Code 11 on a Rinnai RL series unit
HTML-код
- Опубликовано: 16 апр 2021
- Code 11 is one of the biggest codes that could happen to a Rinnai unit.
The code is no ignition and can include a gas problem, vent problem and a ground problem.
Some times it can be solved by just cleaning the fan or the ignitor or flame rods but most of the time you will have to remove the burner to clean it.
If you have a question or would like a Rinnai Guy sticker please e mail me you info to economyplmbg@aol.com
I hope you enjoy this video,

Mike, I cannot thank you enough for your help with my Rinnai unit. Taking the time out of your Sunday to talk to me in exchange for nothing is a great example of the kindness you must exhibit. Thank you again for your videos and wisdom which are so very helpful
Phenomenal video. I feel extremely comfortable with taking on this project after seeing this. THANK YOU
LOL tanks I'm glad I could help.
Thank you for the videos. I simply watched a few mins and it gave me everything I needed to find my issue. 7 screws a wire brush And no cash is all it took. Your the best
This is the best video for working on Rinnai tankless water heaters.
Thank you! Followed your steps and an hour later, hot water again and my wallet isn't lighter. Nice simple steps, very clear instructions and some gentle cleaning and off we go. I appreciate you!
Read through the comments on any of Mike's videos and you'll see the lengths he goes to share his knowledge and help his subscribers troubleshoot issues they're facing. Tonight was my turn.
Mike spent an hour or so in email, on the phone, and through text helping me pinpoint a strange noise issue I was having with a recently installed Rinnai RU199in.
Simply amazing and his time is so very appreciated.
Thanks Mike! For your help this evening, and for all the work you do putting out fantastic videos.
Cheers.
Mike
Thanks for making the video Mike and taking the time to explain in further detail over the phone. I've gotten the code 11 issue resolved. Your video helped make the process go a lot smoother.
Really well made video and without even any edits. Amazing!
This is a fantastic series - very helpful! Your presentation is excellent and very professional. Thank you for creating it!
Mike advised me a third time over phone when I had a question regarding
gas pipe sizing for my Rinnai .. It was very detailed and informative.
Thanks Mike.. You are among the few popular youtubers who walk the talk
of helping out their subscribers.. Much appreciated !! :)
You are a huge help Mike, thank you!!
You’re a genius Sir!! Thank you this took care of the issue
Mike, this saved much time and expense to get my tankless back up and running (and got us our hot showers back!). Thank you for sharing your expertise!
Thanks a lot Sir for this detailed information video!
You are the best !!!
Thanks Mike for this very informative video. Help me sort out a code 11 on my Rinnai unit.
Awesome, this worked like a charm for me! Thank you!
Wow...think you saved my a*#. My heater quit 2 weeks after warranteed. I'm capable, but clueless about these units. Your step by step instruction is awesome and perfect. I can now feel confident 'tearing' into this thing.
Thank you so much..!!
You are a master this video helped me completely very easy troubleshooting after watching the problem I had is gone after follow up instructions you the best 🙌
That's awesome fix. Ty so much.
Thank you Mike ✌
Thank you for the video, very informative… my code 11 turned out to be a failed gasket for the igniter, it literally crumbled when I took it out. Replaced igniter and flame sensor with gasket. Saved me $280. Thanks again
Wow. Thanks so concise. Major props from a plumber gas fitter.
Thank you very much
Goss what a good instructor. Rinnai hire this guy, second thought stuff em. Good job bro.
Great video about six months ago I ended up with a bad circuit board out of warranty. So I ordered new board with chip to upgrade program worked great then this morning got the code 11, burner lights but goes out then tries a second time and code 11’s. Fans working going to test ignitor. Hope it’s just that burner looked to be burning good the few seconds it would light. Keep up the great informative videos
Thanks buddy this worked great 👍
Great video
Mike you are freaking Awesome! I watched your heat exchange replacement video and replaced mine. I got a code 11 and one burner was not coming on. I ordered a new gas block thinking the solenoid was water damaged. Still throwing a code 11 after the switch out. So i find this video, and then at 07:20 the ground wire. Wait I don't remember a ground wire on the gas manifold. So i go back in the box digging around. I have a RL94i, it is a short wire that connects to the chassis from the control box. I never saw it when i put the thing back together. Soon as i connected it and tested, dam thing fired up like a champ. DO NOT FORGET YOUR GROUND PEOPLE! Save yourself the $85 for a new burner. Thanks again Mike!
