial number
Customer: replied 6 months ago.
because of the water in the basement they said they would not warranty it
Customer: replied 6 months ago.
I never saw the water up to it but it could have .
Expert:  Rick replied 6 months ago.

Then you could try replacing the gas valve and while it's apart pull the burner and make sure there's no water in the tubing to the burner or the pilot

Customer: replied 6 months ago.
checked that and cleaned with air . there is a white sensor just above where the thermal couple goes into the valve it has 2 wires what does that do?
Customer: replied 6 months ago.
the wires go into where the temp sensor is inside the tank.
Expert:  Rick replied 6 months ago.

I don't see that sensor in the parts list for this model. It could be an overtemp sensor could also be a FV (flammble vapor) sensor but the model you gave is not FV capable. Can you give me a picture of it? You can post a pic here by clickong on ADD FILES next to the send button

Customer: replied 6 months ago.
Trying to send photos now
Expert:  Rick replied 6 months ago.

That's an over temp sensor but the specs I have for your unit don't show it. I have no info on this gas valve (it not the one in the manual I have). I'm going to open this up to my colleagues so one of them can help. Please don't respond (even to acknowledge this post)until you get a response from us. If you respond first it will only delay your answer.
