Rinnai tankless water heater code #11

[@cromy6]

Just used this video today on a 15 year old unit that my dad never maintained. This got me my hot water back for free. Thank you so much!

[@MiHeatingGuy]

Fantastic!

[@cromy6]

@@MiHeatingGuy The gasket around the flame rod/igniter probes just fell apart on me. What is that fluffy gasket for? Whats it made from? i need a new one and no one in my town sells Rennai parts.

[@MiHeatingGuy]

You should be able to run the unit without that gasket but I would try to order one online. Just prevents air leakage in front of the igniter

[@cromy6]

Your a superhero! Thanks again :D @@MiHeatingGuy

Mine is a year old. I cleaned it twice for error code 11. No blocks that you can see. I did the same thing, removed the burner and blew it out. Fixed it, but it gets annoying. Thank you for your video. I thought mine was defective until I saw your video. Now I feel better. Thank you.

[@PhilipZurcher]

Thanks for the video. The video helped convince me that I could check it out myself. I have the Rinnai RL75 and the general layout is very similar to above. The solid metal plate (marked VBFF above) with black screws covering the gas manifold does not need to be removed from the gas manifold main cover behind it. Only remove the gas manifold. to get access to the heat exchanger.

[@peterkramer5048]

Awesome!!!...thank you so much for this video......It has certainly given me confidence to go ahead and attempt the maintenance. Greatly appreciated!!

[@simonleung9396]

Awesome video! It worked for me! No special sealant. Spiders was the issue. Took me about an hour to complete (I'm non-mechanical). Vacuumed out the lines after using some tools to dislodge the cocoons.

[@MiHeatingGuy]

+Simon Leung that's great I'm glad this video helped you thanks for watching

[@lesgray3355]

Also be sure to check the propane tank gauge before tearing into a tankless unit! Learned from personal experience lol! Seems that when someone quits paying their gas bill it cause code 11 too.

[@guyserapion6453]

Thank you for posting this. My model was slightly different but the same concept. I pulled out the heater core and blew it out with my air compressor. I reinstalled it and it fired right up. There was debris and dead bugs in it. This saved me a call to the repair man. Thanks again for the great information.

[@dexspeed1122]

how do you test for the igniter will it click if the unit turns on?

[@gr8ride411]

I've lived in a newly built home for three years in an area where the water is considered hard. We don't have any water softener or conditioner yet. Recently we started getting a Code 11 so we called one of two manufacturers service companies. He saw the Code 11 and immediately asked if we'd flushed the unit yet. We hadn't, so he concluded that the Code 11 was due to mineral build-up and wanted us to installs Nuvo H2O water conditioning system to address the issue. I told him we'd wait on the Nuvo for now until I checked on a few things first. I decided to flush the system myself with plain old vinegar. So far everything is working without any problems. The Rinnai RL75 is installed in our garage. Do you think it can also be the burners being clogged? Or can mineral deposits also trigger the code on the display? Thank you for a good video on this piece of equipment. 👍🏽

[@stevieg4201]

Yes, the burners and the inducer motor both have to be cleaned, most of the time on a yearly schedule, Please have a trained tech do this for you though, Its a gas fired unit and things can go wrong.

[@aprillim]

Steve G May I ask how did you solved code 11 issue? I got the same and pro said needing cleaning service also. But I don’t believe him because code 11 is ignition issue. I scratched the ignition rod according to another video and it worked for two weeks. I scratched it again, another two weeks, now I got 11 again. I started to doubt my way. Any help from your experience will be highly helpful because my pro wants to charge $900 for flushing and trouble shooting.

[@aprillim]

gr8ride411 I think my question on the above for Steve is actual for you, thanks a lot to read it, please.

[@fsmeltz7058]

I'm not on a well. But I added a flush that I can use to blow it out. I wish I could post a pic of it

[@rikstuff4823]

Same issue here...

[@fsmeltz7058]

Great video brother! Even though I have a license. Home heating isn't my thing. Big thank you for the tips and advice

[@MiHeatingGuy]

Thanks for watching!

[@FluxinShitUp]

you don't have to take all those screws out .... just the parameter screws around the burner plate and gas manifold

[@joseb1700]

Hey just did what u said n man it worked!!!!! U are the first person that gave advice that worked for me!!!!!!! I fucking love u man . Probably saves me 3-400 bucks ..I still can’t believe it works so I took a shower n it’s WORKS!! Thnx thnx thnx thnx mine was full of grass clippings n soot . Thnk u very much!!

[@kongyang6859]

Was your also leaking water?

[@testtesttesttesttest884]

Awesome! Was this an RL94?

[@raghutadimeti8271]

I want to buy Igniter for my RL94, where is the best place to buy?

[@frednepa9690]

Another good video, thanks!

[@neilkan3074]

I have this RUC98I unit, could you do a video or videos of cleaning the burner and heat exchangers.