Great stuff mike. Thanks for the video. This code is something I’ve seen quite a few times from customers. Keep up the great work
thanks Brandon
i guess I am pretty randomly asking but do anybody know of a good website to watch newly released tv shows online ?
@Mohamed Cristian Try flixzone. You can find it on google :)
Mike, good video! I’ve experienced error code 10 several times now and made my own videos on how to fix it. This is the first time I’ve had error code 11 and I followed your video and this was indeed my problem. I’ve never cleaned out the burner or the igniter section since I put my unit in back in 2016. It was a dirty job and I probably should’ve had a mask on when I blew it out. The burner was clogged with white, burnt residue, and the orifices were clogged. Took it apart and cleaned it all out with my wire brushes, air hose, and vacuum cleaner, and it works like a champ now. I was careful not to break the gaskets and did not replace them. Hopefully that was not a bad thing and I did not smell gas after I turned it back on. Thanks for getting my RL94i back up and running.
Huge Help. Thank you so much.
Great video. 👍
Thanks so much for this!
Thanks so much, we are stuck at home with a toddler in isolation and plumber did not turn. We had a wasp nest restricting flow and this showed me how to open it up. Greatly appreciated
Rinnai New Zealand also seems to have average support
Thank you-- excellent!
Have a R75LS unit. It stopped heating during a shower a couple times but cam back on after 5 min of being off. No reoccurrence until lately when I had some temp fluctuation but the water pressure was pulsating at the same time. Its outputting codes 10, 11 and 12. Was looking for a suggestion of most likely potential, prior to tearing into it.
Great job
Thaks, fixed my water heater!
I have a Rannai RH180 its been working great for a month and a half: I have a code 11... I took out the flame rod and the ignitor, they were both pretty clean. I tidied them up. The unit started up for one cycle and went back to code 11. Before I take it apart more... I decided to watch more of your videos; the installer has the regulator to close and its all connected with half inch copper. thank you for your videos.
After I replaced new flame rod n ignitor run for 2 mins and show the error code , what should I do next?
Nice video, I’m having that code right now. My unit is only a couple weeks old. So I’m assuming it probably warranty, so I’m not going inside of it. But I’m always curious as to how things work. Being “ignition” I was thinking electrical, but sounds like more of a combustion not sensed code, probably watching for heat at a thermocoupler or something. Seeing that it air flow could be an issue I hope it’s not critters blocking the breathing, my unit is outside.
Again thanks for the detailed video!
Mike love your videos. Since I'm not a plumber, I learned through experience that code 11 means the unit is not getting gas. Most common reason here in California is that someone hit the gas meter and triggered the earthquake valve shutting the gas off from the gas line feeding the unit.
Hey Maurice would that cut gas off to the entire house or just the water heater gas line?
MIKE I HAVE A RL75I THATS NOT STARTING ON SOME FAUCETS IN HOUSE I HAVE NOTICED THE ONES GIVING THE MOST ISSUES ARE ONE HANDLE FAUCETS WHEN OUTSIDE AT THE HEATER IT STARTS WITH SLIGHTEST MOVEMENT OF RELEIF VALVE WHAT COULD BE CAUSING MY ISSUE NO CODES ARE SHOWING. THANKS FOR THE VIDEOS THEY ARE GREAT!!!
Thank u dude ... great video
Glad it helped
Mike, I can't thank you enough for your generosity. Time is finite, so the fact that you would spend your Saturday evening on the phone with me is beyond generous and kind of you... add to that your willingness to follow up with me later in the week and I'm simply amazed. Information is power and in just one call you've empowered me with enough information to understand the many problems with my install. Thank you & I look forward to being in touch again this week. I hope you have a wonderful weekend!
I was about to do the same but eventually found out it wasn't the Rinnai but a faulty one-way water valve feeding the heater - but Mike did give me inspiration to have a look myself before calling out a plumber!
I'm so happy I just found you.
I have a REP160IN. I made sure all the lines are correct (3/4"), I'm pretty sure I cycled it enough to get any access air out of the line, but it still ignites and gives a burst of flame then shuts off.
What else can I try?
Thanks for sharing the knowledge.
I’ve been following your videos trying to troubleshoot my Dad’s R75 LS.
It’s kicks on for a minute or two and then keeps shutting off. Any suggestions based on your experience?
Thank you, Thank you so much for the very detail video!
As for Code 11. If you've had the gas line open, let's say to work on the gas pipe and the thing isn't lighting off, one thing I haven't seen mentioned anywhere is the simplest thing of all. Plug and unplug the 120v cord to reboot the thing. That happened to me today, and all the great complex instructions will be great for another time, but I had to discover the simple thing first so I'm passing it on.
