No, it is a low rumble.
I opened the rubber gasket that connects to the fan and nothing came out, no water that is.
It is about 5 years old.
It comes on after the flame starts.
I mentioned the water because the first time I noticed it was the day they did the work. I turned the hot water on to shower. The water got warm, but then shut off completely giving a #12 warning on the key pad.
After that I put the fan on to dry it off, and a few hours later it worked but with noise.
Could the water have gotten the burner dirty? I notice during the period of noise that the flame flickers yellow then comes on a nice blue.
When it first happened and shut it self off the flame stayed yellow, until it went out.
I was happy with the answers but got cut off from further conversations because I hit the wrong button
Well at this point it comes on after a about a second, then works fine.
I think the burner is dirty after thinking about what you wrote. A blue flame then a yellow flame that gets blue right away.
As I wrote before if it has been running for a while and is turned off it does not happen.
I know of a repair shop near by for Rinnai, but they are very undependable.
I also find it odd that this started the day water got into the vent.
I just have to think dirt got flushed back onto the burner somehow.
The burner would have to be open to the air, and if it is water might have gotten in there.
I will give it a try! I own an air compressor, but I was afraid it might blow out too hard. I do railroad electronics for a living so I know my way around a screwdriver.
I have a few detectors around the house, but I will pick one up tomorrow an put it near the water heater. Thanks for everything and I
will let you know how it works.
My zip is 53140 Kenosha WI if you know of a good contractor it would be great. Maybe a different company, while not authorized will know what to do.
Great. Thank you sir!!
I tried to blow it out it and first it went out completely. error 12 I think I blew dirt back where it was not suppose to be. Then I unplugged, to reset it and except when I turn it on and off quickly ( like when doing dishes) it makes the same noise. If turned on and off quickly it is fine.
The little fiber gasket for the spark electrode and flame rod broke up a bit but I managed to get most of it back where it is suppose to go.
I mention that because I took those out of their gasket to avoid them getting dirtier. Can they be cleaned with emery cloth? I noticed a white build up on both of them. Could that be the problem in the first place?
Hello again, a dirty flame sensor will cause the burner to shut down if it does not sense flame properly, but it will not cause the range of other problems you report... The insulator gasket at the base of the flame rod and igntion electrode needs to be in good shape, and clean... if the ignition works the gasket is OK however. When the flame burns yellow it could be going off on the flame sensor however.The big issue here is the burner noise you report and going from yellow to blue flame..thats a key issue with the gas valve, or some other issue with the venting, and that is what needs to be addressed professionally, then while the man is there he would normally look over these issues with the insulator and dirty flame sensor..Stay in touch as needed.Phil
Ok I 'll make the call on Monday. I will call the authorized place in town first, hopefully they will come through.
Thanks for all your help in this!!
As of now, I had a plumber who has worked on Rinnais come and take a look at it. He took the fan out and blew it out. It still makes the noise but after doing various test he still thinks its the fan and has ordered a new one. In the mean time he said it was OK to use as long as I get past the noise stage which only occurs at a certain stage.
He compared it to a tire that is slightly off balance. If you go slow it makes noise then you get to a certain speed and the noise stops. However if you go too fast it comes back again.
I'll let you know when he gets back with the new one which may take a week or so.
Well at least it is working if a bit noisy at start up.
No, as it get going it vibrates.
It starts out fine, and if the water pressure, as from the kitchen faucet stays low it does not vibrate. However turn the shower on and it vibrates, and is loud.
The flame comes on right away with the fan and is a nice blue color. Because of that he did not think it was gas related.
