Error code 11 on my rinnai

Hello -- I am staying at a house with a rinnai energy saver heater 1004f and am unfamiliar with gas heaters. An error code 11 keeps flashing and I have gathered from this site that that means its dirty. I dont have access to a manual or anything like that so I was wondering/hoping if someone could give me some more information on the process. Thanks -- b.e.g.

A code 11 also means that it might not be getting any gas. On thr right side of the unit you will find a small door. open it up and make sure the valve is in the open position. If it is, you should contact your gas company to come and diagnose what is going on. The Rinnai is not a do it yourself fix it type of heater.

    Just fixed a Code 11 myself and with no help from Rinnai or plumbers.
    Pulled the 2 piezo (porcelean) ignitors from the top center of the unit and cleaned them with a bit of sandpaper. Be sure to re-orient the ignitors correctly!
    The unit is now working perfectly.
    I could not find this information anywhere, just kind of figured it out - good luck.

    Thanks for the tip @phcancilla, my unit had three ignitors that were pretty well crusted over. I used a rough emery board to polish them.

My Rinnai 1004F giving me error code 99

This fusible link may be open. Try jumpering the two leads and see if the unit operates. If it does replace the fusible link. Do not operate the unit without the fusible link for an extended period. It is a safety device and is there for a reason. Hope this helps.

Do you get an error code? 11. 12 68, 72, etc. Does the combustion motor come on. You should be able to hear it. Is the exhaust and air pipe clear? Is the air hose hooked to the back of the stove?

Rinnai 1004 F Error Code 11

Code 11 is that the unit is trying to light but does not sense a flame after 5 seconds. Usually means you have run out of gas if you are bottled gas. Check your bottles are turned on if you are on LPG, you might need to change over manually. Have you anything else on gas?

I have a rinnai energy saver 1004f heater and as soon as I turn it on, it starts blinking either the number 11 or 12 and the heat shuts off. Help!

Ignition failure caused by either lack of gas, the electrodes are not the correct gap, restriction in the venting system or the spark is grounding prior to the electrodes. Check spark by holding spark wire close to cabinet (1/4"). Check gap across bull horns (electrodes) they should be no more than 3/16. Make sure all gas valves are on and all wires to gas valve are tight. After these checks, you will need a qualified technician to perform some tests on components.

I have the rinnai energy saver 1004f.. Do I have to put water in it for it to work?

Absolutely not. It does help with the humidity but you will find it empty each day because air blows over the water tray when on.

Blinking 12 and I have no manual to indicate what that means.

A 12 code indicates a "Flame Failure" check that the gas valve on the right side of the unit is turned on. If you are using propane have you confirmed that the tank has fuel? You may be able to download the owners manual from the Rinnai website.If not you can contact themat 1-800 621-9419.
This is a great heater and the Rinnai people will be helpful. good luck!