Hi Mike, I have been watching your videos for almost a year and decided to get the RUR 199ep unit. The unit will fire when the screw is removed from the port where the water column gauge is connected, but will not fire with the screw in. Is it ok to allow the unit to operate with the screw out? If not, what could be the problem and what should we do? We have checked everything: valves open, gas in the tank, proper wc pressure, and so on. Appreciate all of informative videos you have put together. Thanks in advance. Rod
Fantastic detailed video!
Glad it helped!
Mike, thanks for all your outstanding videos. I have the RUR98i with error codes 14 and 11 that runs on propane. I've checked the basics (fuel in tank, no obstructions on outside air intake and exhaust and looked for obvious issues). I flushed the unit thoroughly with vinegar. This seemed to help the unit function for about 3 weeks, but then it started acting up again. What happens during use is that water gets very hot initially for about 5-8 minutes. The water temp then falls off, but if you turn the hot water on-and-off numerous times while taking a shower it will come back on hot and stay hot indefinitely??? Do you have any recommendations for me? I'm not a pro, just a homeowner looking to make a fix. Thanks again!
Out of curiosity, can an error 11. Also be a bad gas valve?
Wow look at those comments. You talk to your viewers? Mike, I’ll subscribe keep it up!
Thank you for the comment, just unplug the unit with no power it won’t try to turn on. Mike
@@ThatTanklessGuy If you’re unlucky like me the unit will not be on its own breaker. I had to cut power to the attic, laundry room, garage, and master bathroom.
good video. i am going to clean my Rennai RL75i burner. at 9:00 minute mark, you had removed the burner and explained about the four solenoid connectors. there was a loose red wire connected right beside the Rd label for the red solenoid connect. you did not mention anything about that red wire. was it always loose?
What are the chances of the ignitor failing itself? I am getting error 11 sometimes and sometimes it works, i already replaced the flame rods.
Thanks for the videos! Where is the best places to buy parts
Great videos!!! I am getting a code 11 only after bad rain storm. My unit is on the exterior of my home. It has happened twice now. The first time it basically cleared itself after I opened the panel, I opened the valve on the bottom to troubleshoot the problem and the burner fired up, steam came out of the exhaust and it was fine until a bad storm came through again last night. This morning I woke up to a code 11 again. Went out, opened the panel, opened the valve, and nothing. I could smell the gas, the blower was blowing air but no ignition. I cycled it maybe 20 times...no joy. Took my cold shower went to work, came home and all is good after it had time to dry out. The unit is 11 years old. It seems rain is getting in (maybe blown into the exhaust) but this hasn't happened before. What do I need to do, replace, etc. to prevent this from happening?
I have a Rinnai R75S, here in Canada. It was working with a lot of fluctuation in temperature for several days, then quit on me. I discovered it has no condensate drainage and when I removed the little temporary loose fitting black plastic cap thick black goop starting coming out. If it poured out that would be great but its too tick to drain, I have no idea how to flush it without disassembling it, which seems unlikely to be possible anyway, so I'll call a licensed service tech. I can't imagine when no condensate drainage would ever be OK. Amazing it has worked for years without this issue manifesting before. 2 45 degree elbows right of the heater, then 2 feet of piping to get out and through the wall.
Yes the top of the unit is clogged with that goo. I never seen that type of clogging but anything is possible. You will definitely need a Rinnai Tech. To take a look at it. Mike
Hi Mike, regarding this code 11 I did all the steps in this video, even I installed a new ignition but still getting the code 11, any advice to try to resolve this.
Thank you and have a wonderful afternoon.
Great video! How much would a plumber charge to do this work?
Hi Mike! I have a 2006 Rennai R85 LP heater that suddenly stopped igniting. (Error 11) I have gas flow to the machine, my ignighters are new and sparking very well and my fan and exhaust is working great. I confirmed that there is gas flow but the could it be the GCV? Everything else checks out?
I’m getting a code 11 on my tankless do I need to shut off gas to turn off machine I’m worried
Mike, Thank you for all your great informative videos. Just yesterday we got a code 11 on our R94 when the heater would try and light but would shut off after exhausting unburnt gas. The flame rods and igniter were covered with scale so I cleaned them off as you had shown on a previous video. Once back together the Heater wouldn't start. I rechecked my steps and everything was back together. After checking and rechecking i found the 3 wire hall sensor from the inlet valve had fallen off due to the deteriorating rubber or glue. I cleaned and epoxied the sensor back on and all is now well. Is this a replaceable sensor without the valve? Would this have caused the intermittent ignition ( code 11) ? Mark
I'd love to know the answer to your last question ❓
We have a new Rheem propane water heater that's showing code 11 and we have a 3/8" propane supply line. Is it possible that poor gas flow cause code 11?
