Code 11 Rinnai water heater. (The actual fix) 

Thank you so much!! Today is Saturday, and the people we could call are closed. I didn't want to wait until Monday, so I followed your instructions. I cleaned the ignition with a dollar bill just like you did and now I have hot water for church tomorrow! You're amazing!

Thank you so much!! My water heater was working in minutes and saved me big $$ on a repair man.

This video that wasted none of my time helped me get hot water restored fast. Saved me hassle, time, and money. Made me proud of myself too. Thank you for helping people like me! I wish more videos were as authoritative and succinct as yours.

I can’t say how much I appreciate this video. I was sick about having to spend $3500 for a new Rinnai (plumbers were scheduled to come by tomorrow AM to do the swap) and then I watched this. Figured what could I lose? Well I took it apart, cleaned it like you suggested, put it back together and VOILA! Hot water and no error code! THANK YOU!!!

Thank you so much. You’re saving so many people from being taken advantage of over changing repair people.

Thanks so much for the excellent video and explanation. I am barely qualified to use a screwdriver, but with your guidance and a dollar bill we have hot water again.

THANK YOU!!! Was able to get my elderly Mom’s unit back running because of this video. Thanks for a great video and saving her a couple hundred for a service call. You are the man!

Just got this code today twice. So not at a hard down yet. Hopefully it will work past Thanksgiving and I will tear it apart on the weekend. Freaking COVID hit me on my first vacation for the year and can’t get any of the planned crap done. Now this. Thankfully we got guys like you posting the videos to help us out. Thanks!!

I resolved the code 11 error on my Rinnai unit after watching your video. Thank you for this excellent video!

Cleaned the ignitor electrode and both flame rods... that was the problem, thanks man!

Great video and worked perfectly. After disassembling I found a moth, wasp, and a lot of debris I blew out with compressed air. Definitely use a strong magnetic screwdriver as suggested to remove the 2 lower screws holding the burner in. One fell off the screwdriver and went into the fan housing. I removed the 3 screws holding the fan in and removed it easily, along with 2 more bugs and debris.

You helped my family tonight

I told a plumber I cleaned the flame rods with a dollar bill, he said that was good, but recommend I replace them for a longer lasting fix. They were about $32 on Amazon.

Got it done, thanks to this video. Thank you!

This video just saved the day. Thanks Brother

I love you! I just fixed my heater! Thanks a lot 🎉😊😅

This worked perfectly. Thank you!!

Wouldn't surprise me if this is my issue. Gotta move stuff in the garage so I can get to my breakers. Feels like a powered off project. Pulled my error codes, had 2 code 11 followed by a 52.

Bro, you saved me so much. Thanks a ton!

Thank you this helped

Thanks for your assistance.

I have a brand new i120cn and get no flame with code e110 or other models would throw 11. Now, I converted the unit to propane with a 65 foot 1/2"copper tube. I know now this was too long. So I moved the tank closer and shortened the line to about 30ft. But guess what, still no ignition. I tried everything, of course not taking apart anything because it's brand new. Whelp

Phenomenal video Sir. Have a question. Do I have to turn off the Gas coming in to the heater first ?

@dswhite42 0 seconds ago Thanks very much - this video gave me the confidence to get into my Rinnai v65 and solve the problem myself. I also appreciated your tip about using a dollar bill to clean the flame rods and the igniter. I'm not sure if you're still responding to comments a couple of months after the video, but for my setup, even though the heat is working again, there's now a fairly significant odor of natural gas whenever the tank is running (not just during initial startup). Could I have missed something putting it back together? Do I need to replace some gasket somewhere?

I think him and the spider are running a hustle together

You should turn off the breaker before touching the unit right?

HELPPPP..... I have a code 11 and tried everything and still not working. The flame dies after a second. It's as if a solenoid isn't opening or is closing for some reason. Maybe bad thermal fuse?

I've got a brand new one. Just installed it and it's not heating the water. Code 11. Any suggestions?

Thanks! Worked for me :-)

Thanks for a great video. I keep getting code 11 *after* showers; if I turn the heater off and back on, it works fine for a few hours or a day, and then after a long shower (when the water is turned off), it will show 11 again. I've replaced the ignitor/flame rods, cleaned the fan, and even replaced the entire burner. Now we just cycle it after every shower. Hoping you have any suggestions! Thanks.

Thank you

Grear video my friend,have been trained and certified by rannai?

If i replace the electrode, flame rods, all three and still does not heatup, but no error code 11 anymore, then what do i do next

I had a question for you I need to replace any of the gaskets

What if I did both of these things and it worked for a bit but now it's intermittent?

this guy sounds like Matt Damon in Goodwill Hunting. Like if you agree!!

No Ive just been working on them a long time

This a great video and I want to give it a try. Thank you. Where can I buy nitrogen compressed air and is there a guidance on the pressure settings? (This is going to be my first DIY, I was able to remove and clean the ignitor, and the next step is to use pressured nitrogen air on the inner parts) I see this on Amazon, is it good enough for the job, and what kind of pressure settings I should be using?

Mexicans cut the steel pipe and thrown out the cap, put a roof jack on with a cap. Unit quit working
