When your Rinnai water heater flashes a code 12, it means that the temperature inside the unit is too high and the unit is shutting down for safety. This can happen for a number of reasons, such as if the thermostat is set too high, there’s something blocking the air intake or exhaust, or the unit is overheating. If you see a code 12, turn off the power to the unit and call a service technician to have it checked out.
If you’re getting an error code 12 on your Rinnai water heater, don’t panic! This just means that the unit is having a problem igniting. The first thing you should do is check the batteries in the remote control.
If they’re low, replace them and see if that clears the error code. If not, you’ll need to call a qualified technician to come take a look at your unit.

Rinnai Heater Error Code 11 Fix
If you’re getting the Rinnai heater error code 11, it means that the temperature sensor is faulty. The easiest way to fix this is to simply replace the sensor. You can find replacement sensors online or at your local hardware store.
Once you’ve replaced the sensor, your Rinnai heater should work properly again.
Rinnai Code 10
If you have a Rinnai water heater, you may have noticed a code 10 error message on the display. This code indicates that the water heater is not providing enough hot water. There are a few things that could be causing this problem.
First, check to make sure that the water heater is set to the correct temperature. The default setting is usually around 140 degrees Fahrenheit, but you may need to increase the temperature if your home is in a colder climate. You can adjust the temperature by pressing and holding the plus (+) button on the control panel for three seconds.
If the temperature is already set correctly, or if adjusting it does not fix the problem, there could be an issue with the gas supply to the water heater. Make sure that there is no blockage in the gas line and that there is enough pressure for proper combustion. You may need to contact your gas company or a qualified technician to check these things.
Finally, if neither of these solutions works, it’s possible that there is something wrong with the water heater itself. In this case, it’s best to call a professional for help troubleshooting and repairing your appliance.