Mines not firing up, it just puts a 1 on the code screen when I turn it on? I don’t see a code 1, I’m thinking the other 1 might be not working?
I just performed my annual flush of my Rannai tankless as I have done in the past. Now when I turn it on, I get a code 11. Research indicates that it is a gas issue. However, the unit has been perfect for 6 years, and I always use the same flush procedures. Is it possible that some are got into the gas line and the unit need to be bled?
Hi,
I have a ridiculous intermittent failure occurring on my fathers RL94i tankless.
The system will run and cycle, then intermittent trip code 11/12 which seems to happen on the same flame sensor. Red wire centered between ignitor and yellow F.S.
I've removed my burner, fan, gas port assemblies. Ensured all is clean. Flame sensor is cleaned and I physically see the sensor in the flame. On my meter I have 24v to ground on the sensor, rectifying at above 1 MA. Therefore this meets spec. I do not understand how the board is tripping this into a code 11/12 when flame rectification is measurable. Therefore I replaced the board. I still have the same intermittent failure. Gas pressures are to spec, dip switches set to correct settings.
What else can I be missing?
I've even swapped a few solenoids to see if the individual solenoid was faulty. Still, reoccurs
Could this cause a gas leak if not done correctly? I have the smell of gas in my garage (where my water heater is) after doing this
Hey Mike ... how do u fix a code 12 ???
Fighting this code now. Did all you showed except didn't remove burner so will try that. Is it common for the ignitor itself to go bad?
It common for the igniter and flame rods to get dirty. Yes it could be bad the burner would be ladt
Stuck with just taking the sensor out… the black housing plastic thingy just slid off and I can’t get it back on or take the little metal part that it was housing off…
i take that back. that loose red wire is a tie wire to hold the group of wires. you called it a zip tie. i get it. thanks
Should I turn off my gas if I don’t have the proper tools
Been out of hot water for three days now with my unit. Plumbers have come out three times and are coming back today for a fourth time. My unit comes on water heats and less than 30 seconds chokes out and stops. Plumber had it working heating water yesterday only when water was running at half pressure from faucet. Once full pressure comes on unit chokes out. Love this unit but these freezing showers suck and it has been cold in 40's here in North Florida. Hopefully they will figure it out today. Also had my gas company put on new regulator yesterday. Code 12 showing. Had unit installed in 2019. Plumber cleaned burner, coils above burner. Took shower last night with shower head button pushed in to slow water pressure to half the pressure and within a few minutes water turned cold.
Can you e mail me and tell me what the plumber has done so far. Did they check the burner to see if it was dirty
@@ThatTanklessGuy Got it fixed last night. I have about 8 to 9 feet of exhaust line from inside my garage up to roof. I just had a new roof and somehow the banging or roofers made one of the connections of my exhaust line come loose enough where the oxygen and exhaust were mixing. It's a 6 inch PVC with metal insert for exhaust. Metal insert is exhaust going out and the room outside of the metal insert with the PVC is oxygen coming in. Two lizards also found inside the oxygen blower. Going to have them change top part on roof with one that keeps critters out. After four nights got to take hot shower last night with big smile.
They did clean burner the second time out.
@@charliewelch328 ALWAYS consider anything else that's been done around the house when something odd happens and an appliance fails for no reason. Often you'll look back and wonder why you didn't think about it. But, you probably didn't know that these units get their fresh air and vent the exhaust thru the same (double wall) pipe to keep them apart as well as proper spacing...
I have a V75i which got a code 11.
All the small orifices in the burner cover had water in them. I blew/dried it out and its working again.
How is water getting into the gas orifices of the cover plate?
