Great video sir. I have intermittent code 11. My heater is much smaller than one you show. I will have to remove some aluminum covers to get to flame rods. Gonna try cleaning those first

This was an exact replacement for the old one that lasted about 10 years. kzfaq.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh The top of my mitigation tube by my roofline was just a 90 elbow which allowed too much debris to fall down into the fan, eventually ruining it. Without this issue, I bet it would have kept running another 10 years. When I replaced this fan, I added an extra elbow joint so the top tube now it does a 180, which should solve that problem. The radon guys around here wanted to charge me a $300 diagnostic fee, then parts/labor (probably close to $600 total). I installed this all by myself in about an hour for the cost of the fan; it would probably be even easier/faster with two people. FYI the manufacturer's warranty greatly differs depending on whether you install it yourself (1 yr warranty) or have a licensed installer do it (10 yrs).

Hello, Thanks for making the video. It will be great if each error code solution was time tagged to chapters i.e error code 11, 0.5minute-15minutes, that way you can choose the error code you’re having with ease and not confuse the solutions.

Thank you for taking time to make video. Learnt a lot from it

Super video! This is great! Thanks!

When I did the blue cable ( flame rod 2) only I got a 4. What did it mean?

Randomly tripping code 12...once a month maybe. I'm at altitude...6500 feet. I have the altitude dip switch set right. My venting is 10 feet with one wide sweep 90 degree. As a experiment...I set dip 2 switch 2 on...supposed to be for extra long venting...which I shouldn't need. I want to see what happens.

One of the gaskets completely crumbled and so OHL was damaged. What would cause it to crumble? We're being told nothing can be done, but the gasket should not have crumbled! We've only had this unit for 2 years!!

Was wondering what that baggie of gaskets was for! Thanks!

I see the complexity in the compact high efficiency hot water heating system. Being an electrical engineer, I would say it is not too difficult to design a diagnostic system which points to a one or two defective component to fix the problem. In short these designers have long way to go to design their own control systems in place of subcontracted out to the China mass product design team.

awesome video very helpful When probing small connections use a small paper clip to get into back of connector then touch meter probes to paper clips

How about E 3 code ? I had this code for 5 years old Eccotemp. Hot water was always 120 F. Vent is clean, water pressure, gas pressure - Ok. I did Flushed water heater by cleaning vinegar. Still code E 3 On. Contacted costumer support - no help...

I have bought 3 Rheem tankless heaters so far. First was for my house when we had propane. 2nd was to replace the LP when we drilled a NG gas well. The third was in anticipation of building a house for my daughter. An LP unit. Installation went without any problems, and according to directions and code. (I thought) A couple days ago my daughter called and had no hot water. It would come on, briefly and shut off. On as, light on remote comes on humms a bit and shuts off. Inside 01 flashing. I had her turn on hot water, and heard only a humm, no start. I suspected the fan motor as it's the first to come on. I called the 800 # in the manual and reached a service agent lady who took all our info. She asked where the unit was installed, -in a basement, under a factory built, modular home. Not mobile, modular. She told me they would not cover it under warranty. Ok. How about tell me whats wrong. NOPE. She said it was not designed for mobile home applications. Its in a conventionally built basement under a normally looking home. NOT mobile. It was like talking to a rubber wall. Anything I said she came back with the same answer. I told her Rheem just lost a future customer. I don't give a sh.. where it's installed, she could at least help with troubleshooting. I looked up the HUD document code she quoted, and I could not fine anything that related to a different requirement for mobile home or conventional home installations. Or how they should be built. We tried about 6 different plumbers, 3 didn't work on them 2 don't like to, "there too hard", and 1 said it would be about a week. $275 just to come out. +++ So I'm on ytube checking all different things it might be. Next searching for parts suppliers. FU.. Rheem.

Where are y’all getting codes?

Excellent video

Do you know what causes the cover of the unit to deflect (making a popping sound) when the unit is first turned on? I have asked rheem tech support and no one has a clear answer....any ideas? thanks

That freaking beeping is the bane of my existence. I will never buy a green again. Nothing but issues and no answers from tech support. Not even a year old I have had flame rods go bad, thermistors go bad, ignition coil. Just a nightmare of a unit.

This was very helpful. I unfortunately have once again been getting a code 12 once a day for the last 3 days. Water Heater was installed in in august last year. I spent 3 days on the phone with Rheem support trying to stop code 12. We determined everything was ok installation wise. The manifold set point chart on the heater was not on the unit. In aug, I basically increased the manifold set points until the code 12 stopped triggering every time the unit fired. At what point should I use the unit warranty now that this is starting to occur? I am going to check dynamic and static gas pressures today with my manometer again. It was fine in august.

Got a code 11 on my brand new Rheem tankless gas WH - I had forgotten to turn the gas valve on!

Thanks for the great video. I’m getting a error 12 but it is intermittent maybe once a month but when it does happen it seems to repeat for a day or so. Any idea what this could be?

I have no power to the heart control where you see the temperature an codes

No have power in the termostato, help me

This vid is awsome. Now I need to know what tool is used to test the input gas pressure. Thank you!!!

When is code 13 addressed in the video?

Awesome!!!!!

What do you do if the plastic wrap is torn?

First off all, thank you Rick and thank you Rheem for making this video. I realize you didn’t have to do this, but wow I learned a lot. Second, I have a RTGH-95DVLN, serial RHUNM131307877 tankless. I have error 13, but also failing the flame rod tests (around min 16). My 2 flame rods look very different from each other and have different connectors, but I can only find 1 part on Rheem’s part site. Can I essentially use 2 flame rod 1s (white) instead of a white & blue? Thank you!

Would descaling help with error code 13?

I have a richmond which is made by rheem. I got a code 17 which is not in the manual. Do you know what this code is. I have a gas unit 199900 btu

@10:15 is Code 12

Control panel turned off and can’t turn it on, why?

Great Instructional Video! Why is the thermal safety plastic non-replacable? The rest of the unit is fine. I hate to throw away $1400.00.

O NO not obd2 codes. These things gonna be worst than cars. Check engine lights I thought I wanted 1 of these. Now I may just stick with the old proven and reliable tank. That thing looks like space ship behind the panel.

I'll stick with my conv water heater thank you.

123 volts of ac current 😂

Code 29
