There is water leakage internally. Possible tank or water inlet or water entering from the combo air inlet/exhaust pipe.

My Rinnai tankless water heater keeps tripping the breaker then when turned back on, it begins to beep and displays a code 12. What is causing this? It is new and this is the first time any code came.


Go to Rinnai and get a manual with the error codes... for example a shorted element will trip breaker... wiring problems can cause breaker to trip... anything that causes heat on wire to exceed amp rating of breaker will cause it to trip...

My Rinnai tankless water heater flashes 11 when calling for hot water.


Your Owner's manual should help. No manual, try MFG website, or email their customer service. Or try manualslib.com

How to fix Rinnai code 79


Let it dry out.
If it wont fire because of the error, try powering it off and back on. Also being new, it would be under warranty

How do you fix rinnai tankless water heater code 79


Do not spend 500 on plumber to determine that condensate drain was not installed properly on vent line, and that acidic water from combustion by-product has been dripping down into tankless and burning hole through the special-alloy heat exchanger instead of going down into floor drain and corroding your plumbing pipes.
Do not spend hours fulfilling the required monthly and yearly maintenance, or spend money on service call each year to get the burner cleaned and gas pressure checked on your tankless computer that heats water...
Instead, fix any tankless problem, any brand tankless, same day do-it-yourself for $385, by replacing 1 part: the whole thing:http://waterheatertimer.org/How-to-install-gas-water-heater.html
Do not install tankless.

Rinnai 2532 error code 10


Error Code 10 Problem: Reduced or no air supply to the water heater or there is an obstruction in extracting the flue gases out.

Solution: Make sure that the recommended Rinnai venting is used, there is no obstruction in the venting system, no reduction in diameter and lengths are per instructions. Also make sure that nothing blocks the venting system or fan, and that dip switch and condensation collar are set properly.

Good luck,

Marty

Rinnai tankless water heater


LC is the error code that you get when you have limescale buildup in the heat exchanger. You need to flush your heat exchanger. If you have the manual for your water heater, use it. The manual to mine is attached. The procedure for flushing it is covered on page 12. I suggest that you have a certified Rinnai plumber perform this task as it requires a ciruclating pump and some hoses that you need to connect to your water heater. If you don't perform this task, it is possible that you will need to replace your heat exchanger and this is not something covered by Rinnai's warranty.