If it didn’t get in through the vent you might have a leak in the heat exchanger
I have the RL94i, installed about 9 years ago, now w/ code 11. It turns out condensate seems to dripping into the unit causing corrosion (I have condensate drain, but apparently condensate is bypassing this?). It is dripping directly above from within the unit, so it is not visible without removing the cover. I cleaned the ignitor/ rods assembly, which seems to have temporarily solved the problem, but I need to figure out why I'm getting liquid dripping down all over all the internals. I have the unit in my basement crawl space with a raised snorkel termination in NE climate (to get above snow)
Check the small 1/3” tube coming out of the vent and if you can check the flue collar for blockage. Mike
Ive installed new unit. Works fine then randomly twice it has given code 11. Unit has been installed aprx. 1 month. 3/4 main gas line ran to the unit. About 60’ run from meter to unit. Along that gas line are t’s that feed the cooktop, hvac, and fireplace. Do you see issue with gas supply. Have you seen new units giving faulty ignitor codes
Code 11 is a big code it’s mostly ignition failure but could include gas. That’s gas run us rite on the edge of being to long. I would have run a direct line to the tankless. You need to also look at the grounding of the unit if it’s inside does it have a good ground at the plug and if it’s outside us it grounded correctly.
Mike
Hey Mike your video is great. My Rannai just stopped working with a code 11 and 12. I took it a parts to clean but my gasket are gone. I’ll send you an email maybe you can help me out.. thanks a lot.
Mine still not working
Hi Mike. Great video. Quick question. When I look through the inspection window where you can see the flame when the unit is operating. I notice sometimes the whole burner doesn't light all the way. It seems that sometimes it will light completely and sometimes the left side doesn't light. It still operates but I'm confused why it's not lighting the whole thing. I was getting a code 11 and cleaned the ignitors and flame sensors. It seemed to help with throwing the code but it seems like the unit has no idea it's not lighting completely
The unit step fires the whole burner will only completely fire on high fire
dose a pc824p need extra propane regulator is one on 250 gallon propane tank enough?
It depends what regulator is on the tank there’s a 20 pound snd a 2 pound. You would need the appropriate second stage regulator near the unit. Some times depending on how close the tankless is the tank regulator could be an inches one.
Hello Mike, I have a Rinnai R85 that was originally installed in 2007 which has been working great. Long story short I ran out of propane at my house and was receiving an error code 12 on my wall controller. After having the propane tank refilled, I was still not able to get the water heater working. After refill I now was getting an error code 11. I've replaced both (Electrode, Flame Rod, & Gasket Kit) and (Ignitor). My Rinnai 85 is still not working. Any help would be greatly appreciated?
Email him...
I have a new unit that has never heated the first time and I’m getting a code 11. What do you suggest? It’s an indoor propane unit.
Was this unit brand new out of the box, did you or a professional install it. Did you have a gas tank heater, and is it natural or propane gas. What’s the full model number.
@@ThatTanklessGuy yes
@@ThatTanklessGuy yes it was new out of the box. I installed it. The only model number I can find is v65i. It’s a propane unit
Sigh….. I’m not winning. I really have learned a lot from you. I’m not a pro installer but a long time handyman and aircraft mechanic. I purchased a V94i a few months ago and completed the install but ran out of time to troubleshoot. REU-VC2837FFU-US. Natural gas. In the garage. Replacing a previous unit that worked great for 15 years. Mono meter shows 8.5WC dropping to 7.4 when trying to start. H2O pressure is 50ish. --turning it on then a hot water faucet will attempt to heat. I hear what sounds like gas flow and then an igniter will cause a rather noticeable gas “pop” (like a delayed ignition) but doesn’t stay lit then shows a code 11. I have reviewed the install manual again and all appears correct. What am I missing? Seems like a gas issue? Thoughts?
Hi Mike, I have a Rannai V75 it’s 6 yrs old. Getting the error code 11, cleaned the electrode assembly, checked the ignitor for spark didn’t get any so I ordered and replaced the ignitor but still no hot water. Could the main board be bad?
Yes that part of the board could be bad
@@ThatTanklessGuy While I was waiting for response I was researching if I had to reset error code. Found that to reset controller I had to empty water then press on/off five times. Well I went to empty tank and as soon as I release water pressure valve the water heater turned on??? Now it’s running fine! Can I get an expert explanation as to what happened?
Hello, my Friend, I have a Client, who has a new house with 6.5 bathrooms and he is looking for a natural gas outdoor water heater which one do you recommend?
Juan, a 6 bathroom house would require two unites. One RUR199EN and one RU199EN The RUR will give recirculating capability and the RU unit will be there to take over any additional load.
Mike
Thanks, you are the Best
Any video about Rinnai RUS-v511b model?
No I don’t
I got a code 11 today and my gas has been running still
Just unplug it until you can have someone check it
I have a code 33 what should I do
That’s the heat exchanger outlet sensor it would need to be removed or replaced. There is a very tiny O ring sealing it be careful not to damage or loose it
I was flushing rennai while it was flushing I got code 11 flushing .
