Tankless Water Heater Thermal Fuse Repair (Error 14) Noritz N-0751M
If you have a Rinnai tankless water heater, you may have received error code 14. This code indicates that the unit is not receiving enough natural gas. There are several possible causes for this problem, so it’s important to troubleshoot and identify the root cause before attempting to fix it.
One possibility is that the gas line feeding your Rinnai unit is too small. The minimum size required for a Rinnai tankless water heater is 3/4″. If your gas line is smaller than this, you’ll need to upgrade it in order to fix the problem.
Another possibility is that there is something blocking the flow of gas to your unit. This could be a blockage in the actual gas line or a valve that isn’t fully open. Check both of these areas and clear any obstructions that you find.
If you’re still having trouble after taking these steps, please contact a qualified technician for assistance.
How to Check Rinnai Error Codes
Rinnai error codes can be a bit confusing, but luckily there is an easy way to check what they mean. The first step is to find the error code on your Rinnai unit. This can usually be found on a sticker near the control panel or on the back of the unit.
Once you have located the error code, use the following guide to decode it:
E01 – This indicates that there is a problem with the gas supply. Make sure that all of your valves are open and that there is no blockage in the gas line.
E02 – This means that there is a problem with igniting the burner. Check to see if your igniter needs to be replaced.
E03 – If you see this code, it means that something is preventing proper combustion.
This could be caused by a dirty air filter or an obstructed flue pipe. Clean or replace whatever is causing the issue and restart your unit.
E04 – An E04 code indicates that one of the sensors isn’t working properly.
Try resetting your unit and see if that clears the code. If not, you may need to replace the sensor itself.
If you see any other codes not listed here, please contact Rinnai customer service for assistance in decoding them.