[@Rickmosin]

I am having this problem right now but he didn’t explain how to get that whole unit off I seen that you got it off but I’m afraid to break something I was just attempting to do it and I didn’t want to rip any gaskets so I wish she was a little bit more details but it is a great video thanks for put it out because it’s probably going to help me

[@michaelpetrella555]

Great video liked to learn how to pull the burners.

[@jasonhayes3944]

Awesome job 👌

[@TomokoAbe_]

I was about to get a tankless outdoor heater..then I remember this video and all the bugs that get into it. I know one thing about Florida--the bees will find a way in and build a nest right in the device.

[@charliestovall9953]

it will get too hot for bees to make nest in it , I have had two outside heaters for 10 years never had a bug problem.......................JS*

[@TomokoAbe_]

@@charliestovall9953 These florida bees can adapt to anything, and will get into anything. You can bet on that. So do the ants -- but if they get into the electronics you can bet they will cause a short. You cannot say the electronics "get too hot" because the water heater itself will be destroyed. What you have is a computer inside the tankless water heater.

[@zeroturn7091]

Just removed a paper wasp nest and three mud dauber nests behind the access panel today, and I haven't even reached the combustion chamber. I can just imagine what's waiting. I'm also having EC 11.

[@kongyang6859]

Was yours also leaking water? Lmk plz

[@mikepedrick8161]

Do I not need to worry about the gasket on the burner cover plate? Does it need sealant? Thanks.

[@easleydoesit.6772]

Great video thank you.

[@mapquestHs]

Never again!!!!! Get one if you enjoy complicating your life! I’ll spend the whopping $25 extra in energy costs to run a NORMAL tank dead reliable hot water heater. I have wasted my time and money on several different makes and models and they all suck!!! I especially love it when the electricity goes out mid shower and the water immediately goes cold, my wife loved that one! If your going to torture yourself with one of these miserable units at least go for the standing pilot unit. I have both and at least those don’t leave you in the cold. Unfortunately I designed my hot water heater cabinet for these darn things so in order to go back to a reliable tank heater it’s a lot of work. Hopefully this reaches someone who’s on the fence about purchasing a tankless and it pushes them to go with a tank water heater.

[@justinfrias9030]

Holy shit that was a lot, great vid! How long did that take 2 hours?

[@NorCal-refrigeration]

Good video thanks.

[@joseb1700]

Mine is doing the same thing starts beeping n showing 11. Gonna try the same thing . Any advice?

[@timcat1004]

@2:50 you are missing a screw.

[@pablogaviria9265]

Mentally ? As in 2 cans short of a 6 pack ?

[@benjamindunstall3904]

I just pulled out the igniter and blew it out with a air gun.. Fixed in half the time

[@TomokoAbe_]

I wanted to get a tankless but seeing all the videos of issues I went for a conventional gas tank

[@nemoomen3911]

You made the right move...I usually have to fix or replace my tankless water heater every 3 to five years....expensive junk

[@markgosser9578]

billywilliamjr - Even the endless water is a problem when my kids take hour long showers, what a waste of natural gas, water and a larger sewer bill. I think it cost double of a conventional tank.

[@MiHeatingGuy]

That's what I tell my customers It's for convenience not energy savings

[@TomokoAbe_]

@billywilliamjr Endless hot water also mean HIGHER water bills. More waste. Strange everybody including the GOVERNMENT wants people to go tankless.

[@philiphickman1787]

An older friend expects me to fix his Rinnai Rv53e. It's showing code 14. I don't fool with tankless heaters. Anyone know anywhere I can find a video on that code?

[@H4zuZazu]

That's a pretty dumb construction of the Burner.

[@clarksafg]

Man those things kinda suck to service on for me at least..but I do deal with cheap stuff..good job.. one time I was servicing a new install and the hatters was cracked(90% unit) because it was installed improperly..then have to tell the customer that the new unit thay bought cant be repaired because thay(10 old new in the box unit on line)dont make the parts anymore and that the warranty is up so that will have to buy a new one...ya me...lol

[@thinhphan5404]

Thank you. Some how, mine came back to work again.I think in the future, I need to pull the igniter to clean.

[@RobHVAC]

Great vid

[@naldana6996]

Thanks for the video, thanks to you I was able to enjoy a nice hot shower.

[@f.demascio1857]

SOOOO many screws. I think the creator of the Rinnai has a brother in law in the screw biz.

[@stwaldman71]

Did this guy just wake up?

[@ChemiTibet]

Can you come do this to my system..i have code #11 and can't afford the price to fix it.need help

[@ginaBabyonyt]

Is this important this is what came with my appartment and I just got that error code then it went away...

[@israelmartinez8272]

Dude. Show step by step. Don’t tell how to. Show it!!

[@Wetboyslim]

My Rinnai R75LSi fails after six years of operation. Its heat exchanger leak.... :(
